Assessed from Silentnight's published specification for this mattress, captured September 2026, and from regular price comparison across our UK retail partners.
This mattress makes sense if you want something simple, breathable and chemical-conscious for a child's bed at a sensible price. The EcoComfort Fibres™ are designed for cooler sleep, which matters because children often run warm at night. The medium/firm feel gives growing bodies decent spinal support without feeling like a board. Yes, open coil springs are an older technology than pocket springs, but for a lighter sleeper on a single bed they do the job well, and they keep the £189 price honest. The 60-night trial and 5 year guarantee from Silentnight give you room to change your mind, and the foam-free build is genuinely uncommon at this level.
Key Features & what's inside
- Sleep surface. A quilted sleep surface fabric encases the mattress. Quilting gives a slightly cushioned, even feel where you first make contact.
- Fibres. Breathable EcoComfort Fibres™ sit beneath the surface, which means heat can escape rather than build up. A helpful touch for children who tend to sleep warm.
- Support system. An open coil traditional spring system with interconnected springs provides the support. This gives a uniform, slightly bouncier feel across the whole surface rather than tailored contouring.

Who's it NOT for?
It's only available in a UK Single, so couples and anyone wanting a double are out. Adults or heavier sleepers may find the 17.5cm depth and open coil springs a little basic for long-term use. And if you want deep pressure-relieving contouring, the foam-free, medium/firm build won't provide it.

How firm is the Silentnight Healthy Growth Snooze Eco mattress?
Silentnight describes it as medium/firm. In practice that means a supportive feel with a little give from the quilted surface, generally a good match for children and lighter sleepers who need spinal support without excessive sink.
Does the Silentnight Healthy Growth Snooze Eco contain foam?
No. It's built from breathable EcoComfort Fibres™ over an open coil spring system, and Silentnight confirms it's free from foam and FR chemical treatments. It's also hypoallergenic and naturally resistant to allergens.
What guarantee and trial come with the Snooze Eco mattress?
Silentnight offers a 60-night trial and a 5 year guarantee, with delivery listed at 14 days. Retailer listings also show a 5 Year Guarantee, so the cover is consistent wherever you see it advertised.
What sizes does the Silentnight Healthy Growth Snooze Eco come in?
It's available in a UK Single only, at a depth of 17.5cm. That slimmer profile suits children's bed frames, cabin beds and bunks, where a deeper adult mattress can sit too high against safety rails.
How much does the Silentnight Healthy Growth Snooze Eco cost?
It's listed from £189.00 for the UK Single. That's an accessible price for a foam-free, hypoallergenic mattress with a 5 year guarantee, helped by the simpler open coil construction.
