- Room to sprawl on your own: At 30cm wider than the UK single, you can sleep diagonally or starfish without a hand dropping off the side.
- Firm right to the sides: The springs reach the perimeter, which means lying close to the edge of a 120cm mattress feels steady rather than sloping.
- Fits tighter bedrooms: Being 15cm narrower than the UK double can leave enough floor for a wardrobe door to swing open, or a desk to sit beside the bed.
- A step up for a growing teenager: If your teenager has outgrown a single but the bedroom has no spare floor to give, the UK small double adds width without taking over the room.
- Workable for occasional guests: Two people can share for a weekend, and the independent springs mean one guest turning over disturbs the other a little less.
- Standard 4ft sizing: Measuring 4ft x 6ft 3in, it fits common UK small double frames, so you are unlikely to need anything made to order.
This size suits you if...
You sleep alone and feel cramped on a single, or you're furnishing a compact bedroom, a loft conversion or a guest room where a couple stays now and then, and you want a medium firm feel that stays supportive right to the sides.
Consider another size if...
You share the bed with a partner every night. We'd recommend the UK double instead, which gives 67.5cm each for two sharing; allow at least 2.6m x 2.8m for the UK double.

Is the Sleepeezee Tranquil 1200 small double big enough for one adult?
For most solo adults, yes. The UK small double is 120 x 190cm, which gives you 30cm more width than the UK single. The length is the same as the UK single, so if you're very tall and your feet already reach the end of a single, you'll notice that here too.
What room size do I need for a Tranquil 1200 in a UK small double?
We suggest at least 2.4m x 2.8m for the UK small double. That leaves space to walk round the bed and open drawers. In a loft conversion with sloping ceilings, measure the floor where you can actually stand, because headroom beside the bed matters more than total floor area.
Can two people share the Sleepeezee Tranquil 1200 small double?
For the odd night, yes. Guests staying over will find it close quarters, but the edge-to-edge springs mean neither person is left perching on a soft rim. For a couple sharing every night, the UK double is more comfortable because it gives 67.5cm each.
Should I get the Tranquil 1200 in a small double or a double for a teenager?
If the bedroom is small, the UK small double is often the better fit. It is 15cm narrower than the UK double but the same length, so your teenager keeps the full leg room. The UK double needs at least 2.6m x 2.8m of room, compared with 2.4m x 2.8m for the UK small double.
What bed frame fits a Sleepeezee Tranquil 1200 UK small double?
Look for a frame sold as 4ft or UK small double, built for a 120 x 190cm mattress. A standard UK double frame will leave gaps at the sides, so check the frame's internal measurements before ordering. Compare the retailers listed on this page for current availability in this size.
