DryComfort 15 Waterproof Kids Mattress

The DryComfort 15 is a foam mattress with a waterproof cover, for the nights that don't go to plan: potty training, bedwetting, spilled drinks or a poorly tummy. Liquid stays on the surface instead of soaking into the foam, so you can wipe it down, change the bedding and get everyone back to sleep.

Under the waterproof cover it's built like our ComfortSleep 15: 5 cm of reflex foam over a 10 cm foam base, with no springs, for a medium feel that suits growing children. The cover comes off for washing. It's just as useful in a guest room, a student let or anywhere you'd rather not worry about the mattress underneath.

Will it fit your bed?

At 15 cm deep, it 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 standard single beds. Check your bed's maximum before you order, because the guard rail is designed around it. A European single (90 x 200 cm) is 10 cm longer than a UK single, so choose the size your bed asks for.

It's one-sided, so rotate it rather than flip it. It arrives vacuum packed, rolled and boxed; allow up to 72 hours for it to reach its full shape.

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.
