- Real space for one: At 120cm wide, a solo adult gets 30cm more width than a UK single, so you can sprawl without an elbow hanging off the edge.
- Fits rooms a double can't: Being 15cm narrower than a UK double often decides whether the door still clears or there's floor space left, useful in box rooms and studio flats.
- Edge support matters more at this width: The SupportCore sprung base holds firm right to the sides, which means you can use the full 120cm rather than avoiding the edges.
- Pressure relief for a lone side sleeper: Two layers of Aerocoil microsprings cushion shoulders and hips, so a solo side sleeper gets the softness a firmer compact mattress often lacks.
- Cool enough for a small room: Compact bedrooms can run warm, and the wool layer with graphite-infused foam helps the surface stay temperate through the night.
- Handles the occasional shared night: Across verified owner reviews motion transfer is minimal, so a couple sharing for a weekend visit won't wake each other with every turn.
This size suits you if...
You're a solo adult who has outgrown a UK single and wants room to stretch, but your bedroom, loft conversion or studio can't take a full double without losing walking space. It also fits if you're furnishing a guest room or rental second bedroom where couples stay a few weekends a year rather than nightly. Allow at least 2.4m x 2.8m of floor space, our suggestion, not Simba's.
Consider another size if...
You share the bed most nights, because 120cm is a squeeze for two regular sleepers on a medium mattress where you'll both settle in. We'd recommend the UK double instead, which adds 15cm of width.

Is a small double Simba Hybrid Pro big enough for a couple?
For occasional nights, yes. The minimal motion transfer owners report helps two people share without disturbing each other, and the firm sprung edges mean neither of you rolls off. For every night, 120cm is tight for two adults, and we'd point regular couples to the UK double instead.
Will the Simba Hybrid Pro small double fit in a box room?
Often, yes, and that's largely why this size exists. The mattress is 120 x 190cm (4ft x 6ft 3in), 15cm narrower than a UK double. We suggest a room of at least 2.4m x 2.8m so you can still open the door and walk down one side comfortably.
Is the small double a good upgrade from a single for a teenager?
It's a sensible step up. The 30cm of extra width over a UK single gives a growing teenager proper room to turn, and the medium feel with Aerocoil microsprings suits lighter bodies better than a very firm mattress would. The narrower footprint means the room keeps its floor space.
What bed frame do I need for this size?
A standard UK small double (4ft) frame, which takes a 120 x 190cm mattress. It's a common UK size, so frames and 4ft fitted sheets are easy to find. Check the frame supports the mattress edge to edge, as the Hybrid Pro's 28cm profile is on the deeper side.
Where can I buy the Simba Hybrid Pro in a small double?
Availability shifts, so the most reliable answer is the live price table on this page, which updates as retailers change their listings and prices. It's a less widely stocked size than the UK double or UK king, so comparing what's listed here before buying is worthwhile.
