HD foam comfort layers
Two HD foam layers sit on top and are described as breathable. That gives you a comfortable surface with less heat build-up.
1000 pocket spring system
Independent pocket springs that shape to the contours of your body. Each spring works on its own, so the mattress supports you where you need it.
Ecofoam base
A high-density foam foundation made from 100% recycled foam offcuts. It gives the springs a supportive base and uses recycled material.

Key benefits
- Space for bedside tables on both sides: We suggest a room of at least 2.6m x 2.8m for a UK double, so most UK main bedrooms can take this mattress with a small table on each side.
- Springs that respond to each sleeper: The 1000 independent pocket springs react where each of you presses in, so one partner's weight is less likely to pull the whole surface into a dip.
- A middle-ground feel for mixed couples: Komfi describes the feel as medium, which gives a back sleeper and a side sleeper sharing a UK double a reasonable chance of both being comfortable.
- Bedding you can buy anywhere: Standard double sheets and a 200 x 200cm double duvet suit the UK double, which keeps things simple when you're kitting out a first flat or a guest room on a careful budget.
- Floor space for the rest of the furniture: In a second bedroom or first flat, the UK double usually leaves enough floor for a wardrobe and a chest of drawers, where a UK king would start to crowd them.
This size suits you if...
You share the bed with a partner who doesn't spread out much, and the room also has to hold a wardrobe, drawers or a pair of bedside tables. It also suits a spare room where couples come to stay for a night or two.
Consider another size if...
One of you is a restless sleeper, or you both want more length. We'd recommend the UK king instead, which gives 75cm each; allow at least 2.7m x 2.9m for it.

FAQ's
Is the Komfi Vitality Hybrid Pocket 1000 UK double big enough for two people?
For most couples, yes. The UK double gives you 67.5cm each, which works well if you both sleep fairly still. It is 7.5cm less per person than the UK king. If either of you sleeps diagonally, or a cat tends to claim the foot of the bed, the extra room in the UK king may suit you better.
What size bedroom do I need for a Komfi Vitality Hybrid Pocket 1000 double?
We suggest at least 2.6m x 2.8m for a UK double, with around 3m x 3m feeling comfortable. At that size you can usually fit a bedside table on each side and still open a wardrobe door. Measure your room before you choose, especially in a newer flat where the bedrooms can be compact.
Komfi Vitality Hybrid Pocket 1000 UK double vs UK king: which should I choose?
The UK double is 15cm narrower and 10cm shorter than the UK king. Choose the UK double if your room is tight or you need space for other furniture. Choose the UK king if you're tall or want more personal space, and allow at least 2.7m x 2.9m for it. Both sizes have the same medium feel.
What are the Komfi Vitality Hybrid Pocket 1000 double dimensions in feet?
The UK double measures 4ft 6in x 6ft 3in, or 135 x 190cm. The mattress is 25cm deep, so check that your fitted sheets have deep enough pockets. If you're replacing an old double bed frame, these are the standard UK double measurements, so the mattress should fit an existing UK double base.
Is the UK double Komfi Vitality Hybrid a good choice for a guest room?
It suits a guest room well if you host couples, because the UK double is 15cm wider than the UK small double. If guests are usually on their own and the room is small, the UK small double needs less floor space. We suggest at least 2.4m x 2.8m for the UK small double, compared with 2.6m x 2.8m for the UK double.
