Price and rating as shown on Amazon when we collected them. Both change.
The Tegeniss King Size Mattress is a 25 cm hybrid — memory foam over pocket springs — sold in a box for £170.99 and rated 4.6 out of 5 from 73 ratings on Amazon. It takes eighth place in this guide to king size mattresses.
What stands out about this listing is not a mistake but the absence of one. Four other entries in this guide contradict themselves on the measurements a buyer actually compares with: one lists a hybrid with 'Number of Mattress Coils: 7', one gives thickness as '26 Picometre' in one field and 26 cm in another, one writes 150x190 cm in the text and 150x200 cm in the size field, and one gives '200 x 30 x 150 centimetres' with a 30 cm width. The Tegeniss states the same mattress four different ways — 5FT King (150 x 200 x 25 cm), 200 x 150 x 25 centimetres, 2L x 1.5W x 0.25Th metres, and 25 cm of thickness — and all four agree. The only figure that needs a second look is the star breakdown, which runs to 100 across the bands while the headline covers 73 ratings. Everything on this page comes from the Amazon listing as published, not from any test we ran.

Questions people ask
What size is the Tegeniss YQ-UK-SM mattress?
The listing gives it as 5FT King (150 x 200 x 25 cm) and, in a second field, as 200 x 150 x 25 centimetres — the same three numbers, with length and width the other way round.
How firm is it?
The Tegeniss listing describes the mattress as medium firm, combining mixed independent bag springs with pressure-reducing cotton and memory foam.
Do I need to wait before sleeping on it?
Yes. The listing asks for 72 hours after opening the box so the mattress can fully stretch, which it says helps durability and comfort.

It is listed as both: coil type is pocketed coil and construction type is spring system, with memory foam and cotton as the fill and memory foam as the comfort layer, across 3 layers.
How much does it weigh and how does it arrive?
The Tegeniss is listed at 25 kg and arrives vacuum-compressed, sealed and rolled into a box.
