Assessed from Silentnight's published specification for this mattress, captured September 2026, and from regular price comparison across our UK retail partners.
If you want something simple and honest for a child's bed, this is a sensible pick. The EcoComfort Fibres™ are breathable, which means your child is less likely to overheat, a common problem for kids who run warm at night. The open coil support system uses interconnected springs, an older but proven design that gives an even, slightly bouncy feel across the whole surface. Yes, at 17.5cm it's a shallow mattress, but for a lighter body that depth is genuinely enough. Add the foam-free, chemical-treatment-free build and the hypoallergenic finish, and it's a low-worry choice at £199, with a 60-night trial to fall back on if it doesn't suit.
Key Features & what's inside
- Sleep surface. A quilted sleep surface fabric sits on top. The quilting gives a soft, cushioned first touch before the firmer support below.
- Fibres. Breathable EcoComfort Fibres™ make up the comfort layer, which means air moves through rather than getting trapped. That helps a warm sleeper stay cooler through the night.
- Support system. An open coil traditional spring system with interconnected springs provides the support. Because the springs work together, the feel is even and slightly springy across the mattress.

Who's it NOT for?
It's a kids' mattress in UK Single only, so it won't suit adults or anyone wanting a double. At 17.5cm deep with an open coil core, heavier sleepers may find it a little too shallow and firm. And if your child prefers a soft, sink-in feel, the Medium/Firm rating may disappoint.

How firm is the Silentnight Healthy Growth Snooze Eco Comfort mattress?
Silentnight rates it Medium/Firm. In practice that means a supportive, fairly steady surface with a soft quilted top layer, rather than a plush, sink-in feel. That firmer profile generally suits children well, although a child who likes a very soft bed may take a little getting used to it.
Does the Silentnight Healthy Growth kids mattress come with a trial?
Yes. Silentnight's own site lists a 60-night trial, so you have around two months to see how your child gets on with it. There's also a 5-year guarantee for peace of mind on the build itself.
Is the Silentnight Healthy Growth mattress good for allergies?
It's listed as hypoallergenic and naturally resistant to allergens, which is reassuring for children with sensitivities. It's also free from foam and FR chemical treatments, a detail many parents specifically look for in a child's mattress.
What sizes does the Silentnight Healthy Growth Snooze Eco Comfort come in?
UK Single only. That fits its purpose as a children's mattress, but it does mean there's no option for a small double or double if you were hoping to use it elsewhere.
How long does delivery take for this Silentnight kids mattress?
Silentnight's site lists delivery within 14 days. That's slower than next-day options you'll see elsewhere, so it's worth ordering ahead if you're timing it around a new bed frame.
