Key benefits
- Real room for one: At 30cm wider than the UK single, you can change position freely, which matters on a slow-response foam that moulds around you as you settle.
- Fits compact double bedrooms: It's 15cm narrower than the UK double, often the difference between a bed you can walk around and one you have to squeeze past.
- Firm support at any size: The extra firm, contouring feel of TEMPUR Advanced Material is identical here to the larger sizes, so a smaller footprint doesn't mean a compromised mattress.
- Handles occasional sharing: A guest room small double copes with couples staying a few weekends a year, and the low motion transfer of dense foam helps two people share without disturbance.
- Standard 4ft bedding: Small double is a standard UK size, so fitted sheets and frames are easy to find, and the 25cm depth sits within most fitted sheet ranges.
This size suits you if...
You sleep alone and have outgrown a single but can't spare the floor space a full double takes, or you're furnishing a box room, loft conversion or small second bedroom where 120cm of width is the sensible maximum. It also suits a guest room that hosts couples occasionally rather than every night, since the firm foam handles two people comfortably for short stays.
Consider another size if...
You share the bed every night, because 120cm across two adults feels tight on a mattress this firm, where you settle in rather than roll about. We'd recommend the UK double instead, or the UK king if the room allows.

FAQ's
Is a small double Tempur Pro Plus SmartCool Firm big enough for a couple?
For occasional nights, yes. Across a 120cm width two adults will be close together, and because the firm TEMPUR Advanced Material moulds around you rather than letting you shuffle freely, nightly sharing feels cramped. For a guest room hosting couples a few weekends a year it works well; for every night, size up.
What room size do I need for a small double mattress?
We suggest allowing at least 2.4m x 2.8m. That leaves enough space to open the door, walk around the bed and get in from the side. In a box room or studio, measure before you buy: the 15cm saved against a UK double is often what keeps the layout workable.
What bedding fits the Tempur Pro Plus SmartCool Firm in a small double?
Small double (4ft) fitted sheets with a standard double duvet. The mattress is 25cm deep, which most standard fitted sheets accommodate, though it's sensible to check the sheet's stated depth before ordering. The QuickRefresh cover is removable, which makes freshening the surface underneath your bedding straightforward.
Is the small double a good choice for a teenager?
Often, yes. It gives a growing teenager 30cm more width than a UK single without swallowing the whole room. Bear in mind this is a firm, slow-response foam, quite a solid feel, so it suits a teenager who sleeps on their back or front better than a lightweight side sleeper.
