Layer Details
- Comfort fillings. Natural wool and cotton fillings sit at the top, finely layered for a cosy surface feel. Beneath them, 7000 mini pocket springs add a sumptuous, cushioned quality without softening the underlying support.
- Support system. The core is 1000 traditional pocket springs, each encased in its own fabric pocket. Every spring reacts independently to your body shape, which means support where you need it and less disturbance from a partner's movement.
- Edge support. Butterfly springs around the border create a sturdy edge, backed by a rod frame that secures the spring system right to the perimeter. In practice, this means you can use the full width of the bed and sitting on the edge feels stable.

- Room left for bedside tables: At 135cm wide, the UK double usually leaves space in an ordinary bedroom for a bedside table on each side, something a UK king can crowd out.
- Usable right to the edge: Butterfly springs and a rod frame firm up the border, which means the 67.5cm each of you gets stays usable to the side rather than sloping away.
- Less disturbance when sharing: The 1000 pocket springs react independently, so when one of you shifts in the night the other feels less of it, which helps on a width where couples sleep fairly close.
- Cooler for two: Wool, cotton and silk fillings breathe well, a real help on a shared UK double, where warmth from two bodies tends to build up in the middle.
- Simple to dress: Double fitted sheets and a 200 x 200cm double duvet are sold almost everywhere, so kitting out the bed takes no hunting around.
This size suits you if...
You share the bed every night and your room is close to our suggested 2.6m x 2.8m minimum, so a larger size would crowd out wardrobes or bedside tables, or you're furnishing a guest room where visiting couples need a proper shared bed with firm, breathable support.
Consider another size if...
You're both broad-shouldered or restless sleepers and 67.5cm each already feels tight. We'd recommend the UK king instead, which gives 75cm each; allow at least 2.7m x 2.9m for it.

Will the Premium Naturals 8000 UK double fit in a small bedroom?
We suggest at least 2.6m x 2.8m for a UK double, with around 3m x 3m the comfortable norm once a wardrobe and drawers are in. If your second bedroom or first flat is tighter than that, the UK small double would suit you better, and we suggest at least 2.4m x 2.8m for it.
How much space does each person get on a Wentworth Mercer Premium Naturals 8000 double?
Two people sharing the UK double get 67.5cm each. The sturdy spring border means that width is usable almost to the edge. If you want more elbow room, the UK king gives 75cm each, 7.5cm more per person, though it needs a room of at least 2.7m x 2.9m.
Is the Premium Naturals 8000 UK double long enough for tall people?
The UK double measures 190cm long, or 6ft 3in. That suits most adults, but if either of you is tall enough for your feet to reach the end, the UK king is 10cm longer as well as 15cm wider. Allow at least 2.7m x 2.9m for the UK king.
Is a UK double Premium Naturals 8000 a good choice for a guest room?
For a guest room that hosts visiting couples, the UK double gives two people their own 67.5cm each without dominating a smaller spare room. The firm, supportive feel suits most guests, although lightweight side sleepers who prefer something softer may find it a little firm for a short stay.
Is a UK double Premium Naturals 8000 too big for one person?
Not if you like to spread out. A UK double is 45cm wider than a UK single, which leaves a solo sleeper plenty of room even with a dog or cat claiming a corner. If you sleep alone in a compact room, the UK small double is 15cm narrower and needs at least 2.4m x 2.8m.
