Rank #9 in Best Cot Mattress 2026: 10 Ranked, One Model at Two Prices
Opulent Home Cot Bed Mattress, 140x70x7.5cm, Waterproof
Price and rating as shown on Amazon when we collected them. Both change.
This is the Opulent Home cot bed mattress at 140 x 70 x 7.5cm, ninth in this guide and the cheapest mattress in the set at £30.99. It is also the thinnest: the mattresses near the top of this guide are listed at 140 x 70 x 15cm, and this one's size, thickness and depth fields all agree on 7.5 centimetres — even though the title sells it as 'extra thick support for newborns'.
The numbers on the listing do not all line up with each other. It carries a 4.3 rating from 46 ratings, but the star breakdown published on the same page adds up to 100: 9 one-star, 6 two-star, 3 three-star, 9 four-star and 73 five-star. The bullets describe a 'firm yet comfortable foam core', while the construction type and fill material fields both read 'ECO Friendly Fibre Core Foam Alternative', with a separate field listing a comfort foam layer. A reviewer also describes buying a 15cm thickness, which is not what this listing sells. Everything below comes from the Amazon listing for this product, not from any test we have carried out.
