|Type||Size (Inches)||Suitable For|

|Twin XL||38 x 80||Kids and taller adults and those who want to use an adjustable bed frame|
|Full||54 x 75||Good for a single sleeper or someone with children or pets and couples that do not require a lot of leg room.|
|Full XL||54 x 80||More than enough for single sleeper and for couples that need more leg room but can not accommodate queen size due to bedroom limitations.|
|Queen||60 x 80||Frequent choice and a perfect size for most couples that do not need a lot of sleeping space. If you plan to sleep alone this is more than enough.|

Small Single Bed (Cot) Dimensions
These are the mattresses specifically designed for cribs. It can also serve as toddler beds in most cases once your baby outgrows the cot. Typical measurements are30” width and 75” length.
Twin Bed Dimensions
Atypical single, twin or bunk mattresses are 38” width x 75” length. You’d be hard-pressed to find a bed that is any smaller than this one, other than that of a toddler bed or crib.
Typically this isideal for childrenwho have outgrown cribs and toddler beds, and who are now ready to graduate to a larger mattress.
Additionally, for those who sleep in cramped quarters, who have small rooms or who share a room with a sibling or roommate, Twin beds are an ideal choice. Day beds, bunk beds, dorm room beds or those found in the guest room often use this type.
What is important to note about a Twin bed versus a larger toddler bed, is that comfort is taken more into account. It’s common that, once you reach the Twin size, more quality materials are used, and more engineering centered on comfort takes place. This is because, the older we get, the more we consider comfortable sleeping to be a necessity.
There are subcategories of double beds to consider as well. The Twin XL istypically 80” L while still maintaining the 38” W. If you’re an adult looking for a bed that saves space and still is a comfortable choice, an XL Twin may be perfect for you.
Can I use Twin XL mattress on a King Size Bed Frame?
Yes, you can use two double/twin XL beds in a king frame. If you are in a relationship where one partner requires a different firmness than the other, usually end up being big fans of this setup. This is because Two XL beds can fit snugly alongside each other within a King sized bed frame.
This is good to know for partners who are tired of the fluffiness or firmness of their spouse’s mattress.
Full Bed Dimensions
Full-size mattress measures54’ width x 75” in length, and these are also commonly referred to as “standard double.” Sufficient for adults that need more room than what a Twin can offer.
If you are in a relationship, this may not be the best choice for you, as the fit will be exceedingly tight. Likewise, if you have a dog, cat, or you have a child that sleeps next to you, you may want to consider a wider option.
Full (Double) XL
A XL option is54” x 80”giving you anextra 6 inchesof leg space. If you do not require extra width but want some more room for your legs this is a perfect option.
Queen Bed Dimensions
Queen size mattresses are60” width x 80” length. Ideal for almost anyone, in that it’s long enough and wide enough to suit most any sleeper. For those who sleep with their spouse, child or pet, it might be perfect for you.
When thinking about these larger types, it becomes necessary to consider the living space. These take up much more room than the Twin or the Full, and thus, the ability to freely move around the bedroom may become restricted.
If you have a larger bedroom, then this won’t be a factor for you.
These are slightly wider andmeasure at 66”W x 80” L. Olympic queen is perfect for taller individuals, but you don’t want to upgrade all the way to King, but you could use some more width.
King Bed Dimensions
A standardKing size mattress is 76” in width and 80” in length. It’s recommended that you do not opt for this option unless your room is at least 12×12. This is a perfect option for couples who sleep with their kids or pets and want more sleeping room for themselves.
If you want to compare this to other options,King is same as 2x Twin XL.
A nice fact is that box springs are split for this type, and it makes it easier to carry around and maneuver.
California King Bed Dimensions
TheCalifornia King mattress is 72” W x 84” Lmaking it one of the biggest options on the market. It’s perfect for active sleepers, tall people and couples with kids or pets. Cal King is 4” longer but 4” narrower when compared to a standard King.
It is recommended that you have a large room of at least 12’x12’.

Ok, so you have decided that you need a new bed. But, can you actually put it in your room and still be able to open the door and walk around it?
Let’s take a look at the following illustrations showing how certain mattress sizes will fit in your room.
Frequently Asked Questions
Which size is best for me?
Bigger isn’t always better, but in most cases it can’t hurt. More space could mean fewer sleep interruptions, but if you always prefer to cuddle up rather than spread out, that extra space might not be worth it, especially if you’re on a tight budget.
