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.

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 does a mattress last?
My mattress is getting on in years. In fact, Bill Clinton was in his first term as president when I last bought a new one. Is it time for me to replace my mattress?
You’ve probably logged more than 30,000 hours in your bed, and your mattress has likely become less comfortable and less supportive. But there’s no set formula for determining when you need to replace a mattress. It might be time to buy one if:
•You regularly wake up tired or achy—you make Oscar the Grouch seem as cheerful as Mr. Rogers.
•You tend to sleep better away from home, than in your own bed. Are you planning unnecessary business trips or looking for any reason to go on a weekend getaway?
•Your mattress looks or feels saggy or lumpy—it needs go on the Abs Diet.
•You’re over age 40 and your mattress is five to seven years old. Remember, your body tolerates less pressure as it ages. As if getting older weren’t tough enough . . .
A mattress can be an expensive investment—we’ve tested models that cost in excess of $4,000—but if you treat your new one properly, it could easily last 10 years. Our advice:
•Don’t let your kids use your bed as a trampoline.
•Rotate your mattress. If you have a single-sided mattress (you sleep on only one side), rotate the mattress from end to end—that is, move the mattress 180 degrees. The foot of the mattress is now at the head, and vice versa.
If you have a double-sided mattress, rotate it as above, then turn it over so the bottom is now on top.
Perform these steps every two weeks for the first three months you have your new mattress, then once every two months thereafter. You’ll find illustrated instructions on a number of different Web sites.
• Use a bed frame that has a center support.

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.
