What are the best memory foam mattresses to buy in the UK?

The Uliyati King Size Gel Memory Foam Mattress suits a king size bed where documented construction matters: the listing states four foam layers in 20CM, CertiPUR-US and OEKO-TEX materials, a 100-night trial and a 10-year warranty.
The Uliyati King Size Gel Memory Foam Mattress is our top pick for the best memory foam mattress in the UK because its listing breaks its 20CM depth into four foam layers and states CertiPUR-US and OEKO-TEX certified materials, a 100-night trial and a 10-year warranty. For a king size hybrid, the CBAEC-RSN King Size Memory Foam Hybrid lists a gel-infused memory foam top layer over independent springs and also states a 10-year warranty. For a double, the TeQsli Memory Foam Spring Hybrid states 27CM, a 7-zone pocket spring system and CertiPUR-US certified foam.

Stated depths run from 20cm (Uliyati and Twirest) to 27cm (TeQsli). Two are king size, three are double and one is single.

Our process
How do we choose our picks?
We don’t lab-test products ourselves. Instead we synthesise current Amazon UK listings and published specs into clear, honest recommendations. We earn a commission if you buy through our links, but that never changes which products we rank.
Current UK availability
We check each pick against live Amazon UK catalogue data rather than last year’s model lists. Stock moves fast, so a listing can sell out after we publish.
Published specs
We compare manufacturer specifications so each pick is right for a real budget and use-case.
UK-specific fit
We factor in UK voltage and plug/fitting standards — details that generic global lists miss.

Editor's Note
Only the Uliyati listing gives a layer-by-layer breakdown with a thickness for each foam layer. Two listings state a warranty term, Uliyati and CBAEC-RSN, both 10 years; the other four do not mention one. Three listings name a foam or fabric certification (Uliyati, CBAEC-RSN and TeQsli), and the CBAEC-RSN is the only card that does not state a firmness.
Our Take
As a default, choose the Uliyati King Size Gel Memory Foam Mattress: its listing gives four foam layers, CertiPUR-US and OEKO-TEX certified materials, a 100-night trial and a 10-year warranty. For a king size hybrid, the CBAEC-RSN also states a 10-year warranty and CertiPUR US and Oeko-Tex Standard 100 certification. For a double, the TeQsli lists 27cm, 7-zone pocket springs and a 100-night trial.
