Where should I put my cot bed?

The position of the cot bed in your bedroom or nursery is very important.

For the first six months, experts say it’s safest for your baby to sleep in the same room as you, but after that you might want to move them to their own room.

Follow these cot bed safety tips to keep your baby as safe as possible at night.

1) Away from obvious danger

  • Avoid putting your cot bed beneath a wall-hanging frame or a mirror.
  • Keep the cot away from shelves or ledges.
  • Power cables are a strangulation hazard, even for young babies, and should be kept well out of reach.

2) Away from heat sources

  • Babies don’t need especially warm rooms, and all-night heating is rarely needed.
  • Babies should never sleep next to a radiator or in direct sunlight.
  • To keep an eye on the temperature, buy a room thermometer or get a baby monitor with a temperature display.

See more advice on ideal temperatures in our guide tosafe sleeping tips,and go to ourbaby monitor reviewsto see which monitors had an accurate temperature thermometer in our tests.

3) Away from footholds

  • Don’t leave anything in the cot, or place the cot close to another piece of furniture that could provide a foothold and allow your baby to climb out.
  • Cot bumpers, which aren’t generally recommended because of the danger of suffocation and overheating, need to be removed when your baby can get up on their hands and knees, so they can’t be used to help them climb out.
  • Make sure there are no trailing strings or cot-bumper ties, as they pose a strangulation risk.

4) Away from curtains and blinds

  • Strings and cords from curtains and blinds are another potential strangulation hazard, which need to be kept well away.
  • These can also give your baby something to hold on to and potentially help them climb out of the cot.

5) Use the base in the correct position

  • Many cots and cot beds have adjustable bases that you can move lower as your baby grows, so that he or she isn’t able to roll or climb out of the cot.
  • Make sure yours is on the correct setting, and check regularly to avoid any injuries when your baby inevitably tries to climb over the top.
  • The highest base position is only suitable for use until your baby is about three months old.
  • The lowest position is the safest, and should always be used as soon as your baby is old enough to sit up unaided – usually about eight months old.

When is it time to change from a cot to a bed?

  • Change the cot into a bed when your baby can reach over the top rail, or shows any signs of trying to climb out.
  • It’s safer to convert the cot to a junior bed so your little one can’t hurt themselves when escaping, rather than spending hours in A&E with a possible concussion.
  • The lowest side of the cot shouldn’t be lower than the shoulder height of your baby.
  • Once your baby is able to pull themself up to stand (approximately nine months old) and get their arms over the side rail, they will be able to climb out.

Are drop-sided cot beds safe?

Drop-sided cots have been banned in the US, after several children died because they became trapped between the drop side and the base of the bed.

Some people still have concerns over their safety, and the British and European safety standard has been changed to require a lock on drop sides when in the lowered position.

Our furniture-safety experts believe that this type of accident is not possible with a cot bed that complies with the relevant British standards for cots, which are different from less-stringent standards in the US.

Make sure you look out for the BS EN 716: 2005 marking if you’re buying a drop-sided cot bed. We’d also advise never leaving your child unattended in the cot when the drop side is down.

How do I know my baby’s head won’t get trapped between the cot bars?

Look for a cot bed that conforms to British Standards BS EN 716 as a cot, and BS 8509 as a bed.

The distance between each bar shouldn’t be less than 2.5cm or more than 6.5cm, so that your baby’s head can’t get trapped.

As your child gets older keep an eye out to check that the bars remain smooth and securely fixed.

What kind of cot mattress should I use?

There’s a wide variety of cot mattresses on the market, including pocket spring, foam and coir.

Whichever you go for, it’s essential to choose one that fits your cot bed correctly and that you can easily keep clean.

Go to our cot mattress reviews to see which ones passed our rigorous safety tests, and check our Don’t Buy cot mattresses to see which ones to avoid.

