Why should you choose this mattress?
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 an affordable starting price, with a 60-night trial and 5-year guarantee from Silentnight, it's a fairly low-risk purchase.
Key features & layer details
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.

Best suited for?
Children
The waterproof side handles accidents and the quilted side can be used later, so one single mattress covers different stages of growing up.
Warm sleepers
Breathable EcoComfort Fibres™ with an airflow border let air move through the mattress, which means less heat build-up for children who run warm at night.
Allergy sufferers
The hypoallergenic build and the lack of foam and FR chemical treatments suit anyone who prefers fewer treatments near a child's bed.
Lighter sleepers
Medium/Firm Bonnel open-coil springs give even weight distribution, which suits the lighter, growing bodies this mattress is designed for.
Budget buyers
An affordable starting price, a 60-night trial and a 5-year guarantee make this a fairly low-risk purchase for a child's bed.
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.
Save on an earlier or ex-display model
Some retailers still sell the earlier version of this mattress, or ex-display and returned stock at a lower price. These are the sizes where it costs less than the current model's best price.
