Assessed from Arthur Sleep's published specification for this mattress, captured September 2026, and from regular price comparison across our UK retail partners.
The main draw here is value. A pocket-sprung hybrid with gel foam from £319 is genuinely affordable, and the gel layer is there to help disperse warmth, which matters if you tend to sleep a little hot on all-foam beds. The 800 pocket springs move independently, which means less motion transfer than an open-coil mattress when a partner shifts about. Arthur Sleep offers free next day delivery, a 60-night trial and a 10-year guarantee, which is decent reassurance at this price. It is hypoallergenic too, a small but welcome point for allergy-prone sleepers. The spring count is modest, but for lighter and average-weight sleepers it should provide adequate support.
Key Features & what's inside
- Comfort Layer. A combination of gel foam and comfort foam sits at the surface, which means gentle pressure relief with the gel working to draw heat away from you. It gives the mattress its medium feel.
- Support System. Beneath the foam sit 800 pocket springs, each moving independently, which means the mattress responds to your shape rather than the whole surface dipping. This also helps limit disturbance from a restless partner.

Who's it NOT for?
Heavier sleepers may find 800 pocket springs a little light on support over time, and anyone who prefers a distinctly firm or distinctly soft surface should look past this medium feel. It's also not for you if you want natural materials, as the fillings here are synthetic foams.

How firm is the Arthur Sleep Gel Arthur mattress?
Arthur Sleep describes it as medium. That middle-of-the-road feel suits most back and side sleepers, although lighter side sleepers may find it slightly firmer than expected, and dedicated stomach sleepers who like a firm surface may want more resistance.
Does the Gel Arthur mattress come with a trial period?
Yes. Arthur Sleep offers a 60-night trial when you buy direct, so you can sleep on it at home before committing. It also comes with a 10-year guarantee covering manufacturing faults.
Is the Gel Arthur mattress good for hot sleepers?
It should help. The comfort layer uses gel foam, which is designed to disperse body heat, and the 800 pocket springs allow more airflow than an all-foam design. If you sleep very hot, no foam-topped mattress is entirely immune, but this is a sensible budget option.
How deep is the Arthur Sleep Gel Arthur mattress?
It is 27cm deep, which works with most standard fitted sheets. That depth comes from gel and comfort foam layers over an 800 pocket spring support base.
What sizes does the Gel Arthur mattress come in?
It is available in UK Single, UK Double and UK King, priced from £319 to £499 depending on size. Arthur Sleep offers free next day delivery.