The Lullaby Trust recommends the following:

  • It’s very important to keep your baby’s mattress clean and dry.
  • Ideally you should buy a new mattress for each new baby because the top layer becomes less firm over time, which could pose a suffocation risk for babies under six months.
  • If you’re reusing a cot mattress, check it carefully to make sure it’s in a good condition. It needs to be flat and firm, not soft or saggy. Crucially, it needs to fit the cot without any gaps so there’s no risk of entrapment.
  • Second-hand cot mattresses should be checked carefully for any damage, for example any tears, cracks or holes. Clean and dry the mattress thoroughly, and consider buying a new cover for it or a waterproof mattress protector.

How to stop your baby or toddler falling out of a cot bed

  • You can use your cot in the highest position until your baby is three months old.
  • Change the cot base to its lowest position once your baby can sit up unaided.
  • Change the cot to a bed as soon as your toddler shows any signs of attempting to climb out.
  • Once the cot bed becomes a bed, you can buy L-shaped bed guards. The bottom part of the L slides in under the mattress while the uppermost bit sticks up, providing a soft barrier at the edge of the bed. Blow-up guards to put under the sheet are also available.
  • For a homemade solution, put a rolled-up blanket or pillow under the outer edge of the mattress to raise it slightly – your toddler will have to roll up a small incline before he or she can fall out, making it less likely.
  • Until your toddler is used to the bed, put a spare mattress, soft rug, blanket or duvet next to the bed to soften a fall if he or she does roll out.

Five tips for assembling your cot bed safely

Cot beds can be a pain to put together, even if you have more than one pair of hands and a reasonable level of DIY experience.

These top tips from our experts will help you to avoid problems when setting up your little one’s cot bed.

How to choose the best cot mattress for your baby

Preparing for a baby can be tricky. There are endless different options for even the most basic items, and cot mattresses are no exception! Here’s what you need to know about baby mattresses and how to choose the right one for your bub.

Be firm – why too soft can be dangerous

It could be a natural assumption that a nice soft mattress would be perfect for your precious baby (bed of clouds perhaps?), but that’s not actually the case. Mattresses which are too soft can in fact increase the risk of SIDS (Sudden Infant Death Syndrome). This because if a baby rolls on to their tummy, and the mattress has any soft cushioning or wave-like surface grooves, then their breathing can be obstructed.

So looking for a mattress that’s firm is very important, such as the Tikk Tokk Sweetdreams Mattress from Babies R Us. Made from pure cotton with a removable cover (handy!), it has double firmness with a ventilated inner area for airflow and overheating prevention, plus improved moisture management.

Match the size of the mattress to the cot

Don’t be tempted to use any size mattress for the cot (even if you have access to a spare one or really want to buy a particular one you’ve found). You need the mattress to meet the cot manufacturer’s dimensions, and when it does the mattress will fit snugly in the cot. This is because if you have a gap of more than 4cm between the edge of the mattress and the adjacent cot side (when the mattress is pushed to the opposite side), there is a suffocation risk again. On the flip side, if you squash a mattress that’s too small into a cot, it could bunch up – making it easier for your baby to climb out. It can also stop the drop side (if you have one) from working properly.

Quite a few reports of the mattress having a strong ‘chemical’ smell when brand new. (This could be just simply be from the manufacturing process and storage, and something that will dissipate after a short while of airing out.

Quilted Anti-Allergenic Breathable Foam Cot bed Mattress. Size: 70cm x 140cm

Super affordable, our cheapest entry in the top ten mattresses list. Don’t be put off by the price, with the huge amount of positive reviews this mattress gets, it is definitely a valid ‘value for money’ option.

Soft, supportive and anti allergenic. The core is made of foam, which is reflected in the low price. It isn’t going to last forever, but will do the job and it is replaceable after a lot of heavy use (thanks to the low price.)

The anti-allergenic properties make it safe for baby and the open cell foam structure means that when your little one is able to turn onto their tummy, the mattress will be breathable.

