Layer Details
- Cool-touch knitted cover. A knitted cover with a cool-touch finish, which means the surface feels cooler when you first lie down. Helpful if you're a warm sleeper.
- Pillow top: soft comfort layer. A soft layer at the top of the pillow top that provides the initial cushioning you feel when you get into bed.
- Pillow top: high-density support layer. A denser layer beneath the soft one, which means the cushioning doesn't collapse under your weight. It keeps the pillow top feeling supportive rather than saggy.
- Pillow top: memory foam. Memory foam moulds to your shape, easing pressure at the shoulders and hips. This is part of what softens the firm feel at the surface.
- Pillow top: Dreamzone profiled body-contouring gel foam. A profiled gel foam that contours to your body, which means support follows your shape rather than pushing back uniformly. The gel element also helps with heat.
- Pillow top: mini springs. Small springs within the pillow top add responsiveness, so the surface springs back quickly when you move. This makes changing position easier than on all-foam tops.
- Core: traditional pocket springs. Individually wrapped springs that move independently, which means less motion transfer to your partner and support tailored to where your body needs it.
- Core: mini springs. A second layer of mini springs in the core adds a finer level of responsiveness beneath the main pocket springs.
- Core: high-density support layer. A firm base layer that anchors the whole mattress, giving the springs a stable foundation and helping edge-to-edge durability.

- Fits a typical shared bedroom: We suggest allowing at least 2.6m x 2.8m, which means most standard master and second bedrooms can hold the UK double with space left to move around it.
- Quieter nights for couples: Individually wrapped pocket springs move on their own, which means a restless partner is less noticeable on a width where you sleep fairly close together.
- Firm support without a hard surface: The gel and memory foam pillow top cushions shoulders and hips, so two sleepers sharing a firm mattress are less likely to feel it as solid.
- Easier to change position: Mini springs in the pillow top respond quickly, which helps when you're shifting position in a shared bed without much spare width either side.
- Cooler for warm couples: Two bodies generate more heat, and the cool-touch knitted cover feels fresher when you first lie down, a slight help if either of you runs warm.
- Simple to dress: The UK double measures 4ft 6in x 6ft 3in, a standard size that double sheets and a 200 x 200cm double duvet are made to fit.
This size suits you if...
You share the bed every night and your bedroom needs to keep bedside tables on both sides, or you're setting up a first flat where the wardrobe and drawers still need their share of the floor. It also suits a guest room where visiting couples want proper firm support for a few nights.
Consider another size if...
One of you is tall or you both like to spread out, and your room has space to spare. We'd recommend the UK king instead: it's 15cm wider and 10cm longer, so allow at least 2.7m x 2.9m.

How much space does each person get on a Sleepeezee SensaGel 4000 UK double?
Two people sharing the UK double get 67.5cm of width each. That's comfortable for most couples who sleep fairly still, and the pocket spring core helps by limiting how much movement travels across the mattress. If either of you sleeps diagonally or starfishes, you may find it a little snug.
What room size do I need for a Sleepeezee SensaGel 4000 UK double?
We suggest at least 2.6m x 2.8m for the UK double, with around 3m x 3m giving a more comfortable amount of space. At 30cm deep, the SensaGel 4000 sits tall on a frame, so a smaller room may feel slightly more filled than the floor measurements alone suggest.
How much extra room would the SensaGel 4000 UK king give a couple over the UK double?
The UK king is 15cm wider and 10cm longer than the UK double, giving 75cm each for two sharing, so the UK double gives 7.5cm less per person. The trade-off is the room: we suggest at least 2.7m x 2.9m for the UK king.
Is the Sleepeezee SensaGel 4000 UK double long enough for a tall sleeper?
The UK double is 190cm long, the same length as the UK single and UK small double. If you or your partner are tall and your feet already reach the end of a bed, the UK king adds 10cm of length, which may suit you better.
Should I choose the SensaGel 4000 in a UK small double or a UK double for a small bedroom?
The UK double is 15cm wider than the UK small double, with the same length. For a couple, that extra width makes a real difference to sharing. The UK small double suits tighter rooms, where we suggest at least 2.4m x 2.8m, and works better for one sleeper than two.
