Layer Details
Cotton comfort layer
Cotton fibres naturally wick away moisture, which means a drier, fresher feel through the night. This is the layer closest to you.
Polyester comfort layer
Polyester fibres encourage airflow to move heat and moisture away from your body. Helpful if you're a warm sleeper.
Soft white fibres
Two layers of soft white fibres provide cushioned comfort while helping the mattress retain its shape. They also add durability, so the surface should stay consistent for longer.
Pocket springs support system
A core of 2,000 sturdy steel springs, each encased in its own pocket, responds individually to motion and pressure. In practice, that means personalised support and less disturbance when a partner moves.

Key benefits
- Fits the bedrooms most people have: We suggest at least 2.6m x 2.8m, so in a typical master bedroom a UK double usually leaves space for a bedside table on each side.
- Less disturbance at close quarters: You sleep fairly close together at 67.5cm each, and the individually pocketed springs mean one person shifting is less likely to jolt the other awake.
- A sensible guest room bed: Visiting couples get a proper shared bed, and the firm feel suits back and front sleepers, although lightweight side sleepers may find it a little solid.
- Simple to dress: Double sheets and a 200 x 200cm double duvet are easy to find, so you won't need to hunt for bedding to fit a UK double.
- Easy to match to an older frame: At 4ft 6in x 6ft 3in, it lines up with frames listed in imperial, so measure your current bed base against those figures before ordering.
This size suits you if...
You share the bed every night in a typical UK bedroom and still want a bedside table on both sides, or you're furnishing a guest room or first flat where the bed has to sit alongside a wardrobe and a chest of drawers.
Consider another size if...
You and your partner are both tall or want more personal space. We'd recommend the UK king instead, which is 15cm wider and 10cm longer; allow at least 2.7m x 2.9m.

FAQ's
How much space does each person get on the Wentworth Mercer Natural Pocket 2000 UK double?
Each of you gets 67.5cm of width. That is 7.5cm less each than the UK king, so you'll be sleeping fairly close. The pocket springs help here, because each spring reacts on its own, which means your partner's movement is less likely to reach you.
What are the Wentworth Mercer Natural Pocket 2000 UK double dimensions in feet?
The UK double measures 135 x 190cm, which is 4ft 6in x 6ft 3in. If you're replacing a mattress on an existing frame or divan, check the frame's listed size against these figures before you buy.
Will a UK double Wentworth Mercer Natural Pocket 2000 fit a small bedroom?
We suggest at least 2.6m x 2.8m, with around 3m x 3m feeling comfortable once a wardrobe and drawers are in. If your room is under our minimum and you sleep alone, the UK single would suit you better; allow at least 2.1m x 2.8m for that size.
Is the UK double or UK king better for tall couples on this mattress?
The UK double is 190cm long, and the UK king is 10cm longer and 15cm wider. If either of you finds your feet near the end of the bed, sizing up to the UK king makes sense, provided your room meets our suggested 2.7m x 2.9m.
Is a double Wentworth Mercer Natural Pocket 2000 worth it for one person?
It can be. A solo sleeper gets the full 135cm width, with room left over for a dog or cat that claims a corner. The firm feel suits back and front sleepers best, although lightweight side sleepers may find it a little unforgiving at the shoulders.
