The NOFFA Soft Super King Size Mattress, model NM3-8, is a 180 x 200 x 20 cm all-foam mattress in a box, listed at £199.99 and sitting seventh in this guide. It is a three-layer build: a 4 cm gel memory foam layer, 4 cm bamboo charcoal foam and a 12 cm support foam. That works out at roughly 6.7 cm per layer — the opposite of the twelve-layers-in-22-cm arithmetic that turns up elsewhere in this round-up, where the count flatters the centimetres.

Its own ficha is one of the tidier ones here. The listing gives an item weight of 21 kg, which sits sensibly with a 180 x 200 cm foam mattress, and the three declared layers add up to the declared 20 cm thickness. That consistency is the point, because it is not universal in this set: other hybrids of a similar footprint are listed at 17 g and 454 g, and the most expensive mattress in the guide claims fewer pocket springs than one costing £143.64. Everything on this page comes from the Amazon listing itself — we have not tested this mattress.
