Layer Details
- Quilted Cover. The cover is stitched together with the fillings beneath it, creating a patterned comfort quilt layer. In practice, that means the soft surface feel is built in rather than sitting loose on top.
- Wool. Deep layers of plush wool cushion your body at every point of contact. Wool insulates well, keeping you warm and snug, while its breathable structure helps prevent overheating.
- Pocket Springs. Each spring sits in its own fabric pocket and moves independently, a little like piano keys. This targets pressure relief precisely, adjusting to your movements and how your weight is distributed.

- Space to spread out alone: At 30cm wider than the UK single, you can sleep on your side with knees drawn up and still have room to turn without meeting the edge.
- Fits a compact bedroom: Being 15cm narrower than the UK double, it leaves a little more floor for a door swing, a wardrobe or a narrow bedside table.
- Softness suits a solo side sleeper: The deep wool fillings let your shoulder and hip sink in slightly, which means a single sleeper with the whole width can settle wherever feels comfortable.
- Gentle on guests who share: Individually pocketed springs move independently, which means a couple staying the odd night should feel less of each other turning over.
- Warm without stuffiness in small rooms: Wool is breathable as well as insulating, which helps in a snug box room or loft conversion where warmth tends to collect.
This size suits you if...
You sleep alone and want a softer, cushioned bed with real room to stretch, and your bedroom is too tight for a UK double, or the bed mostly hosts guests who share it only now and then.
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 that room.

Will the Spring King Wool Luxury Soft 3000 small double fit in a box room?
The UK small double measures 120 x 190cm, or 4ft x 6ft 3in. We suggest a room of at least 2.4m x 2.8m, which leaves space to walk round the bed and open the door. If your room is tighter than that, measure the door swing and any wardrobe doors before you order.
Is a small double Spring King Wool Luxury Soft 3000 a good upgrade for a teenager?
For a teenager who has outgrown a single, the UK small double adds 30cm of width without taking the floor space a UK double would. The length stays the same as a single, so a very tall teenager may still reach the end. The soft wool feel suits growing side sleepers who like to sink in a little.
Can a couple share the Spring King Wool Luxury Soft 3000 in a UK small double for guest stays?
For a night or a weekend, yes. It will feel close, but the pocket springs move independently, so one guest turning over disturbs the other less. For a couple sleeping together every night, the UK double gives 67.5cm each for two sharing and is the more comfortable choice.
Small double or double Spring King Wool Luxury Soft 3000 for one person?
If you sleep alone, the UK small double gives plenty of width, and the UK double is 15cm wider again. Choose the UK small double when floor space is tight or the room is under 2.6m x 2.8m, which we suggest for the UK double. With space to spare, a UK double simply gives a solo sleeper more room to sprawl.
Does the Spring King Wool Luxury Soft 3000 small double suit a loft conversion?
It can work well, as the narrower 120cm width helps where sloping ceilings leave little headroom beside the bed. Measure the stretch of floor with full standing height, as well as the stairs, before buying. The breathable wool also suits loft rooms, which often run warm in summer.
