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.
