Key benefits
- Every centimetre of a narrow bed is usable: Edge-to-edge encapsulated springs firm up the perimeter, which means a child can sit on the side to pull on socks, or you can sleep near the edge, without feeling it dip.
- Leaves room for the rest of the bedroom: We suggest allowing at least 2.1m x 2.8m, so a desk, wardrobe or toy storage can share the floor rather than the bed taking over.
- Fits under a sloping loft ceiling: In a loft conversion where only a slim strip of floor has full head height, a 90cm wide mattress can sit along the low wall without blocking the usable middle of the room.
- Supportive for a growing body: Its 1,200 pocket springs each respond on their own, which means a teenager going through growth spurts gets support where they press down rather than a hammock effect.
- A sensible pair for a twin guest room: Two UK singles let friends or siblings who would rather not share a bed each have their own mattress with the same medium firm feel.
This size suits you if...
You sleep alone, or you're buying for a child or teenager whose room also has to fit a desk and wardrobe. It also suits a spare room that works as a home office most of the week and only needs to sleep a guest now and then.
Consider another size if...
You share the bed with a partner, or you're an adult who likes space to sprawl. We'd recommend the UK small double instead, which is 30cm wider and needs at least 2.4m x 2.8m.

FAQ's
Will the Sleepeezee Tranquil 1200 UK single fit a bunk bed or mid sleeper?
The UK single is the right footprint for most bunk, cabin and mid sleeper frames. Raised frames usually set a maximum mattress depth for the safety rail, though, and Sleepeezee doesn't publish a depth for this mattress. Check the frame maker's limit and ask the retailer for the depth before you order.
Is the Tranquil 1200 in a UK single too firm for a child?
It may feel a little firm for a very light child who sleeps on their side, as there's less body weight to press into the springs at the shoulders and hips. For most older children and teenagers, the medium firm feel gives steady support that holds up as they grow.
What room size do I need for a Sleepeezee Tranquil 1200 UK single?
We suggest at least 2.1m x 2.8m of floor space for a UK single. That leaves room to get in and out comfortably and still fit other furniture. If you're weighing up two singles side by side, measure for both beds plus a walkway between them.
Should a teenager have the Tranquil 1200 in a UK single or a UK small double?
A UK single is fine for most teenagers and keeps the floor free for a desk. If they are tall, broad or restless, the UK small double is 30cm wider at the same length, and we suggest at least 2.4m x 2.8m for it.
Is a UK single Tranquil 1200 good for a spare room office?
Yes, if the room is mostly a workspace. A UK single leaves space for a desk and chair, and the firm edges mean it can double as seating during the day. Guests arriving as a couple would be better served by a larger size.