Kit for Kids Kidtex 70 x 140cm Cot bed Mattress – White

An affordable and well built mattress from Kidtex. We like the double cone springs combined with the foam layer. The springs ensure that the mattress gives proper postural support and increases the longevity of its use and the foam layer gives a soft and comfortable finish for baby or little one.

Finished with a water repellent outer layer that has a zip fastening for ease of use, it seems that this cot bed mattress ticks all our our checklist boxes.

Although there are no natural fabrics, this mattress has proved to be a winner by its other values, being hypo-allergenic and anti- microbial – something that is not always available in cheaper mattresses.

Everything about the Kit for Kinds Kidtex mattress is geared towards offering the most amount of quality for money and to give your little one the best sleeping environment possible.

Why we would choose this mattress:

A mattress undoubtedly created with baby and child’s needs in mind. Giving parents the peace of mind that they are giving their little ones the very best start.

Why we would not choose this mattress:

The only reason we can think of is because if contains no natural materials, they are all synthetic. However that would add a higher price tag to the mattress, so we are struggling to put it as a reason!

Baby Cot Bed Mattress – 140cm x 70cm Pocket Sprung Mattress

A great middle of the range cot bed mattress with pocketed springs for maximum comport.

The mattress has a stockinette layers, to reduce friction on the surface of the mattress making it last longer. When visible, this layer looks weird but having it there is super useful and it even makes it easier to put the outer layer back on.

There is no water repellent or waterproof layer, which is the only thing to let this mattress down.

FeaturesWhat is is made of?CleaningWarranty
Individual pocket springs for optimum comfort and support.Pocketed springsWashable removable cover with zip fasteningNone mentioned

Why we would choose this mattress:

Super comfortable and well made fore the money, To get the best of both options, breathable foam and individual pocketed springs is certainly a bonus!

Why we would not choose this mattress:

There is no water repelling fabric used, which means having to buy a separate protector.

It might also be worth mentioning that there are a couple of reviews for this mattress where buyers have complained that after taking the mattress out of the packaging for the first time, it smells of strong chemicals. But again, (like the other mattress, with the same problem reported) we think the smell may be something that disappears after being aired out.

Obaby Sprung 140x70cm Cot Bed Mattress – White

A really pretty mattress with surface detail. We love the side zip which makes washing the cover a doddle and the fact that this is first mattress we have included (in price order or cheapest to most expensive) that actually has a brushed cotton surface. We know the longevity of good cotton, wash after wash. The breathable cover also helps with air movement and heat dissipation.

The cheapest mattress we have discovered that comes with a free five year guarantee too.

We like the Obaby mattress mostly because of the high tensile coil springs, a long lasting and supportive core. That paired with a strong and soft foam layer on top and below the springs ensures the most comfortable experience possible for baby or child.

This mattress has a choice of Foam , Natural Coir, Pocket Sprung or a Spring centre.

Why we would choose this mattress:

If our child had allergies of any kind, this mattress is the most anti and hypo-allergenic focused one we have been reading about. The manufacturer even states that ‘dust mites cannot breed in this mattress’.

Why we would not choose this mattress:

There have been some reviews about the mattress not lasting for a long time, in some cases people have described this mattress as ‘poorly made and poor quality for the money’

This is certainly not the case for the vast majority, but having heard the opinions of those people, we though it was important to include that in our report.

Kinder Valley 140 x 70cm Kinder Flow Mattress

This mattress has been a long standing popular buy for parents with new babies on a budget.

It is super soft and does a great job of replicating the comfort of more expensive mattresses.

Why we would not choose this mattress:

This is a budget mattress, and if you are looking for a mattress with specialist features, such a growth support or pocket springs, this one doesn’t have any fancy features.

Mamas & Papas Sprung Cot Bed Mattress

A mattress that does everything we want it to and looks beautiful at the same time.

It is packed with luxury features and a sturdy, well built set of open springs.

When looking inside the mattress, it looks well made and very well padded with a generous layer of cushioning foam on the top and bottom.

Underneath the outer layer is a water repellent layer that can still be used even when the top layer is in the wash. Perfect for night time accidents when you and you child just want to get back to sleep!

