Rank #7 in Best Super King Mattress 2026: 10 Ranked, One Claims 2,000 Springs
NOFFA Soft Super King All-Foam Mattress, 20 cm
Price and rating as shown on Amazon when we collected them. Both change.
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.

What buyers actually say
Quoted from customer reviews on Amazon
Verified purchase“I've had this product a little over 48 hours now and even though it's not fully inflated yet (description says maximum 72hrs), it's extremely comfortable. Material is breathable so I don't get hot whilst sleeping. The dimensions are exactly as described and the depth is very luxurious. Amazing value for what you receive. Have already recommended to family members. Extremely pleased overall.”
Verified purchase“am updating my review as the seller has taken my feedback seriously, updated the product description to better reflect the mattress, and offered a 50% refund. It wasn't the right match for us as the mattress is quite soft, but if you prefer a softer feel, it could be a good option. Thank you!”
