Key benefits
- Real room to spread out: At 120cm wide, it's 30cm wider than a UK single, which means a solo sleeper can change position freely without hanging an arm off the edge.
- Fits where a double won't: It's 15cm narrower than a UK double, so it suits box rooms, studio flats and loft conversions where every centimetre of floor space matters.
- Modest room requirement: We suggest a room of at least 2.4m x 2.8m, which is smaller than any double-width size asks for.
- Memory foam suits solo cradling: The slow, sink-in feel works best when one person settles into the centre, which is exactly how most small double owners use it.
- Standard 4ft bedding: The UK small double is a standard UK size, so small double fitted sheets and frames are easy to find on the high street.
This size suits you if...
You sleep alone and have outgrown a UK single but your room can't take a full double, you're furnishing a box room, loft conversion or studio where a 135cm frame would block the door or leave no standing room, or you're setting up a guest room where couples stay occasionally rather than every night.
Consider another size if...
You share the bed with a partner every night, since 120cm is a squeeze for two on a nightly basis. We'd recommend the UK double instead, which gives 67.5cm each and needs a room of at least 2.6m x 2.8m.

FAQ's
What are the dimensions of the Nectar Classic in a UK small double?
The UK small double measures 120 x 190cm, or 4ft x 6ft 3in. That's the same length as a UK single but 30cm wider, so you gain sprawling room without needing a longer bed frame.
Will the Nectar Classic small double fit in a box room?
Usually, yes. We suggest a room of at least 2.4m x 2.8m for a UK small double, which leaves enough space to walk around the bed and open the door. Measure your room before ordering, and remember wardrobes and radiators eat into that allowance.
Is the Nectar Classic small double big enough for two people every night?
For occasional stays, such as guests or the odd weekend together, it works. For nightly sharing it's tight, and memory foam's cradling feel means you'll notice the squeeze. Couples sharing every night would do better with the UK double, which gives 67.5cm of width each.
Is the small double Nectar Classic a good upgrade from a single?
It's a sensible one. You get 30cm of extra width, and because the UK small double and the UK single are the same length, your room only needs to absorb width, which makes it a popular step up for teenagers or adults who've outgrown a 3ft bed.
Where can I buy the Nectar Classic small double at the best price?
Compare the retailers listed on this page. The prices shown here are updated as retailers change them, so checking the live table is more reliable than any figure we could print. Stock of the UK small double can vary, since it's a less common size than the UK double or UK king.
