Why should you choose this mattress?
The open springs are built to support growing bodies, and the recycled fibres on top add a cosy layer of comfort. The waterproof inner lining protects against spills and accidents, and the outer cover goes in the washing machine, so day-to-day mess is easy to deal with. The knitted surface is hypoallergenic and gentle on skin, which helps if your child has sensitive skin. It's also free from foam, chemicals and PVC. A sensible, practical choice for a child's bed, although it's a simple build without extra comfort layers.

Best suited for?
Children
Open springs built to support growing bodies and a waterproof inner lining that copes with spills and accidents make this a practical choice for a child's bed.
Allergy sufferers
The hypoallergenic knitted surface and the lack of foam, chemicals and PVC give a gentler sleeping surface for anyone wanting to avoid common irritants.
Eco-conscious buyers
Soft recycled fibres sit above the springs for cushioning, and the mattress is free from foam, chemicals and PVC, so it avoids those materials entirely.
European bed frames
Sold only as a 3'0 Euro single, 90 x 200cm, it is made to fit frames of that length, so there is no sizing guesswork.
If you want a deep, plush mattress with contouring layers, this might not be the best choice. At 14cm it's slim, and the comfort comes from open springs and recycled fibres rather than foam. It's also sold only as a 3'0 Euro single, 90 x 200cm, so check your bed frame takes that size.
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.

FAQ's
How firm is the Little Big Dreams Growing Support Traditional Spring Moon Mattress?
Little Big Dreams doesn't publish a firmness rating for this mattress. It uses traditional open springs with a layer of soft recycled fibres on top, so check the feel with your child if you can.
What size is the Little Big Dreams Growing Support Traditional Spring Moon Mattress?
It's sold as a 3'0 Euro single measuring 90 x 200cm. That's a different length from a standard UK single, so measure your bed frame before you order.
How deep is the Little Big Dreams Growing Support Traditional Spring Moon Mattress?
It's 14cm deep. That's a slim profile, which suits many children's beds, although it won't have the thick, cushioned feel of a deeper mattress.
Is the Little Big Dreams Growing Support Traditional Spring Moon Mattress waterproof?
It has a waterproof inner lining against spills and accidents, and the outer cover is machine-washable. That makes it a practical pick for younger children, though the lining sits inside the cover rather than on the surface.
Does the Little Big Dreams Growing Support Traditional Spring Moon Mattress come with a trial?
Dreams offers a 100-night comfort guarantee on it. That's the retailer's own offer rather than the manufacturer's, so check Dreams' terms before you buy.
