Layer Details
Cool-touch knitted cover
A knitted cover with a cool-touch finish, which means the surface feels pleasantly cool when you first lie down.
Pillow top
A topper filled with Dreamzone gel foam and memory foam for that plush, sink-in feel. It's removable, so you can turn and rotate it to help maintain its shape over time.
Dreamzone profiled body-contouring gel foam
This gel foam responds to your heat and pressure, moulding to your shape to relieve pressure points. It also helps draw heat away from your body, useful if softer mattresses usually leave you warm.
Soft comfort layer
An additional soft layer that adds to the gentle, cushioned feel before you reach the springs.
Mini springs and pocket springs
Mini springs sit alongside traditional pocket springs, each adjusting independently to your body. In practice this means support that follows your shape rather than a uniform push-back.
High-density support layer
A firm foundation at the base that keeps everything above it stable and supported.

Key benefits
- A generous feel for one: The pillow top and gel foam give a solo sleeper the same plush, cradling surface as the larger sizes, which means a small room doesn't mean a pared-back bed.
- Leaves space in a busy bedroom: At 90cm wide, the UK single leaves room for a desk, wardrobe and storage alongside it, which matters in a child's or teenager's room where the bed competes for floor space.
- Two singles for a flexible guest room: A pair of UK singles lets a spare room host two friends or siblings separately, and you can push them together if a couple stays instead.
- Cooler for warm sleepers in snug rooms: The gel foam is designed to draw heat away from your body, which helps in a small bedroom or loft conversion where warmth tends to build up overnight.
- Easy to turn on your own: The removable pillow top can be turned and rotated to help it keep its shape, and a UK single is a manageable size for one person to handle.
This size suits you if...
You sleep alone and like a soft, sink-in surface, especially if you sleep on your side. It also suits you if you're furnishing a teenager's room or a spare room where floor space is tight, or you want two separate beds for guests rather than one shared double.
Consider another size if...
You share the bed with a partner, because a UK single is designed for one. We'd recommend the UK double instead, which gives 67.5cm each for two sharing; allow at least 2.6m x 2.8m.

FAQ's
Will the Sleepeezee SensaGel 12000 UK single fit a bunk bed or mid sleeper?
Possibly not. At 40cm, this is a deep mattress, and raised frames such as bunks, cabin beds and mid sleepers often set a maximum mattress depth so the guard rail stays effective. Check your frame maker's guidance before buying. For a floor-standing single bed, the depth simply means a higher, more substantial sleeping surface.
What size room do I need for a UK single SensaGel 12000?
We suggest allowing at least 2.1m x 2.8m of floor space for a UK single. That leaves room to walk around the bed and open drawers or a wardrobe. In a loft conversion, bear in mind that a 40cm mattress lifts you closer to a sloping ceiling, so check you can sit up comfortably.
Sleepeezee SensaGel 12000 single vs small double: which should I choose?
The UK single is 30cm narrower than the UK small double, and both are the same length. If you sleep alone but spread out, or a pet joins you, the UK small double gives you more room. We suggest at least 2.4m x 2.8m for the UK small double.
Is the UK single long enough for a tall teenager?
The UK single is 190cm long, the same length as the UK small double and UK double. If your teenager is very tall and their feet already reach the end, the UK king is 10cm longer, although it is a far bigger bed and needs at least 2.7m x 2.9m of floor space.
Is the SensaGel 12000 in a UK single a good choice for a guest room?
It can be, especially if you fit two UK singles side by side so friends, siblings or a couple can all be accommodated. Bear in mind the soft feel won't suit guests who prefer a firmer bed, so it's best if the people staying with you tend to sleep on their side.
