Why should you choose this mattress?
The Jay-Be QUEST Q3 is a children's hybrid with a soft knitted fabric surface and pocket springs, so it gives a child a springy, supportive feel rather than a sink-in one. The firmness is described as soft to medium, which suits most children, although a child who likes a really firm bed may find it too gentle. It's described as breathable and hypoallergenic, and the stretch knit fabric is recyclable, which will appeal if you want a greener choice. It arrives vacuum packed and rolled, so it's easy to get up the stairs. Jay-Be backs it with a 5-year guarantee, and it comes in UK Single only.
Key features & layer details
Soft knitted fabric surface
A soft knitted fabric cover that is kind to the skin. It gives your child a cosy surface to sleep on, and the stretch knit fabric is recyclable.
Micro e-Pocket springs
A layer of small micro e-Pocket springs sits above the main core. They give continuous, huggable support and comfort, so the bed feels cushioned without being sink-in soft.
Deep e-Pocket core
The deep e-Pocket springs form the base of the mattress and carry the support. They work with the micro springs above to hold your child up while they sleep.

Best suited for?
Children
Sold as a children's mattress in UK Single, which suits most children's beds and means it should fit a standard single frame.
Eco-conscious buyers
Named as an eco-friendly mattress, which gives parents who want a greener choice for their child's bed a reason to look closer.
It's only available in UK Single, so it won't work if your child sleeps in a small double or you want a matching adult size. And because we can't yet verify its firmness or build details, cautious buyers who like to compare specs line by line may want to wait or ask the retailer directly.
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.