In many cases, couples will opt for a bigger version of a cheap bed, but if you don’t need the extra space, that money could be better spent on features like cooling or motion isolation. For a better understanding of getting your money’s worth, take a look at our mattress budget guide .
When trying to find the right mattress size to fit the needs of you or your family, these are a few things to have in mind.
- First, if you’replanning on upgrading, make sure you know the dimensions of your current bed. You wouldn’t want to shop for a larger option and accidentally choose the same type.
- Second,if you’re moving, don’t forget to measure the room that you’ll be sleeping in. It is awful to have a mattress that is too big for space. You’ll have issues getting around the room, and your space won’t be as aesthetically pleasing.
- Third,who will be sleeping in it? If it’s just you, you are good to go with a Double. But, if you have a spouse, kids or pets you might want to opt for a larger option such as Queen. King is the ultimate comfort size if your room can accommodate it.

How Long Do Mattresses Last? The Results May Shock You!
Mattresses are pretty expensive — one quick glance at our buyer’s guide will confirm this fact. This is why many people do not replace them – not even after many years of use.
They do not want to spend a lot of money on a new one. Besides, now you can delay the process of buying a new one if you do an excellent job at maintaining your existing one.So, how often should you replace your mattress?
It doesn’t matter which type of bed you have. Most of them are ready for replacement within ten years to ensure a good night’s rest (old mattresses can hurt your sleep quality). Besides, it can last beyond ten years on average, if the owners maintain it properly.
Also, many different factors affect a bed’s lifespan. You can extend its life expectancy by following a few easy steps in the text below. We prepared and wrote down some tips to boost its longevity.
How Long Do Mattresses Last?
Mattresses aren’t exactly cheap, most people replace them very infrequently and consider buying a new one either a chore or a burden. It’s easy to delay or prolong this process simply by taking proper care of whichever type you own. As a general rule, most should be replaced within ten years for best results in sleep and health, however, the average life of a mattress can last beyond ten years or more if taken care of properly. While it is true that how long one lasts depends on different factors, you can easily increase its life expectancy by undertaking a small number of simple steps. Here is a look at a few of the factors that can decide how long should a mattress last, and possible ways to increase its lifespan:
Table of Contents
1. The Type
What type do you have? For instance, is it air, innerspring, memory foam or latex? Each one has its own life expectancy; air and innerspring being the shortest, memory foam being mid length, while latex types are known to last the longest.
- Air mattresses will over time either develop leaks or generally become less effective at retaining air pressure. If they have a built-in pump that becomes faulty, this too can lead to premature replacement. Overall, the average air mattress life expectancy is placed at five years.
- Spring mattresses are good for sharing couples who like a springy and bouncy surface, but unfortunately, due to the inner core being thin metal wire, this type does tend to sag and lose its support even if flipped and rotated regularly. Even ones which have been well cared for will most likely need replacing within 7-8 years.
- Memory foam mattresses are less prone to sagging but not invincible. They too require rotating, and foam does eventually lose its support but after a long while. This type should be good for at least ten years if kept ventilated, clean, and rotated.
- Latex mattresses are the creme de la creme and tick all the boxes for quality and longevity. The naturally hypoallergenic and anti-microbial properties add to the durable nature of latex rubber foam to combine a core which can last up to 15 years.
2. Regular Cleaning
Another important factor which determines mattress life expectancy is to do with cleaning.Howdo you clean it? Do you clean itregularly? Do you give it to aprofessionalcleaner? It’s essential that you clean your mattress regularly to prolong the life. If you do not, it won’t last long at all. This is due to the invisible bacteria, mildew, and mattress mold that can slowly eat away at the materials involved. Moreover, it may be better if you could have it cleaned professionally from time to time, as mattresses are home to bacteria and germs in plenty, which might not get adequately cleansed with household cleaning products and methods.
3. Amount of Use
As you can imagine, anything that is used more will last less. However, there are two things that need to be kept in mind. Whichever type you own, it wouldn’t last as long in cases of extreme use, for example sharing couples who use for 10+ hours per day, and secondly on the other hand, if it has been left unused and uncleaned for prolong periods of time. Mattresses that are moderately used, where people sleep on it for around 7-8 hours a day, and then cleaned regularly are the ones that have the longest life.
4. The Cleaning Products
The question of how long do mattresses last really is to do with many supporting factors, but quite often depends on the cleaning methods used to clean them. For instance, in case of blood stains, you might have to use hydrogen peroxide to get rid. Too much of this chemical (and other heavy duty stain removers) would lead to a reduction of mattress life as these are not made to withstand such chemical uses.
