Layer Details
- Upholstery. Entirely natural fillings of bonded and blended British fleece wool and cotton, encased in high-quality ticking, which means good breathability and a softer, more forgiving surface than synthetic alternatives. It is hand-tufted with felt washers, so the fillings are anchored in place and far less likely to shift or lump over time.
- Springs. A single layer of 1,558 hand-nested vanadium steel pocket springs in calico pockets, counted on the King size model. Each spring works independently, which means the mattress responds to your shape and reduces the ripple of movement from a partner turning over.

- Room to spread out alone: At 30cm wider than the UK single, you can sleep diagonally or starfish on the soft, pillowy surface without an arm dropping off the side.
- Fits a compact bedroom: Being 15cm narrower than the UK double, it leaves a little more floor clear in a small room, which can decide whether a wardrobe door still opens fully.
- Sensible for downsizing: If you are moving somewhere smaller, you can keep a proper double-style bed in natural fillings rather than dropping all the way to a UK single.
- Standard 4ft frame fit: It measures 4ft x 6ft 3in, a standard UK size, so finding a frame or headboard to match is straightforward.
- Cool for a solo warm sleeper: The wool and cotton fillings breathe better than synthetic foam, which helps in a small room where warm air tends to linger overnight.
This size suits you if...
You sleep alone but want more width than a UK single allows, your bedroom is compact or has a sloping ceiling that makes a UK double awkward, or you are furnishing a guest room where couples stay occasionally rather than every week.
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.

Is the Vispring Dartington Soft small double big enough for one adult?
For most solo sleepers, yes. The UK small double is 120 x 190cm, 30cm wider than the UK single, so there is space to shift position through the night. The length matches the UK single, though, so if you are very tall you may prefer the UK king, which is 10cm longer.
What size bedroom do I need for a Dartington small double?
We suggest allowing at least 2.4m x 2.8m for a UK small double. That leaves space to walk round the bed and open drawers. In a loft conversion, measure the full-height floor area rather than the whole room, since a sloping ceiling can make the usable space noticeably smaller.
Should I get the Dartington Soft in a small double or a double?
Choose the UK small double if you sleep alone or your room is tight, as it is 15cm narrower. Choose the UK double if two of you sleep together nightly: it gives 67.5cm each for two sharing, and we suggest at least 2.6m x 2.8m of room for it.
Is a small double Dartington a good choice for a guest room?
It suits a guest room well if visitors are mostly single, or couples staying a night or two. The soft tension and natural fillings feel welcoming for short stays. If regular guests are couples who stay for a week or more, the UK double would give them more comfortable space.
Will the Vispring Dartington small double fit a 4ft bed frame?
Yes. The UK small double measures 4ft x 6ft 3in, the standard UK 4ft size, so it is designed for 4ft frames and divan bases. Check the internal measurements of an older or antique frame before ordering, as some vary slightly from today's standard.
