Layer Details
- Quilted Cover. The cover and fillings are stitched together to form a patterned comfort quilt. This gives the sleep surface a gently cushioned, traditional feel from the moment you lie down.
- Advanced Comfort Foam. A breathable foam that contours to your body shape, which means tension relief where you sink in most. Being breathable, it should hold onto less heat than denser foams can.
- Open Coil Springs. Interlaced coils of high-tensile steel joined together in a lattice. Because the springs move as one connected unit, support is spread across the whole bed rather than responding point by point.

- Real room for one: At 120cm wide it's 30cm wider than a UK single, which means a solo sleeper can starfish without an elbow hanging off the edge.
- Fits compact rooms: It's 15cm narrower than a UK double, so it slots into box rooms, studios and loft conversions where walking space around the bed is tight.
- Soft feel suits solo sleepers: The comfort foam contours to hips and shoulders, and with no partner to share with, you get the full width of that cushioning to yourself.
- Copes with occasional sharing: The open coil unit moves as one piece, which two people will notice, but for the odd guest room night that's a fair trade at this price.
- Easy bedding and frames: The 4ft small double is a standard UK size, so fitted sheets and frames are simple to find, and a standard double duvet drapes generously.
This size suits you if...
You sleep alone and have outgrown a single but your room can't take a full double, you're furnishing a guest room or holiday let where couples stay occasionally rather than nightly, or you're downsizing and the bed now has to fit the new room's dimensions. In each case the soft feel and 120cm width give one person genuine comfort without dominating the floor plan.
Consider another size if...
You share the bed every night, because 120cm plus open coil springs means you'll feel each other's movement. We'd recommend the UK double instead: it gives 67.5cm each, and we suggest a room of at least 2.6m x 2.8m.

Is the Jasmine small double big enough for two adults?
For occasional nights, yes. For every night, we'd hesitate: 120cm is snug for two, and the Jasmine's interlaced open coils transfer movement across the bed, so you'll notice a partner turning over. If you share nightly, the UK double gives 67.5cm each and would suit you better.
What room size do I need for the Jasmine in a UK small double?
We suggest a room of at least 2.4m x 2.8m. That leaves enough clearance to open the door, walk down one side and change the sheets without a fight. In a box room or studio, that 15cm saving over a UK double is often what keeps the layout workable.
Should I get the Jasmine in a small double or a UK single?
If the room allows it, the small double. It's 30cm wider than the UK single at the same length, which is the difference between sleeping in one position and actually spreading out. A teenager who's outgrown a single often lands here, provided the room can spare the width. We suggest at least 2.1m x 2.8m for the UK single.
How does the small double Jasmine compare with the double?
The UK small double is 15cm narrower than the UK double, and both are the same length at 190cm. The mattress itself is identical: same soft feel, same 24cm depth, same open coil and foam construction. The choice comes down to who sleeps in it and how much floor space the room can give up.
Is a soft mattress a good choice at this size?
For a solo sleeper, usually yes. With the whole 120cm to yourself, you can settle into the contouring foam wherever suits you, and lighter sleepers in particular tend to get on with a softer surface. If you need firm back support, this mattress won't be right in any size.
