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
- Room for two proper sleep styles: At 75cm each for two people sharing, you can both spread out, which means fewer accidental elbows when one of you shifts position.
- Quiet exits on different schedules: Each of the 2,000 springs moves independently, so a 5am alarm on one side transfers very little movement across a bed this wide.
- Length for taller sleepers: At 200cm long, or 5ft x 6ft 6in in old money, anyone approaching six foot gets their feet on the mattress rather than off the end.
- Natural fillings that breathe across a bigger surface: Wool and silk help regulate temperature, useful when two bodies are warming one mattress all night.
- Fits without swallowing the room: We suggest a room of at least 2.7m x 2.9m, which most UK master bedrooms can manage where a UK super king would struggle.
This size suits you if...
You share the bed every night and a UK double has started to feel cramped, especially if one of you gets up hours before the other. It's also the size to pick if either partner is tall, since the 200cm length is a genuine difference you feel. And if the dog treats the bed as its own, the extra width absorbs that better than a smaller size would.
Consider another size if...
You sleep alone, or your bedroom falls short of our suggested 2.7m x 2.9m minimum. In either case the UK double of the same mattress would suit you better and leave more floor space around the bed.

FAQ's
Is the UK king version of the Somerset 2000 good for couples on different schedules?
Yes, and it's arguably where this mattress makes most sense. The 2,000 pocket springs each move independently, so movement on one side doesn't travel far, and at 150cm wide there's real distance between you. One of you can slip out at dawn while the other, a little enviably, sleeps on.
Is a UK king long enough if I'm over six foot?
It helps considerably. The UK king runs to 200cm long, which suits most people approaching or just over six foot. If you're taller still, the UK super king shares the same 200cm length, so sizing up buys width rather than length; the UK king is usually the sensible choice for a tall sleeper.
What fitted sheets do I need for the Highgrove Somerset 2000 in a UK king?
You'll need UK king sheets for the 150 x 200cm surface, but check the depth before you buy. This mattress is 34cm deep, which standard fitted sheets often won't stretch over, so look for deep or extra-deep king sheets. A 230 x 220cm king duvet is the usual pairing.
How much bigger is the UK king than the double for this mattress?
The UK king is 15cm wider than the UK double, and it adds length too, at 200cm against the double's 190cm. On a mattress with independent pocket springs, that extra width does more than it sounds: it puts more undisturbed springs between you and your partner, which is most of the point of upgrading.
Where can I buy the Somerset 2000 in a UK king?
Compare the retailers listed on this page; the prices shown are updated as retailers change them, so it's worth checking back rather than assuming today's price holds. Availability in a UK king can differ from the other sizes, so the live table here is the reliable place to look.