This mattress has been designed to assist parents with babies and parents with children in different ways. One side of the outer layer has a luxurious 3D fabric, for better air circulation, breath-ability and heat distribution, (especially for babies).

The other side of the mattress actually has a waterproof fabric, especially useful when older children are toilet training, and thankfully, the waterproof surface is vapour permeable, which makes the bed significantly more comfortable for children, by reducing sweating and allowing air and heat to pass through the waterproof surface.

It also cannot be used with sleeping sensor mats or sleeping aids.

Top Budget Mattress

We are super excited about this affordable and quality mattress and think that it won’t let you down.

Top Luxury Mattress

The Little Green Sheep 70cm x 140cm Twist Natural Latex Cot Bed Mattress

We struggled to pick winner between the John Lewis one and the Little Green Sheep mattress.

At nearly half the price of the Little Green Sheep one, the John Lewis ticks all of our boxes and more. If the high cost of the Little Green Sheep one is an issue then we would certainly give our vote to the well designed, well built and great at everything John Lewis one.

However, as this is a top luxury mattress vote, we feel that what the Little Green Sheep Natural Twist combed mattress has to offer is unique, special and and investment worth making. This really is our best cot bed mattress.

It of course, ticks all of our boxes and then some.. we are astonished at the inner materials of coconut fibres and natural latex. How better to sleep than on something natural, supportive and in a pure and healthy environment, free from chemical fire retardant sprays, adhesives. (Found in almost all other mattresses) (Don’t worry, this doesn’t mean the mattress isn’t fire retardant. The wool acts as natural fireproofing.

We love this mattress so much, with all of its unique qualities. It is definitely and investment that will pay off over the years of use.

How to Choose the Right Cot-bed Mattress

How to Choose the Right Cot-bed Mattress for Your Baby

Cot-beds are extremely popular for new babies, because they give you longevity, allowing you to transition from a cot to a junior size bed when your child is ready with just a few simple modifications. However, as good as your cot-bed furniture is, you should make sure that you do get the rightCotbed Mattressfor your baby. Of course, one thing’s for sure, if you choose a cheap and uncomfortable mattress your baby might not get a good night’s sleep – as well as baby waking regularly, you don’t want to spend years getting up in the middle of the night trying to cajole your little one back into comfortable slumber.
Choosing the right type of cot-bed mattress will make all the difference, and with today’s spectacular high-end products there’s a multitude of great features to take on-board. Let Baby & Co take you through what you should look for.

Now, today’s mattresses should be safe and help prevent SIDS (sudden infant death syndrome). There are mainly four different types of mattress available for your baby’s cot bed. The reliable mattresses on Baby & Co range from £39.99 to £299.00 and come from reputable manufacturers, so there’s plenty of choice in price and definitely something to suit even the fussiest sleeper! So what should you be aware of when it comes to making your choice?

Generally, there are four types of cot-bed mattresses:

Foam Cot-Bed Mattress

Foam mattresses usually sit at the lower end of the price spectrum and represent a relatively economical buy. They are made out of a single layer of foam approximately 9cm thick which gives your baby a comfortable sleep. Foam mattresses also come with a waterproof cover. You can easily unzip and machine wash (usually at 40 degrees, some up to 60 degrees) so you’re able to keep yours nice and clean. Do wash regularly, to banish allergens and bacteria. TheBabyWise Foam cotbed mattressis made out of polyester mesh and PVC so it’s breathable too. This type of mattress is good value; however, if your baby’s room is generally in a warm area of your house, it might not be the best option as the foam tends to reatin heat and may make your baby too hot. Best to keep bed clothes lightweight if you decide to choose a foam mattress.

