Watch for tips on what to look for when choosing a cot bed, including types of wood, size and more. 

Should I choose a cot bed or a cot? 

Once your baby grows out of a Moses basket or bassinet, which most parents use for a newborn, he or she will need to move into a cot or cot bed. There are pros and cons of each.

Cot beds

  • A cot bed is a cot with removable sides and a removable end panel that can be converted into a toddler-sized bed.
  • An old-fashioned crib or cot is soon outgrown. The big advantage is that a cot bed will last you longer than a cot because it is used both as a cot and as a junior bed. 
  • Most cot beds will last until a child is nine years old. But this will depend on the weight of your child, and how much wear and tear they put the bed through.
  • Cot beds we've tested start from just over £100 and go up to more than £700.
  • Cot beds are larger than cots – generally around 70cm wide – so they give your baby a bit more space to roll about and stretch their arms, but they’re not necessarily much more expensive.
  • If you have the space, it might make sense to buy a cot bed from the outset, as it will last longer and you can avoid the hassle of having to buy two separate pieces of furniture.

See those we recommend in our cot bed reviews.


  • Cot prices start at around £70 for a basic cot, up to around £700 for a luxury solid oak model.
  • Cots are generally smaller than cot beds – around 50-60cm wide – so if your baby’s bed will be in your room until he or she is six months old, as is the current advice, a cot may fit more easily if space is limited.
  • Sizes do vary, though. Cots designed to fit 'standard-sized' cot mattresses are a few centimetres narrower than cots designed for 'continental-sized' mattresses, although they're often a similar length (around 140cm). Measurements should be clearly displayed on the cot label.
  • You can buy bedside cots with a removable side so you can position the cot right next to your bed. The base can be adjusted so your baby’s mattress can be lined up with yours, which makes night-time feeding easier.
  • If you’re planning on more than one child with a small age gap between them, a cot may be more suitable, as you’ll more than likely use the cot for the new baby and buy a single bed for your older child.

Cot and cot bed types 

You can deviate from a standard cot or cot bed – rectangle shape, fixed sides – and choose to go for a drop-sided or sleigh cot or cot bed. You can also choose a cot or cot bed that comes with a drawer or storage built in.

Drop-sided cot beds and cots

Some cot beds and cots have one side rail that can be dropped down to give better access for getting your baby in and out. 

Drop-sided cot beds and cots are particularly useful if you are short or slightly bulkier as the drop side makes it easier for you to get your baby in and out. 

There are different ways to lower the drop side. Some drop-sided cots and cot beds come with a nudge and lift mechanism: helpful because it can be operated with one hand while you've got your baby in the other hand. Others can have catches, a trigger mechanism or a foot pedal. 

There has been some controversy over drop-sided cots in the USA. Read our guide to using cot beds safely.

The drop side and the back rail are usually removed when you convert a drop-sided cot bed into a junior bed. 

Sleigh cot beds and cots 

Sleigh cot beds are popular with parents. They're named sleigh cot beds because of their wavy design which makes them stand out from other cots and cot beds with their all-straight sides. 

When you're buying, check that the sleigh-shaped ends, which are usually bolted either side of the head and foot boards, do not create a dip or groove between the pieces of wood where your baby's clothing could get caught. 

Sleigh cot beds can be either drop sided or have fixed sides. The side rails will be removed to turn them into a bed.

Cot beds with drawer

Some cots and cot beds utilise what's essentially dead space beneath the base and the legs to include a drawer.

A cot bed with a drawer might be ideal for you if your baby's nursery is small and lacks storage space. 

You can also get sleigh cot beds and cots with drawers. 

Cot bed and cot sizes 

If space it limited, you may decide that the better option is to go for a cot.  A cot is the smaller of the two, measuring approximately 124 x 64cm.  

Cot beds come in different designs, so size can vary but on average the size of a cot bed tends to be around 145 x 75cm.

Things to check before you buy 

1. Height-adjustable base

Most cots and cot beds have a base that can be adjusted as your baby grows, usually with three positions. 

When your baby is small, the mattress sits on the highest base level for the first few months, so you can lift your baby in and out easily. The instructions usually recommend that the lowest position is the safest and should always be used as soon as your baby starts to move about a bit and pulls themselves up, which can be about eight months old. 

