Layer Details
Top layer
A premium comfort layer sits on top, although the listing doesn't specify exactly what it's made from. It provides the initial cushioning you'll feel when you lie down.
Core
A 1000 pocket spring system forms the core, which means each spring responds to your body individually rather than as one unit. You get support where you press down and less motion transfer across the bed.
Border
A 10cm foam encapsulated border wraps the springs, giving edge-to-edge support and a reinforced sleep surface. In practice, the mattress feels usable across its full width, including when sitting on the side.

- A shared size that fits real bedrooms: At 135 x 190cm, this footprint leaves space for wardrobes and drawers in an ordinary UK bedroom, where a UK king often would not.
- Full use of the width: The 10cm foam encapsulated border keeps the surface supportive to the sides, which matters when two people are sharing 67.5cm each.
- Less disturbance across the bed: The 1000 pocket springs move independently, so on a shared double you feel less of a partner turning over beside you.
- Room for bedside tables on both sides: We suggest allowing at least 2.6m x 2.8m, which in most rooms still leaves space for a table each side of the bed.
- Easy to dress cheaply: Standard double sheets and a 200 x 200cm double duvet are sold everywhere, so you won't hunt for bedding at odd sizes or prices.
This size suits you if...
You share the bed with a partner and want the traditional couples' size in a room that can't comfortably take anything bigger, or you sleep alone and want space to stretch out, perhaps with a dog or cat claiming a corner. It also makes sense for a guest room that hosts visiting couples, since the medium firm feel suits most back and combination sleepers.
Consider another size if...
You and your partner both like to spread out, or one of you is over 6ft 3in and needs the extra length. We'd recommend the UK king instead: it's 15cm wider and 10cm longer, and we suggest at least 2.7m x 2.9m of room for it.

Is the Hotel Arthur UK double big enough for two adults?
It works for most couples, though at 67.5cm each for two people sharing, it's a snug rather than roomy fit. The foam encapsulated border helps, because the surface stays supportive right to the edges rather than sagging where an elbow or shoulder ends up. If either of you sprawls, the UK king gives you 15cm more width.
What size room do I need for the Hotel Arthur in a UK double?
We suggest allowing at least 2.6m x 2.8m, with around 3m x 3m the comfortable norm. That's our own guidance, not Arthur Sleep's. In a room near the minimum, you'll still manage bedside tables on both sides, which is one of the main reasons couples pick a UK double over sizing up.
Should I get the Hotel Arthur in a UK double or a UK king?
The UK double is 15cm narrower and 10cm shorter than the UK king. If your room meets our suggested 2.7m x 2.9m for the UK king and you both value space, size up. If floor space is tight, or the bed shares the room with a wardrobe and drawers, the UK double is the sensible pick.
Will a Hotel Arthur double fit up narrow stairs?
At 135cm wide it's more manageable on a turning staircase or a tight new build landing than the larger sizes, but a pocket spring mattress with a foam encapsulated border doesn't fold or roll like an all-foam one. Measure the tightest turn on the route before ordering, and check the retailer's delivery access guidance.
Is the UK double Hotel Arthur good for a guest room?
Yes, it's a sensible guest room choice: the size accommodates visiting couples as well as solo guests, and the medium firm feel suits most back and combination sleepers rather than dividing opinion. The pocket springs also limit motion transfer, so two guests unused to sharing a bed will disturb each other less.
