Layer Details
Bamboo cover
An ultra-soft knitted bamboo cover wicks away moisture, which means less clamminess on warm nights. It also has a naturally antibacterial finish to help prevent odours forming.
Pillow top
A cloud-like pillow top adds a plush, indulgent surface feel over the firm core. It includes a layer of cooling gel for soothing relief as you sleep.
Staycool gel
Dual layers of Staycool gel regulate your temperature through the night. They also give pressure-sensitive support, adapting to where your body pushes in most.
Pocket springs
2,400 pocket springs in the king size move independently to cushion your body, which means less disturbance when a partner shifts. Highly adaptive nano pocket springs add a finer layer of support.
Side support border
An enhanced side support border creates a durable edge around the mattress. This helps prevent dipping or sagging where you sit or sleep near the side.

Key benefits
- Space left for bedside tables: At 135 x 190cm, the UK double often leaves room for a bedside table on each side in bedrooms where a UK king would squeeze one out.
- An edge you will actually use: With 67.5cm each for two sharing, you are likely to sleep nearer the side, so the reinforced side support border helps the outer edge resist dipping.
- Less disturbance at close quarters: The pocket springs move independently, which means you feel less of your partner turning over, and that matters more when you share a narrower bed.
- Help with the heat of two: Two people in a UK double give off more warmth than one, and the bamboo cover and Staycool gel layers are there to help keep that in check.
- Simple to dress: Double sheets and a 200 x 200cm double duvet are sold almost everywhere, so finding bedding for this size is straightforward.
This size suits you if...
You share with a partner in a bedroom of at least 2.6m x 2.8m and still want bedside tables on both sides, or you are furnishing a second bedroom or first flat where the bed has to leave space for a wardrobe and drawers.
Consider another size if...
You and your partner both like to spread out, or one of you is a restless sleeper. We'd recommend the UK king instead, which gives 75cm each; allow at least 2.7m x 2.9m.

FAQ's
Will a Sleepeezee Witham UK double fit in a small bedroom?
We suggest allowing at least 2.6m x 2.8m for a UK double, with around 3m x 3m the comfortable norm. Below that, getting in and out of bed and opening wardrobe doors starts to feel cramped. If your room is close to the minimum, measure where bedside tables would go before you buy.
How much space does each person get on a Sleepeezee Witham double?
Two people sharing the UK double get 67.5cm each. That is enough for many couples, but it means you will spend more time near the sides, which is where the Witham's reinforced side support border helps keep the edge from sagging.
Sleepeezee Witham UK double vs UK king: how much room do you lose?
The UK double is 15cm narrower and 10cm shorter than the UK king, and gives 7.5cm less each for two sharing. The trade is floor space: we suggest at least 2.7m x 2.9m for the UK king, against 2.6m x 2.8m for the UK double.
Is the Sleepeezee Witham UK double a good choice for a guest room?
It works well where visiting couples stay, as a UK double fits most spare rooms and double bedding is easy to keep on hand. The Witham is firm tension, though, so guests who prefer a softer bed may find it a little solid, even with the pillow top.
What are the Sleepeezee Witham double mattress dimensions in feet?
The UK double measures 4ft 6in x 6ft 3in, which is 135 x 190cm. Useful if you are matching it to an older bed frame described in imperial sizes, as many inherited or second-hand frames are.
