ComfortSleep 15 Kids Mattress

The ComfortSleep 15 is an everyday foam mattress for growing children, and a sensible choice for a bunk bed or high sleeper. It has a medium feel, soft enough on top to be comfortable and supportive underneath, which suits most children from their first big bed onwards.

It's built in two layers: 5 cm of reflex foam on top for a cushioned surface, over a 10 cm foam base that keeps the support even. There are no springs, so there's nothing to creak when a child turns over. The soft stretch-knit cover comes off for washing, and a non-slip base fabric helps it stay put.

Will it fit your bed?

At 15 cm deep, the ComfortSleep suits bunk beds, high sleepers, mid sleepers and cabin beds whose maximum mattress depth is 15 cm or more, as well as day beds and ordinary single beds. On a raised bed, the maximum mattress line keeps the guard rail high enough, so always check the bed's limit before you order. Choose the size your bed asks for: a European single (90 x 200 cm) is 10 cm longer than a UK single.

It's one-sided, so rotate it head to toe regularly rather than flipping it. It arrives rolled and boxed, and reaches its full shape within 72 hours.

Most of our mattresses can be delivered the next working day (Monday to Friday, excluding bank holidays). The delivery line above shows the time for this mattress.

Some mattresses arrive rolled and boxed, which makes them easy to carry up stairs. Others arrive flat and fully wrapped, ready to sleep on straight away. The specification tells you which.

Delivery is free to UK mainland addresses, and we'll email tracking details as soon as your order is on its way. Our delivery policy covers the rest of the UK.

You have 14 days from delivery to change your mind, and another 14 days to return it. If your mattress arrives damaged or faulty, contact us and we'll put it right.

Full details are in our returns and refunds policy.

If it arrives rolled: unbox it soon after delivery, in the room it's going in. Lay it on the bed, carefully cut away the wrapping and let it unroll. You can sleep on it after a few hours, and it reaches full shape within 24 to 72 hours.

If it arrives flat: take off the wrapping and let it air for a few hours before you make the bed.

Rotate it head to toe every few weeks for the first three months, then every three months after that. Only flip it if it's two-sided. A mattress protector keeps it fresh for longer.
