Layer Details
Tufted knitted cover
A traditionally tufted knitted cover holds the comfort layers in place through all base positions. That means the fillings should stay put as the bed moves up and down.
1000 pocket spring unit
1000 pocket springs respond independently to body weight. This promotes natural spinal alignment and reduces motion transfer, so you should be less disturbed by a partner's movement.
Natural wool and fibre fillings
British wool sits closest to the cover and acts as a natural insulator, with deep fibre and polyester fillings below it. You get a natural, medium-soft comfort layer, though the wool's insulating effect may feel warm if you sleep hot.

Key benefits
- Room for two on one base: You each get 67.5cm of width, which means two adults can share an adjustable frame comfortably, although broad-shouldered couples may feel a little close.
- Fits a typical bedroom: We suggest allowing at least 2.6m x 2.8m, which means most UK main bedrooms can take the bed and still leave space to walk around it.
- Space for bedside tables: At around 3m x 3m you can usually fit a bedside table on each side, so both of you keep a lamp and a phone within reach while sitting upright.
- A step up from the small double: The UK double is 15cm wider than the UK small double at the same length, which means a noticeably roomier shared bed on a base that still fits most rooms.
- Easy bedding to find: Standard double sheets and a 200 x 200cm double duvet fit this size, so you won't be hunting for specialist bedding to go with a new adjustable setup.
This size suits you if...
You share the bed with a partner and want an adjustable base you can both use, your bedroom is at least 2.6m x 2.8m, or you sleep alone but like room for a dog or cat curled up at the foot while you read propped up.
Consider another size if...
Your room is under 2.6m x 2.8m, or you'll sleep alone in a smaller space. We'd recommend the UK small double instead, allowing at least 2.4m x 2.8m.

FAQ's
Is the UK double the biggest size of the Sleepeezee In-Motion Natural Pocket 1000?
Yes. The range runs from UK small single up to UK double, so the UK double is as large as this adjustable mattress goes. If you and your partner want a UK king, which gives 75cm each, you'll need to look at a different adjustable mattress, because this model isn't made in that size.
How much space does each person get on a UK double adjustable mattress?
The UK double gives 67.5cm each for two people sharing. That suits most couples, although if either of you sprawls you may find it a little snug. A UK king would give 7.5cm more each, but Sleepeezee doesn't offer this model in a UK king.
What size bedroom do I need for a UK double adjustable bed?
We suggest at least 2.6m x 2.8m for a UK double, with around 3m x 3m giving comfortable space for bedside tables on both sides. In a tighter second bedroom, the UK small double needs a little less, and we suggest at least 2.4m x 2.8m for that size.
Will a UK double mattress fit my adjustable bed base?
This mattress measures 135 x 190cm, so it should only go on an adjustable base built for a UK double. Measure your base or check the manufacturer's listing before ordering, because a mattress that overhangs or falls short of a moving frame can shift about as the base changes position.
Is a UK double or UK small double better for a couple on an adjustable bed?
For two adults sleeping together every night, the UK double is the better choice. It is 15cm wider than the UK small double at the same length, which gives you both more room to settle once the base is raised. The UK small double suits couples mainly when floor space is the limiting factor.
