Layer Details
Comfort fillings
Two layers combining polyester and cotton sit at the sleep surface, which means a soft, cushioned first impression when you lie down. The cotton adds a touch of natural breathability to the synthetic fill.
Soft white fibres
Beneath the comfort layers, two layers of soft white fibres help air circulate through the mattress. This works to move heat and moisture away from you, so the bed feels fresher for longer.
Pocket springs
1000 pocket springs form the core of the mattress, each moving independently to follow the shape of your body. Their curved design is intended to react quickly and spring back, so the mattress shouldn't feel dead or unresponsive when you change position.

Key benefits
- Fits a typical UK bedroom: We suggest a room of at least 2.6m x 2.8m, so the UK double suits many main bedrooms where a UK king would crowd out the wardrobe.
- Room for bedside tables: In a room of around 3m x 3m, the comfortable norm for a UK double, you can usually keep a table and lamp on both sides.
- Springs that follow each sleeper: The 1000 pocket springs move independently, which means the mattress shapes itself to each partner rather than flexing as one solid unit.
- Bedding you can find anywhere: Double sheets and a 200 x 200cm double duvet are widely stocked, which helps when you're kitting out a new home on a stretched budget.
- A proper bed for guests: Visiting couples get a genuine shared bed in a UK double, and a solo guest has plenty of space to spread out.
This size suits you if...
You share a bed in an ordinary UK bedroom and want a traditional sprung mattress that still leaves space for furniture around it, or you're setting up a spare room where visiting couples will stay a few nights at a time.
Consider another size if...
You and your partner both sprawl, or either of you finds 190cm too short. We'd recommend the UK king instead; allow at least 2.7m x 2.9m for it.

FAQ's
How much space does each person get on a Wentworth Mercer Natural Pocket 1000 double?
Two people sharing the UK double get 67.5cm each. The UK king gives 75cm each, so the UK double gives 7.5cm less per person. That's enough for most couples who sleep fairly still. If one of you tends to starfish, the extra width of the UK king may suit you better.
Will a UK double Natural Pocket 1000 fit in my bedroom with bedside tables?
We suggest a room of at least 2.6m x 2.8m for a UK double. For bedside tables on both sides with space to walk round, around 3m x 3m is more comfortable. Measure your room and your tables before ordering, and leave clearance for wardrobe doors and drawers to open.
Is the Natural Pocket 1000 UK double long enough for tall people?
The UK double is 190cm long, or 6ft 3in. That suits most adults, although taller sleepers may find their feet near the edge. The UK king is 10cm longer as well as 15cm wider, so it's the better choice if height is the issue.
What are the Wentworth Mercer Natural Pocket 1000 double dimensions in feet?
The UK double measures 135 x 190cm, which is 4ft 6in x 6ft 3in. Use those figures when checking a bed frame, because a frame labelled for a different standard, such as an EU double, may not match.
Is a Natural Pocket 1000 double a good choice for a guest room?
Yes, for most spare rooms. The UK double gives visiting couples a proper shared bed without filling a smaller room, and double bedding is easy to find. The mattress is listed as medium firm, so guests who like a very soft sink-in feel may find it a little firmer than their bed at home.
