Layer Details
- Knitted cover with Microquilted finish. A soft knitted cover with a micro-quilted finish, which means a smooth surface with a little extra cosiness and warmth. It's the first thing you'll feel, and it adds a gentle, cushioned touch.
- Soft White Fibres. Soft synthetic polyester fillings sit beneath the cover, wrapping around your shape and easing pressure at the hips and shoulders. The brand describes them as durable and resilient, designed to hold their shape over time.
- Pocket Springs. 1000 pocket springs, each sewn into its own fabric pocket so they move independently. This means support goes where your body needs it most, and movement on one side of the bed transfers less to the other.

- Real stretching room for one: At 120cm across, a solo sleeper gets generous space to shift position through the night without teetering near an edge.
- Fits rooms a double overwhelms: The UK small double is 15cm narrower than the UK double, which can be the difference between a door that clears the frame and one that doesn't.
- 1000 independent springs across 4ft: Each spring sits in its own pocket, so the mattress follows your shape rather than sagging towards the middle where one person always lies.
- Soft, cushioned surface: The micro-quilted knitted cover and soft fibre fillings give a gentle, huggy feel that suits lighter solo sleepers settling into one spot.
- Standard UK size for bedding: 4ft is a recognised UK size, so small double fitted sheets and frames are easy to find on the high street.
This size suits you if...
You're a solo adult, or a teenager who has outgrown a single, and you want more width without giving up the floor space a bigger bed would swallow. It also fits a box room, studio flat or loft conversion where a standard double leaves no room to stand, or a guest room where couples stay occasionally rather than nightly.
Consider another size if...
You share the bed every night, since 120cm is a squeeze for two adults long term, especially on a softer mattress where you may drift together. We'd recommend the UK double instead; allow at least 2.6m x 2.8m for it.

Is a small double big enough for one adult to spread out on?
Yes, comfortably. The UK small double is 30cm wider than the UK single at the same 190cm length, so a solo sleeper gets meaningful extra width for stretching out or changing position. On this mattress the 1000 pocket springs respond to where you actually lie, so you get support wherever on that width you settle.
Will the Bodyshape Boost 1000 small double work for a couple?
For occasional nights, yes; for every night, we'd hesitate. At 120cm wide, two adults get noticeably less personal space than on a UK double, and this mattress has a soft, cushioned feel that some couples find lets them roll towards each other. As a guest room bed for visiting couples, it's a sensible choice.
What room size do I need for a small double mattress?
We suggest at least 2.4m x 2.8m for a UK small double, which leaves room to walk around the bed and open drawers. The mattress itself is 120 x 190cm, or 4ft x 6ft 3in. In a loft conversion or box room, measure where the ceiling slopes and where the door swings before you commit.
Is the small double the same length as a single?
Yes. The UK small double and the UK single are both 190cm long; the small double is simply 30cm wider. That makes it a natural next step for a teenager who has outgrown a single, since the bed grows sideways rather than eating into the length of the room.
Is this a good size for a guest room or rental?
It's one of the better options. The UK small double gives visiting couples enough space for a short stay, yet fits second bedrooms and holiday lets where a full double would crowd the room. The soft feel of the Boost 1000 divides opinion among owners, though for occasional guests rather than nightly use that matters less.
