Assessed from Silentnight's published specification for this mattress, captured September 2026, and from regular price comparison across our UK retail partners.
If you're choosing a first proper mattress for a growing child, this one keeps things simple. The open coil support system uses interconnected springs, which means a stable, evenly firm surface across the whole bed, helpful for children who move around at night. The EcoComfort Fibres™ layer is breathable, so warm sleepers should stay a little more comfortable. Parents worried about materials will like that it's foam free, FR chemical treatment free, and hypoallergenic with natural resistance to allergens. The 60-night trial gives you time to see how your child settles on it, and the 5-year guarantee covers a good stretch of childhood. Delivery is listed at 14 days.
Key Features & what's inside
- Sleep surface. The mattress is encased in a lightweight fabric surface. It keeps the top of the bed simple and easy-going against skin.
- Comfort layer. Breathable EcoComfort Fibres™ sit beneath the surface, which means better airflow and a cooler feel through the night. That matters for children, who often run warm while they sleep.
- Support system. An open coil traditional spring system with interconnected springs provides the support. The linked springs move together, giving a consistently firm, stable feel across the whole mattress.

Who's it NOT for?
This is a kids mattress in UK Single only, so it isn't suitable for adults or larger bed frames. The firm feel may not suit a child who prefers a softer, more cushioned surface, and at 19cm deep it's slimmer than many adult mattresses, so check your fitted sheets will sit neatly.

Yes. Silentnight offers a 60-night trial, so your child has time to adjust before you commit, plus a 5-year guarantee. Delivery is listed at 14 days.
Is the Silentnight Sleepy Eco Comfort mattress hypoallergenic?
Yes. Silentnight lists it as hypoallergenic and naturally resistant to allergens, and it's also free from foam and FR chemical treatments, which many parents will find reassuring.
What sizes does the Silentnight Healthy Growth Sleepy Eco Comfort come in?
It's available in UK Single only, listed at 90cm x 190cm with a depth of 19cm. There are no double or small double options, so it's designed purely as a child's bed.
How much does the Silentnight Sleepy Eco Comfort kids mattress cost?
It's priced from £189 for the UK Single. That's a fair price given the branded spring support, breathable EcoComfort Fibres™ and the 5-year guarantee included.
