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
All six listings state a depth, and four state a firmness: Medium Firm on both Vesgantti and the slily, medium soft to soft on the Wilson Beds. The Simba and Nectar listings name their layers but give no firmness rating, and the slily and Wilson Beds listings state no warranty term.
Our Take
As a default, pick the Vesgantti Double Hybrid: Medium Firm, 135x190x26cm, CertiPUR-US & OEKO-TEX certified materials, a 100-night trial and a 10-year warranty, all on the listing. For a king size bed, the Simba Hybrid Pro lists 150 × 200 cm and two layers of Aerocoil microsprings, and the Nectar Hybrid Lite a 365-night home trial and a Forever Warranty.