5. Proper Precautions
It is always nice to have kids around the house. However, if your kids want to use your bed as a trampoline, it seriously isn’t a good idea. You would rather have them play elsewhere since this can seriously damage your bed. Imagine you have an innerspring, the springs will become too soft and compressed in no time at all and will leave you with a creaky and sagging surface. Additionally, whether it’s latex or memory foam, soon there will be indentations which are beyond repair. To prolong its life, you can also rotate and flip it from time to time, but that’s only if it’s double-sided and permits you to do so. You could perform this every few months for the duration of its life, which will significantly improve how long a mattress can last.
When Do You Know You Cannot Use Your Mattress?
Usually, mattresses that are over seven years old do not provide the comfort and support you need on the bed. Once you see there are signs of the surface and support wearing out, or you’re feeling uncomfortable in the bed when you are sleeping on it, you would be better off changing it. Some of the common visible signs of wearing are sagging, holes and tearing. If you cannot get a full night’s sleep and feel that you’re having a better slumber elsewhere than your bed, you need to start looking for a replacement.
You might buy the most expensive mattress, but if you do not care for it properly, it might not even last ten years. On the other side, ones which are taken care of correctly are known to last more than 15 years.

How To Get A King Size Mattress Up The Stairs
Posted in Moving on Sep 18, 2017, tagged with furniture, how to, moving tips
You’re tired of being pushed out of bed and woken up at all hours when the kids have nightmares, the dog ends up on the bed again, or your partner starts snoring, so you’ve decided to splurge and upgrade your mattress. The siren song of a better sleep has called to you, and it’s calling for a king size. After all, a bigger bed means more space to spread out on nights that feel a little too crowded. But before you take the plunge, you’ll need to figure out the answer to a simple but often overlooked question: how are you going to move your new king size mattress up the stairs?
If you’re lucky, the company you purchase the mattress from or your moving service will carry it up for you, or maybe you’ll have enough space to get it upstairs with a little pivoting and some help from good friends. But if you’re here reading this post, you are probably not one of those lucky few and are in need of a solution.
One Step at a Time
When it comes to moving a king size mattress up the stairs, there’s really only one method that works—you’re going to have to fold the mattress in half.
The good news is that folding a king mattress isn’t that difficult to do. The majority of king sized mattresses are actually hinged in the middle for this exact purpose, so they can be bent without causing damage.
To do this, use one or two ropes to tie and hold the folded mattress shut, and act as handles to help you haul it up the stairs. Once you have the mattress in place, simply reverse the fold to pop the hinges back.
If the folded mattress trick doesn’t work for you or if you seriously don’t think a folded king size mattress will fit, try getting two twin XL mattresses instead. Many people use this solution and love it. You can easily push two twins together and get a connector (aka “bed bridge”) if you have issues with the gap. Here is an example of one on Amazon.
Now the Hard Part
The box spring is a little trickier. If you haven’t purchased one yet, consider getting a split box spring. The split box spring comes in two pieces, so it’s much easier to get upstairs. If you’ve already purchased a one-piece box spring and there is absolutely no way it’s going to fit, you’re going to have to cut it in half and fold it. Here’s how to do it:
- Carefully remove the fabric from the underside of the box spring. You will see a wooden frame with several horizontal pieces of wooden strapping and a metal support bar.
- Remove the metal support bar.
- Cut the outside wooden frame where it meets the center wooden support strap, about ⅓ of the way in. Be careful not to cut the support strap – you will need it to rejoin the frame later.
- Fold the box spring in half.
- Tie it with a strong cord and transport it upstairs.
- Once it’s in the desired room, unfold it. You may need to straighten out the wires using a hammer and a thick piece of wood.
- Rejoin the wooden frame by screwing the cut portion to the center wooden support strap.
- Replace the metal support bar. You may not have the tools to do this, but if that’s the case, you can use a wooden support bar instead.
- Reattach the fabric using a staple gun.
We highly recommend you check out this how-to video from This Old House to see this method in action before trying it yourself.
Memory Foam & Foam Mattresses
If you have a memory foam or foam mattress, it can be bent in half because there’s no border rod to worry about. Actually accomplishing this, however, is more difficult than it sounds. Manufacturers use special equipment to help them compress, fold, and pack the mattresses into those small boxes, but you probably don’t have access to these tools. There are a few different tactics you can use to get your foam mattress up the stairs, but depending on how dense the foam is and what type of mattress you have, your mileage may vary.
