Arthur Sleep Gel Arthur Mattress
The Gel Arthur from Arthur Sleep is a medium-feel hybrid that pairs gel foam comfort layers with 800 pocket springs, which means you get some cushioning at the surface without losing the supportive, slightly bouncier feel that springs bring.

At 27cm deep, the Gel Arthur sits comfortably under standard fitted sheets. It comes in Single, Double and King sizes and sits firmly in budget-hybrid territory. You also get a 60-night trial and a 10-year guarantee from Arthur Sleep, so there is a reasonable safety net if the feel isn't right for you. It suits most average-weight back and side sleepers, although anyone wanting a very firm surface should look elsewhere.

Why should you choose this mattress?
The main draw here is value. This pocket-sprung hybrid with gel foam 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 for the 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 & layer details
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.

Best suited for?
Back sleepers
The medium feel from the gel and comfort foam layer, over 800 pocket springs, gives average-weight back sleepers balanced support without a hard surface.
Side sleepers
Gentle pressure relief from the gel foam and comfort foam at the surface suits average-weight side sleepers who want some cushioning.
Couples
Each of the 800 pocket springs moves independently, which means less motion transfer than an open-coil mattress when your partner shifts about.
Warm sleepers
The gel layer is there to help disperse warmth, which suits anyone who tends to sleep a little hot on all-foam beds.
Budget buyers
Described as genuinely affordable, this pocket-sprung hybrid with gel foam offers good value, backed by a 60-night trial and a 10-year guarantee.
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.
Save on an earlier or ex-display model
Some retailers still sell the earlier version of this mattress, or ex-display and returned stock at a lower price. These are the sizes where it costs less than the current model's best price.

FAQ's
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. Arthur Sleep offers free next day delivery.
