Skip the Little Big Dreams Growing Support Traditional Spring Kids Moon Mattress unless it's genuinely cheap in a sale; even then, I prefer the pocket-sprung options in the same range for your child's everyday bed. The firm feel and washable, waterproof arrangement have their uses, especially if accidents are still part of bedtime. But you're buying an open-coil mattress underneath those practical layers, and I wouldn't choose that construction for a child's main bed.
The waterproof lining is the bit I like most, which tells you where this mattress is strongest: dealing with the aftermath of bedtime, possibly involving a cup you specifically said to leave downstairs. Cleaning matters, but so does what your child sleeps on every night. A washable cover is helpful; it isn't enough to make me overlook the springs.
The firm, foam-free build uses linked springs
You can expect a firm, springy surface with some softness from the fibre layers, without the slow sinking feel of memory foam. This mattress has traditional open-coil springs beneath soft recycled fibres, with a knitted outer cover. For a child who likes a solid surface, that straightforward feel has appeal. There's no need to make a children's mattress sound like equipment for a space mission.
The issue is how the springs respond. Open-coil springs are linked, so pressure on one part of the mattress affects a wider area. Pocket springs sit in individual fabric pockets and respond more separately beneath the body. I prefer that more local response for an everyday bed: the surface can give beneath a shoulder or hip without pulling as much of the surrounding spring unit down with it.
Firmness alone doesn't settle this comparison. A mattress can feel solid when you first lie down yet have less give where you need it. Here, the fibres provide the cushioning over a firm spring unit, so expect your child to lie more on the surface than sink deeply into it. If they already dislike a hard bed, this is the wrong direction to take.
The outer cover comes off for machine washing, while a waterproof inner lining protects the fillings from spills and accidents. That's a sensible separation: you can wash the outer fabric while keeping liquid away from the inside. The washing machine gets the unpleasant job, which seems a fair division of labour. For a parent choosing between otherwise similar mattresses, this arrangement is a real advantage; against a better spring construction, I still put the springs first.
The clean-up features appeal more than the open-coil support
This mattress has the most appeal if you want a firm children's bed with straightforward accident protection, but the pocket-sprung alternatives remain the better everyday choice to my mind. Owners mostly call it comfortable, and several say their child sleeps well on it. Some call it good value. The firm feel divides them. One owner found it "slightly too hard for my son" and exchanged it, while another wrote "Very hard mattress, not comfortable at all." Others like that same firmness, "A great firm mattress for my 5 year old", and a few mention the washable cover: "Handy the cover comes off and can be washed". Those are the two positives I take seriously here because they match the construction.
Comfort comments are personal, especially with firmness. A child who enjoys a solid bed can be comfortable on a surface another child finds unforgiving. My habit is to read the middling reviews as well as the enthusiastic ones: a happy bedtime report is lovely, but it's hardly going to include a detailed discussion of linked springs. Look for comments about the same model and how the child gets on with its firm surface.
The waterproof lining also matters more for some households than others. If accidents are frequent, protecting the fillings and being able to wash the cover are practical reasons to pay attention. If that stage has passed, you have less reason to favour this mattress over a pocket-sprung option. An emergency juice defence system is useful, but it needn't be the main reason you choose a bed.
These are the people I would steer elsewhere, even if the removable cover looks convenient:
- Your child dislikes a firm surface. The soft fibre layers sit over a firm spring unit. Choose a mattress with more cushioning if the current complaint is that the bed feels hard.
- You want springs that respond separately under the body. This mattress uses a linked open-coil unit. A pocket-sprung model is the more suitable construction.
- You're considering it without a substantial sale saving. The same range includes pocket-sprung options I rate more highly. Compare those before paying for the convenience of the washable cover here.
A pocket-sprung Little Big Dreams mattress is the better step up
Choose one of the pocket-sprung Little Big Dreams variants for your child's main bed, particularly if the price difference is modest. You get springs that respond more separately, which matters more to me than having an especially tidy laundry plan. For a child who finds firm beds uncomfortable, choose a pocket-sprung option with a softer comfort layer as well; there's no medal for tolerating the hardest surface. Check the alternative's washable-cover and waterproof details before buying, because those are the useful features you might otherwise lose.
