Assessed from Silentnight's published specification for this mattress, captured September 2026, and from regular price comparison across our UK retail partners.
The main appeal here is that it's designed around children rather than being a scaled-down adult mattress. The 600 Mirapocket® springs adjust individually to body weight, which means a lighter child still gets support that responds to them rather than a surface that barely registers they're there. The EcoComfort Fibres™ top layer is breathable, helpful if your child runs warm at night. The foam-free, FR chemical treatment free build will matter to parents who'd rather keep chemical treatments out of the bedroom. Add Silentnight's 60-night trial and 5-year guarantee, plus delivery in 14 days, and the £239 price feels justified for a mattress that should see a child through several years of growing.
Key Features & what's inside
- EcoComfort Fibres™. A breathable comfort layer designed for cooler sleep. It sits at the top of the mattress, which means less heat trapped around your child overnight.
- Mirapocket® springs. 600 Mirapocket® springs provide full body support, with each pocket spring adjusting individually to body weight. The zoned design means support goes where it's needed as your child moves around.

Who's it NOT for?
It's only available in a UK Single, so it won't suit older teens ready for a double or anyone furnishing a guest room. Adults should look elsewhere too: this is built for children's lighter bodies. If your child strongly prefers a very soft, sink-in feel, the medium support here may feel a little firm to them.

Is the Silentnight Healthy Growth Dreamer suitable for a child with allergies?
It should be a sensible choice. The mattress is hypoallergenic and free from foam and FR chemical treatments, according to Silentnight, which makes it a reassuring option for children with sensitive skin or allergies. If your child has a diagnosed allergy, it's still wise to check the specifics with your GP.
How firm is the Silentnight Healthy Growth Dreamer kids mattress?
Silentnight describes it as medium. That's a balanced feel for a growing child: supportive enough for developing spines, with the 600 individually adjusting Mirapocket® springs responding to lighter body weights, but not so firm that a small child feels like they're sleeping on a board.
Does the Silentnight Healthy Growth Dreamer come with a trial period?
Yes. Silentnight offers a 60-night trial, so your child can sleep on it at home before you commit fully. It also comes with a 5-year guarantee, which is reasonable cover for a mattress likely to be replaced as your child grows anyway.
What sizes does the Silentnight Healthy Growth Dreamer come in?
It's available in a UK Single only, priced at £239. That suits most children's beds, but if you're after a small double or larger for an older teenager, you'll need to look at a different model.
How deep is the Silentnight Healthy Growth Dreamer mattress?
It's 21.5cm deep. That's a practical depth for children's bed frames, including bunk beds and mid-sleepers, though you should check your frame's maximum mattress depth before buying, especially for bunks with safety rails. Standard single fitted sheets should fit without trouble.
