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 practical for a child's bed, this is a sensible pick. The waterproof side handles accidents, and once those years pass you can flip to the quilted side. The EcoComfort Fibres™ comfort layer is breathable with an airflow border, which means less heat build-up, helpful for children who run warm at night. The hypoallergenic build and the absence of foam and FR chemical treatments will appeal if you prefer fewer treatments near your child. The Medium/Firm feel from the Bonnel open-coil springs gives even weight distribution, a good match for lighter, growing bodies. At £259 in UK Single, with a 60-night trial and 5-year guarantee from Silentnight, it's a fairly low-risk purchase.
Key Features & what's inside
- Sleep surface. Double sided, with a waterproof surface on one side and a sumptuous quilted surface on the other. You can choose the side that suits your child's stage, which is a practical touch.
- Comfort layer. Breathable EcoComfort Fibres™ with an airflow border, which means air can move through the mattress rather than getting trapped. That helps keep a warm sleeper a little cooler.
- Support system. Medium-firm Bonnel open-coil springs offering even weight distribution and support. Open coils give a slightly springier, more traditional feel than pocket springs.

Who's it NOT for?
This is a children's mattress in UK Single only, so it won't suit adults or anyone needing a larger size. At 19cm deep it's shallower than many adult mattresses, and the Medium/Firm open-coil feel may be too basic if you want pressure-relieving pocket springs or deeper cushioning.

View all mattresses
Is the Silentnight Healthy Growth Solar Eco mattress waterproof?
It has a waterproof surface on one side of its double-sided design, with a quilted surface on the other. A separate waterproof protector is available as an optional accessory for £30, but it isn't included with the base mattress.
How firm is the Silentnight Healthy Growth Solar Eco mattress?
Silentnight describes it as Medium/Firm. The Bonnel open-coil springs offer even weight distribution, which suits lighter, growing sleepers, although it may feel a touch firm if your child prefers a softer, more cushioned surface.
Does the Silentnight Healthy Growth mattress contain foam?
No. Silentnight states it is free from foam and FR chemical treatments, using breathable EcoComfort Fibres™ over open-coil springs instead. It's also hypoallergenic, which is reassuring for children with allergies or sensitive skin.
What guarantee and trial do you get with this mattress?
Silentnight offers a 60-night trial and a 5-year guarantee, with delivery listed at 14 days. That gives you a couple of months to check it suits your child before committing.
What sizes does the Healthy Growth Solar Eco mattress come in?
It's available in UK Single only, priced from £259. It measures 19cm deep, which is on the shallower side, sensible for children's beds and bunk beds.
