Rank #3 in Best Cot Mattress 2026: 10 Ranked, One Model at Two Prices
Gwydre Memory Foam Cot Mattress, 140x70x10cm
Price and rating as shown on Amazon when we collected them. Both change.
The Gwydre Cot Mattress 140x70x10cm is a cot bed mattress at £42.48, sitting third in this guide. The listing gives it 4.5 out of 5 from 245 ratings, and describes a memory foam core under a skin-friendly fibre surface, a detachable cover with a TPU backing on the reverse, and certification to BS EN 16890 and 16 CFR 1241. It is the cheapest entry in this set by a margin of several pounds, and the only one here that names a specific safety standard rather than just the word 'certified'.
The number that does not hold still is the length. The Size field, the Item Thickness field (10 centimetres), the Item Depth field (10 centimetres), the L x W x Thickness field (140L x 70W x 10Th centimetres) and the bullet text '140*70*10CM' all say 140cm. One field on the same page, Item Dimensions, reads '130 x 70 x 10 centimetres'. If the 130cm figure were the true one, the mattress would leave a 10cm gap at the end of a 140 x 70cm cot bed, so it is worth checking the listing before ordering. For what it is worth, the star-by-star breakdown supplied with the listing adds up to 100 reviews rather than the 245 ratings quoted. Everything on this page comes from the Amazon listing, not from testing we have carried out.

Questions people ask
What size cot bed does the Gwydre cot mattress fit?
The listing is sold as 140x70x10cm: the Size field reads '140x70x10', the Item Thickness and Item Depth fields both read 10 centimetres, and the bullet says '140*70*10CM'. A single field on the same page, Item Dimensions, reads '130 x 70 x 10 centimetres', which does not match the other four.
Is the Gwydre mattress waterproof?
The bullets say TPU is used on the reverse of the cover, which is described as absorbing liquid and blocking it from the inner foam, and they recommend using it with a fitted sheet. The waterproofing is in the cover backing, not the whole mattress.
How many layers does the Gwydre cot mattress have?
The listing's Number of Layers field says two. The bullets describe a memory foam core with a breathable fibre surface on top and the TPU-backed cover on the reverse.
Does the Gwydre mattress need time to expand before first use?
Yes. The listing instructs you to unzip and remove the cover and leave the memory foam flat in a well ventilated area for 24 to 48 hours until it is fully expanded.
How firm is the Gwydre cot mattress?
The firmness field says Medium. It is the only firmness figure on the page, and the listing gives no other measure of firmness.
What warranty comes with the Gwydre cot mattress?
The listing states a 10-year warranty and free replacement of non-human damage within 2 years. That is the advert's claim, not something we have tested.
