Key benefits
- Space to sprawl on your own: At 30cm wider than the UK single, a solo sleeper can turn over or sleep starfish-style without a knee or elbow ending up off the edge.
- Fits tighter bedrooms: We suggest allowing at least 2.4m x 2.8m, which brings a proper double-style bed within reach of many box rooms and smaller second bedrooms.
- Medium firm for one body: The medium-firm feel gives back sleepers steady support, which means one person gets consistent comfort across the surface rather than a dip in the middle.
- Springs that handle a second sleeper: Micro springs under the foam add support across the surface, so a guest couple staying a night or two gets more give-back than foam alone would offer.
- Easy bedding to find: The 4ft width is a standard UK size, so you can pick up fitted sheets in the shops without hunting for specialist sizes.
This size suits you if...
You sleep alone and want more room than a single gives, your bedroom can't comfortably take a 4ft 6in frame, or you're furnishing a guest room where couples stay occasionally rather than every night.
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; we suggest at least 2.6m x 2.8m for the UK double.

FAQ's
Can two adults sleep on a UK small double Blueberry Hybrid?
For a night or two, yes. The micro springs under the Serene foam give a guest couple support across the surface. For nightly sharing, though, the UK small double is snug, and most couples will sleep better on the UK double, which gives 67.5cm each for two sharing.
What size bedroom do I need for a Blueberry Hybrid small double?
We suggest at least 2.4m x 2.8m for a UK small double. That leaves you room to walk round the bed and open a wardrobe door. If your room is close to that minimum, measure where the door swings before you order.
Is a UK small double big enough for a teenager who has outgrown a single?
Usually, yes. The UK small double is 30cm wider than the UK single but the same length, so it suits a growing teenager who sprawls, while costing the room only a little extra floor. Check their height against the 190cm length if they're still shooting up.
Should I choose the small double or double Blueberry Hybrid for a guest room?
If guests are mostly single visitors with the occasional couple, the UK small double is enough and keeps the room open. It's 15cm narrower than the UK double and the same length. If couples stay often, the UK double is kinder to them, provided the room meets our suggested 2.6m x 2.8m.
Will a 4ft Blueberry Hybrid work in a loft conversion?
Often it's the better choice there. A sloping ceiling limits where you can stand beside the bed, and the UK small double's narrower width keeps a usable strip of headroom along one side. Measure the stairs and the turn at the top first, then compare the retailers listed on this page.
