Why should you choose this mattress?
The springs are Mirapocket, which Silentnight says adapt to movement, so restless sleepers get support that follows them around the bed. The filling is certified British wool with antibacterial properties, and Silentnight describes it as suited to every season. It's foam-free and chemical-free, and it's hypoallergenic, which matters if you want a simpler, more natural build for a child. The waterproof finish copes with everyday spills. A medium feel is a sensible middle ground for most children, although a child who likes a very soft or very firm bed may want something different.

Best suited for?
Children
Made for children aged 3 and over, it has a medium feel and a waterproof finish that copes with everyday spills.
Allergy sufferers
Hypoallergenic and foam-free, with an antibacterial British wool filling, it gives a simpler, more natural build for a child who needs one.
Combination sleepers
Mirapocket springs adapt to movement, which means support follows a wriggly sleeper around the bed instead of working against them.
Eco-conscious buyers
The certified British wool filling and chemical-free, foam-free construction suit anyone wanting a more natural mattress for a child's bedroom.
If your child needs a mattress for a larger bed, this might not be the best choice, as it only comes in a UK single. It's rated medium, so children who like a very soft or very firm feel may not be comfortable. It's also designed for children aged 3 and over, so it isn't for younger ones.
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.
