The Millie & Jones MemoryDream 15 is the mattress we recommend most often for children's and teenagers' beds. It's built in three layers: 2.5cm of high-density memory foam on top, a 2.5cm reflex foam layer beneath it, and a 10cm supportive base. The top moulds to the child and eases pressure at the hips and shoulders, and the base keeps them evenly supported. It feels soft to lie on and firm to sleep on, which is why it comes out medium-firm.
At 15cm deep, it suits bunk beds, high sleepers, mid sleepers and cabin beds whose maximum mattress depth is at least 15cm, and it's just as right on a standard single or day bed. That depth matters on a raised bed. The guard rail is designed around a maximum mattress depth, so on any bed rated for 15cm or more it stays at its full safety height.
There are no springs in it, so there's nothing to creak when a child turns over on a top bunk, and the foam absorbs movement rather than passing it on. It's made in the UK, tested to BS 7177 by an independent UKAS-accredited laboratory, and the cover comes off and goes in the wash.
It arrives vacuum-packed in a box that fits through a doorway and up a staircase. Unroll it, give it time to expand, and it's ready. It comes in eight sizes, from shorty to European double, and carries a 1-year manufacturer's guarantee.

Will it fit your bed?
Choose the size your bed's page asks for, not the size you'd guess from the frame: a European single (90 x 200cm) is 10cm longer than a UK single (90 x 190cm), and a European double is 140cm wide rather than 135cm. On a bunk bed, high sleeper or mid sleeper, the bed's page gives its maximum mattress depth; at 15cm, the Millie & Jones MemoryDream 15 suits any bed whose limit is 15cm or more. Our shorty is 75 x 175cm; if your shorty bed takes a different size, just ask and we'll help you find the right one.
Questions parents ask
Can I use it on a top bunk or high sleeper?
Yes, if the bed's maximum mattress depth is at least 15cm. The bed's page gives its maximum, and if it isn't listed, just ask and we'll confirm it.
Does the cover come off for washing?
Yes. The cover is removable and washable, so accidents don't mean a new mattress.
How does it arrive?
Vacuum-packed, rolled and boxed, so it fits through doorways and up stairs. Unroll it on the bed and give it time to expand before it's slept on.

Read more about how delivery works on our delivery information page.
Tell us within 14 days of delivery if you change your mind, then return it within a further 14 days. Return costs are yours.
For hygiene reasons we can't take back a mattress that has been removed from its sealed protective packaging, unless it's faulty. If it arrives faulty or damaged, you can reject it for a refund within 30 days of delivery.
To start a return, email support@millieandjones.co.uk with your order number. Full details are in our returns and refunds policy.
It arrives rolled. Unbox it soon after delivery, in the room it's going in. Lay it on the bed, cut away the wrapping carefully and let it unroll. Give it time to recover its full shape before you sleep on it.
Rotate it head to toe regularly so it wears evenly, and turn it over only if it's double-sided. A waterproof protector keeps it clean and fresh for longer.
