Assessed from Silentnight's published specification for this mattress, captured September 2026, and from regular price comparison across our UK retail partners.
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 & what's inside
- 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.

Who's it NOT for?
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.
Silentnight Safe Nights Snuggle Breathable Cotbed Mattress
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, priced from £99 to £109.
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 this 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.
