Why should you choose this mattress?
Washability is the standout here. Both the cover and the polyester core can be washed, so the mattress itself can recover from leaks and spills rather than quietly harbouring them. The core is breathable and stays odour free, which matters when a baby spends so many hours face-down-adjacent on it. It's tested to the highest UK standards in a SATRA approved lab, and being foam-free and FR chemical treatment-free will reassure parents who'd rather keep treatments to a minimum. It comes in Cot and Cot Bed sizes, both 10cm deep, so it can follow your child from cot to toddler bed. Delivery is stated as 14 days, so it's not one for a last-minute purchase.
Key features & layer details
Cover
A soft touch fabric with a cloud print, and it's machine washable. That means night-time accidents can go straight in the wash rather than being sponged at.
Core
A breathable polyester core that stays odour free and is itself washable. Breathability helps air move through the mattress, which is reassuring for a baby's sleep surface.

Best suited for?
Children
Made in Cot and Cot Bed sizes, both 10cm deep, it can follow your child from cot to toddler bed.
Allergy sufferers
Hypoallergenic and free from foam and FR chemical treatments, it suits households wanting to keep treatments to a minimum around a baby's sleep surface.
Budget buyers
It sits at the affordable end for a branded cot mattress, and the 60-night trial plus 5-year guarantee add a decent safety net.
Cot beds
Available in a Cot Bed size at 10cm deep, it gives a firm, breathable sleep surface that carries on as your child grows.
This is a firm mattress by design, which is right for babies but means it won't feel plush, and that's not a flaw to fix. If you want a sprung or natural-fibre cot mattress, this all-polyester design isn't that. And if you need it quickly, the stated 14-day delivery may be too slow.
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
Is the Silentnight Safe Nights Snuggle mattress washable?
Yes, unusually so. The soft touch cover is machine washable, and the polyester core itself is also washable, so the whole mattress can be properly cleaned after accidents rather than relying on the cover alone.
What sizes does the Safe Nights Snuggle come in?
It comes in Cot (60cm x 120cm) and Cot Bed (70cm x 140cm) sizes, both 10cm deep.
How firm is the Safe Nights Snuggle cot mattress?
Silentnight describes it as firm. That's what you want for a baby: a firm, flat surface supports safe sleep, even though it can feel surprisingly hard to an adult's hand.
Does the Safe Nights Snuggle have a guarantee or trial?
Silentnight's own site lists a 60-night sleep guarantee and a 5-year warranty, which is a reassuring pairing at an affordable starting price. Delivery is stated as 14 days.
Is the Safe Nights Snuggle suitable for babies with allergies?
It's hypoallergenic and naturally resistant to allergens, and it's free from foam and FR chemical treatments. The washable core and cover also help keep allergens down over time.
