Layer Details
Knitted cover
A soft knitted finish that adds cosiness while allowing air to move through, which means the surface stays fresher overnight. It is designed for breathability rather than heat retention.
StayCool™ Gel
A 3cm gel layer with an open cell structure, which creates space for airflow and helps disperse excess body heat. This is the layer doing most of the work if you normally sleep warm.
Memory Foam
A 3cm layer that gently moulds to your shape, which means pressure eases at the shoulders and hips where you sink in most. Helpful if you wake with aches from firmer surfaces.
Pocket Springs
1800 individual pocket springs in total: 1000 SoftTech mini springs that contour closely to your body, plus 800 traditional pocket springs beneath for support. Because each spring moves independently, you should feel less disturbance from a partner turning over.

Key benefits
- Fits a typical bedroom: We suggest at least 2.6m x 2.8m, which means the UK double sits comfortably in most bedrooms, often with space for bedside tables on both sides.
- Calmer nights at close quarters: At 67.5cm each you lie nearer your partner, and the 1800 individual pocket springs move independently, so you should feel less of their turning over.
- Cooler for two: Two people in a UK double make more heat than one, so the 3cm StayCool gel layer, which helps disperse body warmth, matters a little more here.
- Easy bedding: Double sheets and a 200 x 200cm double duvet are sold almost everywhere, so dressing the bed never means hunting for an unusual size.
- Suits a guest room: If you host visiting couples, the UK double gives them a proper shared bed without the UK king's larger footprint crowding a modest spare room.
This size suits you if...
You share the bed with a partner and your bedroom is closer to 2.6m x 2.8m than the 3m x 3m comfortable norm, or you're kitting out a spare room for visiting couples and want a medium firm hybrid that helps sharers stay cooler.
Consider another size if...
One of you is tall or you both sprawl, since the UK double is 10cm shorter and gives 7.5cm less each than the UK king. We'd recommend the UK king if your room allows at least 2.7m x 2.9m.

FAQ's
Will my partner's movement disturb me on the Sleepeezee Jessica 1800 UK double?
Less than you might fear. At 67.5cm each you sleep closer together than on larger sizes, but the 1800 pocket springs each move on their own, so a partner rolling over is felt mainly where they lie. If one of you is a very restless sleeper, the extra width of the UK king may still suit you better.
Is the Sleepeezee Jessica 1800 UK double heavy to turn on your own?
Across verified owner reviews, the mattress is described as heavy, and a UK double at 135 x 190cm is an awkward shape for one person to handle. Sleepeezee doesn't publish a weight for this size, so if you rotate your mattress alone, plan to have a second pair of hands.
Sleepeezee Jessica 1800 UK double or UK small double for a small bedroom?
The UK double is 15cm wider than the UK small double, with the same length. We suggest at least 2.6m x 2.8m for the UK double and 2.4m x 2.8m for the UK small double. For two people sharing every night, the UK double is the better fit if your room allows it.
Will a UK double Sleepeezee Jessica 1800 fit a second bedroom with a wardrobe?
Often, yes. Allow at least 2.6m x 2.8m for the bed alone, with around 3m x 3m letting you add a wardrobe and drawers without squeezing past furniture. Measure where doors and wardrobe fronts open before deciding, because those swing zones use more floor than people expect.
What is the Sleepeezee Jessica 1800 double size in feet?
The double measures 4ft 6in x 6ft 3in, or 135 x 190cm. That is the standard UK double, so it fits any UK double bed frame or divan base without adjustment.
