Assessed from Arthur Sleep's published specification for this mattress, captured September 2026, and from regular price comparison across our UK retail partners.
Choose this one if you sleep warm and want a hybrid on a budget. The cooling gel foam is there to manage heat, a common complaint with traditional memory foam, and the medium firm feel suits most back and combination sleepers, although lightweight side sleepers may find it slightly too firm at the shoulder. Starting at £219.00, it undercuts a lot of the hybrid market. Yes, the published information is sparse, but the essentials, foam comfort over springs with a temperature-focused top layer, are a sensible formula. It is currently listed with one retailer, so shopping around for a better price is not really an option here.
Key Features & what's inside

Who's it NOT for?
If you want full transparency on construction, depth or spring count before spending, this mattress makes that difficult, as the brand publishes only a basic description. It is also not for anyone who needs a stated sleep trial or guarantee confirmed up front, since neither is listed. Lightweight side sleepers may find medium firm a touch too solid.

How firm is the Arthur Sleep Cool Memory Mattress?
It is listed as medium firm, a middle-of-the-road feel with a slight lean towards support. That tends to suit back sleepers and heavier side sleepers, though lighter side sleepers may find it a little firm around the hips and shoulders.
Is the Arthur Sleep Cool Memory Mattress good for hot sleepers?
It is designed with hot sleepers in mind. The mattress includes cooling gel foam, which means the comfort layer is built to disperse body heat rather than trap it, a common issue with standard memory foam. Its hybrid build also allows more airflow through the spring layer than an all-foam design.
How much does the Arthur Sleep Cool Memory Mattress cost?
Prices range from £219 to £419 depending on the size you choose, starting at £219.00. That places it at the more affordable end for a hybrid mattress with a cooling foam layer.
What sizes does the Arthur Sleep Cool Memory Mattress come in?
It comes in five UK sizes: Single, Small Double, Double, King and Super King. That covers most bed frames sold in the UK, though there is no EU or bespoke sizing listed.
Does the Arthur Sleep Cool Memory Mattress come with a trial or guarantee?
Neither is stated on the brand's own product page, which is unusual and worth checking before you buy. If a trial period or guarantee matters to you, confirm the terms directly with the retailer you order from, as none are published.