Sprung Cot-Bed Mattress

Sprung mattresses are made up of lots of coiled springs which fit together vertically inside the mattress. Some are covered with foam, others with felt and then there’s the fabric cover which may or may not have a wipe-clean area. Firmer than foam mattresses, they should provide your baby with good overall support. OurBabywise Sprung Cotbed Mattressis a deluxe style with high tensile coils that are designed to give your baby good comfort along with that support needed. This mattress also boasts a removable, quilted cover that is conveniently washable too so you can keep it nice and clean. It’s wise to choose a reputable manufacturer like BabyWise for sprung mattresses because you don’t want the coils to be felt through the surface of the mattress. We have plenty of other great sprung cotbed mattresses available too, all from premium manufacturers.

Pocket Sprung Cot-Bed Mattresses

Many people don’t realise that these mattresses are different to sprung mattresses. They are still made with springs, but each spring is enclosed in its own “pocket” of fabric, hence the name. They are generally the most comfortable and supportive types of cot-bed mattresses available and offer superior support for your baby. They also retain their shape, whereas some other mattresses tend to indent with time as your baby puts on weight. Pocket sprung cot-bed mattresses are more expensive than others but The Slumberland Classic Cotbed Mattress is very good value for money for a high quality pocket sprung cot-bed mattress and comes with a 2 year guarantee giving you peace of mind that it’s a good quality product. Its open coil mattress comes with additional anti-allergy technology and its cover is removable so it can easily be removed for washing. It also has a waterproof PVC layer for accidents! There is a luxury version in the form of the Slumberland Luxury Cotbed Mattress. It’s slightly more expensive than the classic and boasts responsive individual springs, an anti-allergy layer and a removable cover too. With a breathable temperature control layer and a PVC wipeable cover it’s a great all-round product.

Natural Fibres

At the higher end of the market, at £299, there’s the Boori Natural Pocket Sprung Mattress which is made out of natural fibres for supreme comfort. The cover is 100% cotton and it features a double-layer of 1000 baby sized pocket springs and 100% pure British Herdwick sheep padding so your child has the ultimate in comfort. These natural fibres allow air to circulate so your baby doesn’t perspire; they are also long-lasting and a good investment for a cot-bed especially if you want it to last your child for several years.

Cot bed mattresses (and indeed, all baby mattresses, cot and crib included) must meet the British safety standard BS 1877-10:1997. Needless to say, all the mattresses Baby & Co stock do comply. It’s important to check this out, especially if you’re buying from a different retailer.
As another word of advice, don’t re-use a mattress for a second or third baby. Always buy a brand new mattress along with a waterproof cover. This will help your baby stay protected against SIDS. We also recommend that you check your cot-bed’s dimensions so you know that the mattress will fit properly. If you would like some more information on making that all-important cot-bed mattress decision, don’t hesitate to contact one of the helpful Baby & Co advisors here.

Any sleep surface that’s too soft could increase the risk of Sudden Unexpected Death in Infancy (SUDI). But how firm should a cot mattress be? We test a range of mattresses to see if they pass the Australian standard method. We also check whether dimensions are accurate.

  • See how we test cot mattresses
  • Read our tips for buying a safe cot mattress (including how to check the firmness yourself)

We don’t just test cot mattresses, we also test prams/strollers and cots among many other products. See the Top 50 tests we conduct at CHOICE.

Until recently, there was no way of telling whether a cot mattress was firm enough to be safe for your baby. Even now, mattresses can be legally sold without officially meeting any product safety requirements. However, responsible manufacturers test their mattresses to the voluntary standard AS/NZ 8811.1:2013, which outlines a method to detect mattress firmness.

Our results show:

  • which cot mattresses passed the firmness test, which involves placing a test apparatus at various locations around the mattress (including a worst-case scenario location decided on by the tester) and seeing whether it sinks too deeply into the surface.
  • whether the claimed measurements match up with the actual measurements. We score a mattress down if the thickness is significantly more than stated, as this could end up being a fall risk depending on the depth of the cot (a cot should be a minimum of 50cm when the base is set in the lowest position, and 30cm in the upper position).

Our interactive comparison tool helps you find out which models are safe. Our Recommended list will help you see quickly which models come out on top.
