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.

Questions parents ask

Can I use it on a top bunk or high sleeper?

Yes. The stretch-knit cover is removable and washable, so accidents don't mean a new mattress.

Yes. The Millie & Jones PocketRest 15 meets BS 7177 (low hazard), tested by a UKAS-accredited laboratory.

Size guide

Measure the inside of your bed frame, width and length, then find the matching size. Go by the frame, not your old mattress, as mattresses flatten and spread over the years.

Size Centimetres Feet and inches Good for

Bunk beds, high sleepers and cabin beds have a maximum mattress depth. Check it on the bed's page and choose a mattress that's the same depth or less.

Some shorty beds take a 70 x 160 cm mattress rather than 75 x 175 cm, so check your bed's mattress size before you order.

I chose the middle priced mattress as the beds will only be used when our grandchildren visit in the holidays. The mattresses have been christened this week and were given the thumbs up!

Wrong size sent and a nightmare trying to get it returned logistically

Hi Liz,

We sent the wrong size, and I'm sorry for the run-around getting it collected. Once it was clear a collection wasn't going to work for you, we sent the correct mattress and told you not to worry about returning the other one.

That's now how we handle replacements on anything awkward to send back. The customer keeps the original and we sort the rest.

Kind regards,

Millie & Jones
