Why should you choose this mattress?
Most affordable children's mattresses are simple foam slabs, so the pocket spring layer here is the real draw. Each spring moves independently, which means support adjusts to where your child's body needs it rather than pushing back evenly everywhere. The memory foam layer above adds cushioning at pressure points, and the EcoFoam® core uses recycled material, a small plus if sustainability matters to you. The washable cover and hypoallergenic build make everyday life easier, and the fire resistance is certified to BS 7177 for domestic use. Add the 5-year guarantee and you have a mattress that should comfortably see a child through several years of growing.
Key features & layer details
Cover
A soft knit cover that unzips and goes in the washing machine. For a child's bed, that's arguably the most practical feature of the lot.
Memory Foam
Body-contouring memory foam that cushions pressure points, which means your child sinks in slightly at the shoulders and hips rather than lying on a flat, unyielding surface.
EcoFoam®
A recycled, sustainable foam layer giving a sturdy, medium-firm feel with pressure relief across the body. It's the supportive middle of the mattress rather than the soft top.
Pocket Springs
Springs housed in individual pockets so each one responds independently, supporting your child's body exactly where needed. This gives a more grown-up, responsive feel than all-foam children's mattresses.

Best suited for?
Children
The copy describes this as a children's mattress, with a medium firm feel that supports a growing body without feeling hard.
Allergy sufferers
The hypoallergenic build and a soft knit cover that unzips for machine washing make it easier to keep the sleeping surface clean.
Eco-conscious buyers
The EcoFoam® core uses recycled material, which is a small sustainable plus for parents who want to think about the materials in their child's bed.
Budget buyers
Most affordable children's mattresses are simple foam slabs, but this one adds a pocket spring layer, so you get more support for the money.
This is a children's mattress in a single size only, so it's not suited to adults or heavier teenagers who need a deeper, more substantial build. At 15cm it's slimmer than a typical adult mattress, and if you want a plush, sink-in feel, the medium firm surface may seem a little too supportive.
Save on an earlier or ex-display model
Some retailers still sell the earlier version of this mattress, or ex-display and returned stock at a lower price. These are the sizes where it costs less than the current model's best price.

FAQ's
How firm is the MattressNextDay Kids Hybrid mattress?
It's medium firm. That's a sensible middle ground for children: supportive enough for growing spines, with a memory foam top layer that adds cushioning at pressure points so it doesn't feel hard.
Is the MattressNextDay Kids Hybrid cover washable?
Yes. The soft knit cover is removable and machine washable, which makes dealing with spills and nighttime accidents far less stressful than sponging down a fixed cover.
How deep is the MattressNextDay Kids Hybrid mattress?
The specifications list it at 15cm deep, although one part of the product description says 14cm, so there's a slight inconsistency on the brand's page. Either way it's a slimmer profile than an adult mattress, which is normal for a children's model and works well with lower bed frames.
Does the MattressNextDay Kids Hybrid come with a guarantee?
Yes, it comes with a 5-year guarantee, and MattressNextDay offers free next day delivery. At an affordable starting price, that's reassuring cover for a children's mattress.
Is the MattressNextDay Kids Hybrid hypoallergenic?
Yes, it's hypoallergenic, which helps if your child has allergies or sensitive skin. It's also vegan friendly, made in the UK by an NBF-approved manufacturer, and fire resistant to the BS 7177 domestic standard.