- Roll the mattress up and secure it with ropes.
- Fold the mattress in half and secure it with ropes.
- Put it into a plastic mattress bag, vacuum seal it, and roll or fold it up.
Don’t try this alone – you will most likely need at least one or two people to help you.
|PRO TIP:Some memory foam and foam mattresses have multiple layers that can be damaged when folded for extended periods of time, so don’t store it folded for longer than necessary.|
Adjustable beds can be daunting to move, especially when they’re king sized. The base frame is typically deep and long and the mechanical parts are heavy, making it difficult to maneuver. You may be better off hiring professional movers who have experience moving bulky, heavy items.
Folding an adjustable king mattress isn’t possible, so if you’re set on moving it yourself, you’ll need the help of a few good friends. Depending on how old your adjustable bed is, it might be possible to disassemble it and move the individual pieces. Instructions should be available with the information that came with your mattress; otherwise you’ll be able to find them on the manufacturer’s website.
In the event that it isn’t possible to move the frame up the stairs, you might have to buy a new frame that separates, or opt for a box spring. Try contacting the store you originally purchased the adjustable bed from for advice and see if they offer trade-in discounts.
No matter what size bed you are considering, do you research, speak to the experts at the store you’re buying your bed from or consult your movers, and embrace what’s realistic for your current situation.

Twin Mattress Dimensions: 38” x 75”
The twin mattress size is the smallest mattress size that can accommodate young children and most adults comfortably.
Great for…children, single adults, anyone with a small living situation such as a studio apartment or shared room.
Not so great for…couples, taller adult men and women, anyone who likes to spread out when they sleep. Keep in mind that 75 inches translates to 6 foot 3.
Twin XL Mattress
Twin XL Mattress Dimensions: 38” x 80”
The twin XL mattress is the mattress you’re most likely to spot in college dorm rooms. It fits in smaller living spaces while providing extra length for taller adults or teenagers.
Great for…taller adults or teenagers in a small living situation such as a studio apartment or shared room.
Not so great for…couples, anyone who likes to spread out when they sleep.
Full/Double Mattress Dimensions: 54” x 75”
The full mattress (also known as a double mattress) provides a little over a foot more width to the bed than twin or twin XL mattresses. It used to be the standard size for couples several decades ago when homes were built smaller, but now is more commonly used for individual adults or children who can afford to have the extra space to spread out.
Great for…individual children or adults sleeping alone or with a pet, couples who like to cozy up without pets.
Not so great for…couples where one or both persons wish to have a little personal space to spread out or stretch their legs, taller adults, couples who wish to sleep with their pets.
Queen Mattress Dimensions: 60” x 80”
The queen mattress is the most popular mattress size sold today. It provides the extra length for taller adults, and the extra width so couples can still snuggle up but enjoy their personal space to stretch a bit, too.
Great for…adults living on their own who prefer to spread out or sleep with their pets, couples who like to sleep near each other without pets, smaller master bedrooms.
Not so great for…couples where both people like to really spread out or who wish to sleep with their pets.
King Mattress Dimensions: 76” x 80”
The king mattress is the same size as two twin beds side by side. This offers couples ample room to spread out, or to sleep with a large pet or children. For couples who require different support or prefer different mattress types, you can order two different twin mattresses to fit the king bed frame.
Great for…couples who like to spread out, couples who like to sleep with large pets or children, larger master bedrooms (ideally 12 x 10 square feet).
Not so great for…couples with smaller master bedrooms.
California King Mattress
California King Mattress Dimensions: 72” x 84”
The California king mattress is the longest mattress size out there (unless you order a custom mattress, of course)! This is the couple-size version of the twin XL mattress – it provides extra inches for taller adults.
Great for…taller couples who like to spread out, couples who like to sleep with multiple large pets or children, larger master bedrooms.
Not so great for…couples with smaller master bedrooms.
Crib Mattress Dimensions: 28” x 52”
Crib mattresses are designed for – you guessed it – cribs for newborns and babies. These are designed for crib frames and will last until your child meets one of the following conditions: is about 18 months old, reaches 3 feet in height, or begins escaping their crib. Search for as firm a mattress as possible. Young infants aren’t able to maneuver themselves so if the mattress is too soft and their face sinks in, they are at increased risk of SIDS or suffocation.
