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.

- A sensible width for two: At 67.5cm each for two people sharing, a couple gets a workable amount of space without the bed dominating a typical UK bedroom.
- Springs that suit sharing: The 800 pocket springs move independently, which means a partner turning over at 3am is less likely to wake you.
- Fits rooms a king would crowd: We suggest at least 2.6m x 2.8m, which leaves most bedrooms with space for bedside tables on both sides.
- Kind to a stretched budget: If you're kitting out a first flat or a whole house at once, a budget-priced hybrid in the standard couples' size keeps costs down without settling for open coils.
- Easy to dress: Standard double sheets and a 200 x 200cm duvet are sold everywhere, so bedding costs stay low too.
- Gel comfort across the shared surface: The gel foam layer works to draw heat away, useful when two bodies warm the bed more than one.
This size suits you if...
You share the bed with a partner and your room suits the classic double footprint, you're furnishing a first flat or guest room on a careful budget, or you sleep alone and want room to spread out, perhaps with a dog or cat claiming a corner. It fits average-weight back and side sleepers happiest on a medium feel.
Consider another size if...
You and your partner both like space, or one of you is tall, since the UK double runs 190cm long. We'd recommend the UK king instead: it's 15cm wider and 10cm longer, and needs a room of at least 2.7m x 2.9m.

Is the Gel Arthur double big enough for two adults?
For most couples, yes. You each get 67.5cm of width, and the 800 pocket springs respond to each of you separately, so one person shifting about disturbs the other less than on an open-coil bed. Two heavier adults sharing may find the support a little light over time, and the UK king offers noticeably more room.
What room size do I need for the Gel Arthur in a UK double?
We suggest at least 2.6m x 2.8m, with around 3m x 3m the comfortable norm. That allows walking space on both sides and room for bedside tables, a wardrobe and a chest of drawers, which is the usual squeeze in a second bedroom or first flat. Measure with the door swing in mind.
Should I get the Gel Arthur in a double or a king?
The UK double suits most shared bedrooms and costs less to dress. The UK king is 15cm wider and 10cm longer, worth it if either of you is tall or you both like space, but it needs at least 2.7m x 2.9m of floor. If your room is on the smaller side, the UK double is the safer call.
Will a double mattress fit up the stairs in an older house?
Usually, yes. At 135 x 190cm the UK double is easier to manoeuvre round the turning stairs of older terraces and tight new build landings than a UK king would be, and the hybrid construction has some flex to it. Measure your narrowest turn before ordering, particularly if the staircase has a low ceiling or tight winder.
Is the Gel Arthur double a good choice for a guest room?
It's a reasonable fit. The UK double is the standard size visiting couples expect, the medium feel suits a wide range of sleepers, and the modest price makes sense for a bed used a few weeks a year. Its 4ft 6in x 6ft 3in footprint also leaves room for guests' luggage in a smaller spare room.
