Layer Details
Cotton and Polyester Comfort Layer
Two layers blending cotton and polyester give a cushioned surface feel. The cotton naturally wicks away moisture while the polyester improves airflow, which means less heat building up as you sleep.
Soft White Fibres
Two layers of soft white fibres sit beneath the top layer. These are resilient and cushioning, which helps the comfortable feel last longer.
Pocket Spring Core
A core of 2000 durable steel pocket springs, each encased in its own cloth pocket. Because the springs move independently, support adjusts to each part of your body rather than the mattress compressing as one block.

Key benefits
- A shared size that suits typical rooms: At 135 x 190cm, or 4ft 6in x 6ft 3in, the UK double leaves space for a wardrobe and drawers in rooms where a king would dominate.
- Independent springs for two sleepers: The 2000 pocket springs each move on their own, which means one partner turning over should disturb the other less than an open coil bed would.
- Firm support across a shared surface: An extra firm rating suits couples who both prefer to sleep on top of a mattress, although lighter side sleepers may feel it at the hips and shoulders.
- Cooler for two bodies close together: Two people at 67.5cm each generate more shared warmth, and the cotton comfort layers help by wicking moisture away from the surface.
- One flaw to weigh up: Across verified owner reviews, some people describe the feel as nearer medium firm, so a couple wanting firmness guaranteed should keep that in mind.
This size suits you if...
You share the bed every night with a partner who also likes a firm surface, your bedroom measures at least 2.6m x 2.8m, or you're furnishing a spare room where visiting couples will sleep for a few nights at a time.
Consider another size if...
You both sleep restlessly or already find 67.5cm each a squeeze. We'd recommend the UK king instead, which gives 75cm each and needs a room of at least 2.7m x 2.9m.

FAQ's
How much room does each person get on a Wentworth Mercer Natural Pocket 2000 Ortho UK double?
Two people sharing get 67.5cm each. That suits most couples who sleep fairly still, and the independent pocket springs help keep one partner's movement from reaching the other. If either of you sprawls, the UK king gives 75cm each, which is 7.5cm more per person.
Will a UK double Natural Pocket 2000 fit with bedside tables on both sides?
We suggest a room of at least 2.6m x 2.8m for a UK double, with around 3m x 3m the comfortable norm. At the smaller end, slim bedside tables on both sides usually still work, but check your door swing and wardrobe clearance before you order.
Natural Pocket 2000 Ortho double vs king: how much bigger is the king?
The UK king is 15cm wider and 10cm longer than the UK double. In a shared bed that works out at 7.5cm more each. We suggest at least 2.7m x 2.9m for the UK king, so measure carefully if your room is close to the UK double minimum.
Is the extra firm Natural Pocket 2000 double good for couples with different weights?
Because each of the 2000 springs responds on its own, a heavier and a lighter partner are supported separately rather than rolling towards the middle. On 67.5cm each, a lighter side sleeper may notice the firmness more than their partner does, and some owners report the feel is softer than billed.
Is a Wentworth Mercer UK double a good choice for a guest room?
For a spare room that hosts couples, the UK double makes sense: it sleeps two while leaving floor space for a chest of drawers or a desk. Bear in mind the extra firm feel may not suit every guest. Double sheets and a 200 x 200cm double duvet are easy to find.