Great for…children up to 18 months old or less than 3 feet in height.
Not so great for…everyone else.
Toddler Mattress Dimensions: 28” x 52”
Toddler mattresses are typically the same size as a crib mattress. What’s different is that toddler mattresses are slightly softer, and are placed in toddler bed frames versus cribs. Parents can opt to buy detachable safety rails to protect the child from falling out. Some parents skip the toddler mattress altogether and move straight to a twin mattress after the crib.
Great for…toddlers or small children.
Not so great for…everyone else.
Mattress Size vs. Mattress Thickness
A common misconception is that larger-size mattresses are thicker than smaller-size mattresses. In fact, most mattress models sold today are the same thickness in each available size, even if the model is available in more than one thickness profile. For instance, let’s say a mattress model is available in 8″ and 10″ thickness options; both profiles will normally be sold in all sizes from Twin to California King.
Mattresses sold today may measure anywhere from six to 18 inches thick, but the vast majority are eight to 12 inches thick. When choosing a mattress based on thickness, your weight and your sleep partner’s weight are the most important considerations. Adult sleepers are divided into three general weight groups.
- Light (less than 130 pounds):Sleepers in this group typically prefer mattresses that are 10 inches thick or shorter. These beds offer adequate support for lighter individuals without sinking excessively. Most lighter people also have an easier time getting on and off shorter beds.
- Average (130 to 230 pounds):Those who are average weight may feel comfortable on any bed that measures eight to 12 inches thick, though most prefer those in the 10- to 12- inch range. This thickness offers a balance of conforming and support that is optimal for most average-weight sleepers.
- Heavy (more than 230 pounds):In most cases, sleepers weighing more than 230 pounds prefer beds that are at least 11 to 12 inches thick – and many may find that more than 12 inches is the best option. Thicker beds won’t sag as much beneath their bodies as thinner ones; additionally, heavier people may struggle getting on and off lower-profile beds.
One thing to note is that higher-profile mattresses tend to be priced higher than lower-profile beds. This is because thicker beds tend to contain more layers of padding and support material, including foams, latex, microcoils, and other potentially expensive components. So if you are mattress shopping on a budget, then a lower-profile bed may be the most suitable choice.
What Size Mattress Do I Need?
When choosing a mattress based on size, here are few important factors to take into account:
- Do you sleep alone or with a partner?
- What is your body type?
- Do children and/or pets frequently share your bed?
- How do you position your body when you sleep?
- How much bedroom space do you have?
- What is your mattress shopping budget?
- If shopping for a child’s mattress, how old is your child?
Generally speaking, Twin, Twin XL, and Full mattresses are most suitable for single sleepers, while Queen, King, and California King mattresses are designed for two sleepers.
It’s important to remember that Queen sizes will provide less space between the two sleepers than a King or California King will. If you and your sleep partner prefer sleeping close to one another, then a Queen will most likely work. Otherwise, a King or California King will be a better option.
By the same token, Twin and Twin XL mattresses provide less width than Full mattresses. Single sleepers that don’t like sleeping close to the edge of their bed should opt for a Full, but if this is not an issue then Twin or Twin XL sizes will suffice.
Most single sleepers will find all mattress sizes provide adequate space for them, regardless of their height or weight. However, those with larger bodies should consider mattress width. A typical Twin/Twin XL mattress measures 38 to 39 inches wide, while a Full usually measures 53 to 54 inches wide. If these dimensions are too narrow, then consider a Queen or larger.
In terms of height, a typical Twin or Full mattress will accommodate anyone who is 6 feet 2 inches or shorter; a Twin XL, Queen, or King will accommodate anyone who is 6 feet 7 inches or shorter; and a California King will accommodate anyone who is 6 feet 11 inches or shorter. Those who are 7 feet or taller may want to consider a custom bed with longer length dimensions.
If one or more children frequently sleeps in bed with you, then a Queen size or larger is usually necessary – even if you are a single sleeper and don’t have an adult sleep partner. A Full may be wide enough to accommodate you and a smaller child, but not older children and/or more than one child. If you share your bed with another adult and children visit during the night, then a King or California King will usually work best.
If you share your bed with a larger dog, then a Queen or larger may be needed – even if you don’t have an adult sleep partner. However, Twin, Twin XL, and Full mattresses may be large enough to accommodate you and a smaller dog, cat, and other smaller pets.