You may think it is pointless going for a three-position cot bed in this case, but it's normal to use the second height position for the bed mode, as the lowest one can be a bit low for a bed. With a choice of several heights, you can adjust the bed to suit your child, however old they are.

2. Cot mattress

Don't forget, whatever bed you go for, it's crucial to get the right type and size of mattress to go in your chosen cot or cot bed.

The Lullaby Trust, which promotes advice on safer sleep for babies, recommends that you buy a new mattress or, if using a used mattress, carefully check that it is clean, dry and free from cracks or tears beforehand. Your mattress should be firm, with no sagging, and should fit the cot or cot bed snugly with no gaps.

Read more safe sleeping tips in our dedicated guide.

Mattresses are normally sold separately from a cot or cot bed, giving you a choice of different types, but the manufacturer will make recommendations for the size of mattress you should use.

3. Size

Cot beds are generally bigger than a cot, and although there is a lot more variation in sizes, most cot beds are quite similar, which is about 146cm long and 77cm deep, and somewhere between 90cm and 105cm tall at the head end. Cots are generally around 50-60cm wide and 140cm long.

Most cot beds have side rails that are around 84-87cm high in the highest position, which makes them challenging for shorter people to reach over to lay a sleeping baby down. A cot bed with a drop side will reduce this height, making it easier to reach your baby when the base is on the lowest position.

Double check the cot bed you choose will fit in your bedroom (where your baby is meant to sleep for the first six months), as well as where you plan on having it the nursery.

4. Teething rail

A teething rail protects your cot bed and your toddler from damage caused by each other. Chomping on the edge of a cot is a habit many teething babies relish. Choosing a cot with a teething rail – a protective covering on the side-edges of the cot – helps to avoid cot bed damage.

5. Casters

Some cots have casters or mounted wheels – handy if you want to move it into a different room. It also makes for easier cleaning under and around the cot.

6. Colour

White and grey are the two most popular colours if you don't want to go for a standard wooden finish cot bed but you can also get blue and pink cot beds and a host of other colours. 

7. Wood or not?

Check whether the cot or cot bed you're buying is made from wood or mdf. You'll generally pay more for a wooden cot bed than for MDF. But expect to pay more or less depending on the different types of wood: for example a plywood cot or cot bed will cost less than one made from real mahogany. 

Remember also to check whether the 'mahogany' on the label is real mahogany or a finish on top of MDF. 

Secondhand cot safety 

When it comes to the safety of your baby, you can never be too careful. Especially when creating a safe sleeping space.

Buying second-hand could save you some cash, but there are some essential safety tips to read if you are thinking of doing this, or you're getting one from friends, or are even tempted to use an old family heirloom.


  • Get a copy of the original instructions. Many can be downloaded from the internet.
  • Buy a new mattress for the cot.
  • Check whether the cot conforms to British (BS EN 716-1:2008+A1:2013) or European safety standards – look in the instructions for a BS number or check for markings on the cot itself.
  • Make sure it's in a good condition and nothing is broken or worn out.
  • Measure the bar spacing: the bars should be no more than 6.5cm apart, so your baby can't get stuck between them.
  • Check that there is at least 50cm between the top of the mattress and top of the cot.
  • Check there are no protrusions on the top rails where your child could catch his or her clothing, or get anything caught around his or her neck.
  • Check that the drop-side mechanism works smoothly and stays reliably in the ‘up’ position.
  • Check that the drop-side is secure and can't be lowered by a child.
  • Check there are no footholds or cut-outs or ledges in the sides or the ends that could help a baby climb out.
  • Make sure that the mattress is the right size – there should not, at any point, be a gap of more than 3cm between the mattress edge and the cot.
  • Remove any transfers on the inside of the cot because they could come off and become a choking hazard.


  • Accept a cot unless it comes with the original instructions, or you can obtain a copy of the instructions from the manufacturer; they contain important advice for using the cot safely.
  • Use an old family heirloom, as it probably won’t meet current safety standards.
  • Use a worn, dirty or damp mattress.
  • Choose a mattress with handles – they may trap your baby's hands or feet.
  • Stick decorative transfers and labels on the inside of the cot or anywhere else your baby can reach.

Travel cots 

Travel cots are portable cots that you can fold up and put in a bag to take away with you. Most have a plastic or metal frame, woven fabric and mesh sides, and a hard segmented bottom with a folding, lightly padded mattress.
