Layer Details
Cover
A knitted, breathable cover, which means air can move through the surface rather than getting trapped. It helps keep you at an even temperature through the night.
Natural Silk Layer
Silk is soft and lightweight, adding a gentle, comfortable feel at the surface. It's a filling more commonly found in premium mattresses.
Cashmere
A rare filling that's softer and finer than wool. Its presence is usually a sign of a quality build.
Authentic Traceable British Wool
Wool from British Cheviot sheep, 100% traceable from farm to shop. It adds a natural bounce and helps regulate temperature, which is good news for warm sleepers.
Support System
2,000 pocket springs, each sewn into its own fabric pocket so they move completely independently. That means better pressure relief and less disturbance from a partner shifting in the night.

Key benefits
- A shared bed that fits the room: At 135cm wide, the UK double leaves space for bedside tables on both sides in most bedrooms, where a UK king often would not.
- 67.5cm each for two people sharing: That's the width per sleeper in a UK double, and the 2,000 independent pocket springs mean a partner turning over disturbs you less within it.
- Natural fillings across the whole surface: Silk, cashmere and traceable British wool run the full 135 x 190cm, so both sleepers get the same breathable, temperature-steadying feel.
- The easiest size to dress: Double sheets and duvets are stocked everywhere, although at 34cm deep this mattress needs deep fitted sheets, so check the depth before buying.
- Simpler to get upstairs: A UK double is easier to turn on the stairs of an older terrace or a tight new build landing than the wider king sizes.
This size suits you if...
You're a couple who want the classic shared size in a room where a UK king would dominate, or you sleep alone and like space to spread out, perhaps with a dog or cat claiming a corner. It also suits a guest room that hosts visiting couples: at 4ft 6in x 6ft 3in, it sleeps two comfortably without demanding a large room.
Consider another size if...
Your room is smaller than the 2.6m x 2.8m we suggest as a minimum, or you're a couple who find 67.5cm each a little tight. For the first, the UK small double would suit you better; for the second, we'd recommend the UK king instead.

FAQ's
Is the Highgrove Somerset 2000 in a UK double big enough for a couple?
Yes, for most couples. A UK double gives 67.5cm each for two people sharing, and the 2,000 pocket springs move independently, so you feel less of a partner's movement. If either of you is tall or a restless sleeper, the UK king adds 15cm of width and 10cm of length.
What room size do I need for the Somerset 2000 UK double?
Allow at least 2.6m x 2.8m, which is our own suggested minimum rather than Highgrove's. That leaves walking space around the 135 x 190cm mattress and, in most rooms, space for bedside tables on both sides. Around 3m x 3m feels comfortable rather than tight.
Will the UK double Somerset 2000 fit up a narrow staircase?
It's the easiest couples' size to manoeuvre: at 135cm wide it turns a terrace staircase or a tight new build landing more readily than a UK king or UK super king would. It is a substantial mattress though, at 34cm deep, so two people carrying it is sensible.
What bedding fits this mattress in a double?
Standard double sheets and a double duvet fit the 135 x 190cm footprint, and both are widely stocked at every price. The one catch is depth: at 34cm this is a tall mattress, so choose deep or extra-deep fitted sheets rather than standard ones.
How does the double compare with the small double for this mattress?
The UK double is 15cm wider than the UK small double, and the two are the same length. For a couple, that extra width is usually worth having. The UK small double earns consideration where the room is genuinely small, such as a first flat or a compact second bedroom.