Do you like to sprawl out your arms and legs while you sleep? If so, then a Queen, King, or California King will be the best option – especially if you have a sleep partner. Single sleepers who tend to tuck in their arms and legs during the night may find that smaller mattress sizes are sufficient. Those who toss and turn may find smaller sizes too narrow.
Larger mattress sizes take up a lot of space. It’s important to measure the available square footage in your bedroom before choosing a mattress size. Standard square inches/footage measurements for common mattress sizes are as follows:
- Twin:2,925 sq. in./20.3 sq. ft.
- Twin XL:3,120 sq. in./21.7 sq. ft.
- Full:4,050 sq. in./28.1 sq. ft.
- Queen:4,800 sq. in./33.3 sq. ft.
- King:6,080 sq. in./42.2 sq. ft.
- California King:6,048 sq. in./42 sq. ft.
Also be sure to take the mattress height into consideration, particularly if you have low ceilings or fixtures, or you want to store items underneath the bed.
The cost difference between a Twin and a King/California King can be slight or significant, depending on the brand. Be sure to draw comparisons between the price-points of different brands while you are shopping. Also, keep in mind that Twin/Twin XL and King/California King mattresses often share the same model-specific price-points.
Crib mattresses are designed for newborns and infants up to 18 months old, as well as those whose height measures three feet or shorter. If your child is older and/or taller, then a Toddler mattress will be the most suitable option.
Mattress Size FAQ
Still have questions? The FAQ section below seeks to answer the most common questions we have received about mattresses.
Can two people sleep in a full bed?
It is not uncommon for a couple to share a full-size mattress. However, whether two people can fit comfortably on a full-size mattress may depend on the size of each individual and/or their personal sleep needs. To give you some perspective, each person will have around 27 inches of space when sharing a full bed.
What’s the difference between a full and a double?
In the mattress world, the terms “full” and “double” are often used interchangeably. “Double” is a slightly older term that is not as commonly used. It’s worth noting that a full and double are both shorter than a queen; you may want to take height into consideration when deciding between a full or queen.
What’s the difference between a twin and a single?
Much like single and double, a “twin” and a “single” are terms used interchangeably in the mattress industry, with “single” being the slightly older term.
Can you get a custom sized mattress?
The most common sizes, “king”, “queen”, “full”, and “twin” are not the only mattresses available for purchase. Many companies will make a custom mattress upon request. For example, some manufacturers will special-design an extremely tall mattress or a mattress that is larger than a California king.
Are there different sized mattresses for RVs?
Because recreational vehicles (RVs) typically feature a smaller space for sleeping, RV mattresses usually have a smaller size and lower profile. If you are searching for an RV mattress, you generally have the option to purchase a mattress that has been specially designed for an RV or a low-profile, small-size bed.
Are there any sizes larger than a California King?
Mattresses larger than the California King do exist, and are sometimes referred to as “Alaska King” or “Wyoming King” beds. The Alaska King measures at a whopping 9’ by 9’, while the Wyoming King is a slightly smaller 7’ by 7’. By comparison, California Kings measure 72” x 84”.
Alaska and Wyoming mattresses are ideal for young families who prefer to sleep together, people who share beds with large dogs, and people who simply want more space when sleeping with their significant other. You won’t find Alaska or Wyoming King beds in most retail stores; these beds typically require custom design requests.
What’s the most popular mattress size?
Capable of fitting two people comfortably, “queen” is the most popular mattress size.
Do I need sheets and a comforter that are the same size as my bed?
The short answer is yes. Particularly when it comes to fitted sheets, it is important to purchase sheets that are not only the correct size, but have the correct depth or height.The general rule of thumb is that you need a fitted sheet depth that is at least two inches deeper than the height of your mattress.
On the other hand, if you choose a mattress comforter or duvet that is slightly too large for your bed, it’s often less of a problem — the ends of the bedding may simply hang off the sides of the mattress.
Are there different sized pillows as well?
Pillow size may come into play depending on the size of your mattress. The smallest and most common sized pillows, standard (20W” x 26L”), tend to be sufficient for twin and full-size mattresses. However, people who toss and turn frequently during the night may opt for a larger pillow — such as the super standard (20W” x 28L”), queen (20W” x 30L”), or king (20-21W” x 36-41?L). You may also consider a body pillow (dimensions vary; generally between 48W” x 20L” or 54W” x 24L”), ideal for side sleepers, pregnant women, and those who enjoy snuggling with their pillow.
