Layer Details
Pillow top
A soft, cloud-like pillow top sewn onto the surface, which means you get a plush, cushioned feel the moment you lie down. It softens the medium-firm tension underneath without undermining it.
Wool layers
Two layers of wool from Romney sheep, a breed native to Kent. Wool breathes and wicks moisture, which helps keep you at a steadier temperature through the night.
Pocket springs
Individually pocketed springs that respond to your shape and movements. Because each spring moves on its own, you get support where you press down and less disturbance when a partner shifts.
Nano springs
A layer of 1,000 smaller nano springs that contour more closely to your body. They fine-tune the support from the main springs, particularly around shoulders and hips.

Key benefits
- Leaves room for the rest of your furniture: The UK double leaves floor space for a wardrobe and drawers in rooms where the UK king, 15cm wider and 10cm longer, would start to crowd you.
- Calmer sharing at close quarters: Individually pocketed springs respond separately to each sleeper, which means you feel less of your partner shifting than 67.5cm each might suggest.
- Steadier temperature for two: Two layers of British wool from Romney sheep breathe and wick moisture, which helps when two people share a smaller surface and the bed warms up.
- Welcoming for visiting couples: A soft pillow top over medium-firm pocket springs gives guests an inviting first feel, and the support underneath stops them sinking through to the springs.
This size suits you if...
You share the bed with a partner and want a traditional sprung feel in a room of at least 2.6m x 2.8m, you're fitting out a guest room for visiting couples, or you sleep alone and like space for a cat or dog at your feet.
Consider another size if...
You and your partner are tall, broad-shouldered or restless sleepers who already feel cramped at night. We'd recommend the UK king instead, and we suggest at least 2.7m x 2.9m of room for it.

FAQ's
How much room does each person get on a Sleepeezee Thames UK double?
Two people sharing get 67.5cm each. That is the traditional couples' allowance, fine for pairs who sleep fairly close. If you want more, the UK king gives 75cm each, so the UK double gives 7.5cm less per person. The pocket springs help the narrower width feel calmer, because each spring responds to movement on its own.
Will a Sleepeezee Thames UK double fit in my bedroom with bedside tables on both sides?
We suggest a room of at least 2.6m x 2.8m for the UK double, with around 3m x 3m giving you comfortable space to walk round. If your room is close to that minimum, measure for bedside tables before you order. Slim tables on each side will leave more walking space than wide ones.
What size is the Sleepeezee Thames UK double in feet and inches?
The UK double measures 4ft 6in x 6ft 3in, which is 135 x 190cm. Check this against your bed frame or divan before buying. The Thames needs a base made for a UK double. A base for a UK small double will be 15cm too narrow.
Is the Sleepeezee Thames UK double long enough for tall couples?
The UK double is 190cm long, the same length as the UK single and UK small double. If either of you finds your feet reaching the end, the UK king is 10cm longer as well as 15cm wider. Allow for a bigger room, though: we suggest at least 2.7m x 2.9m for the UK king.
Is a Sleepeezee Thames UK double a good choice for a guest room?
For visiting couples it makes good sense. At 67.5cm each the UK double is comfortable for a few nights, and the pillow top gives guests a soft, welcoming first impression. Yes, a pillow top can't be flipped, but with only occasional use, rotating it every so often keeps wear even.
