Assessed from MattressNextDay's published specification for this mattress, captured September 2026, and from regular price comparison across our UK retail partners.
Most children's mattresses at this price 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 & what's inside
- 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.

Who's it NOT for?
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.

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 £199 for a UK single, 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.
