The Millie & Jones PocketRest 15 is our pocket-sprung mattress for children's and teenagers' beds, made with bunk beds and high sleepers in mind. It pairs individually wrapped pocket springs with a layer of high-density memory foam, so a child gets the support of springs with a cushioned surface on top.
Each spring sits in its own pocket and moves on its own. When a child turns over, the movement stays where it happens instead of travelling across the mattress, and the edges hold their shape, so a teenager who sleeps near the side still has support there. The memory foam on top moulds to the body, eases pressure at the shoulders and spreads weight more evenly. Together they give a medium-firm feel: cushioned on the surface, supportive underneath.
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 bed 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.
The stretch-knit cover comes off and goes in the wash, so accidents don't mean a new mattress. It's made in the UK and tested to BS 7177 (low hazard) by an independent UKAS-accredited laboratory. It arrives vacuum-packed, rolled and boxed, which makes it easy to carry through a doorway and up the stairs; unroll it and give it time to expand before it's slept on. It comes in single, European single, small double and double sizes, and carries a 1-year manufacturer's guarantee.

Will it fit your bed?
Choose the size your bed's page asks for: a European single (90 x 200cm) is 10cm longer than a UK single (90 x 190cm), and the Millie & Jones PocketRest 15 comes in both. On a bunk bed, high sleeper, mid sleeper or cabin bed, the bed's page gives its maximum mattress depth; at 15cm, the Millie & Jones PocketRest 15 suits any bed whose limit is 15cm or more. It comes in single, European single, small double and double; for shorty, small single, European small double and European double beds, the Millie & Jones MemoryDream 15 and ComfortSleep 15 come in all eight sizes.

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.
