Layer Details
- Damask cover. A finely woven, durable fabric that's soft to the touch and doesn't retain heat, which means it should stay comfortable on warmer nights. It's built for long-lasting performance rather than a plush pillow-top feel.
- Soft White Fibres. Soft synthetic fillings that add a cosy layer over the firmer materials beneath. They're durable and resilient, designed to hold their shape over time rather than flattening quickly.
- Dual density polyester pad. Plush on one side and densely packed on the other, this pad reinforces the firm feel of the mattress. In practice it means you get a small amount of surface softness without losing that solid support underneath.
- Pocket Springs. 1,000 individual springs, each encased in its own cloth pocket, adapt to your movement independently. That means support is distributed to each part of your body, and your partner's movements are less likely to disturb you.

- Real space for one: At 30cm wider than the UK single, you can stretch out, roll over and change position without your elbows finding the edge.
- Fits rooms a double won't: Being 15cm narrower than the UK double can be the difference between a door that clears the bed and one that doesn't.
- Firm support in a compact footprint: The 1,000 individual pocket springs respond to each part of your body separately, so a solo sleeper gets even, stable support across the full width.
- Copes with occasional sharing: When a guest brings a partner, the pocket springs limit roll-together, which makes the odd shared night workable even at this width.
- Breathable cover for smaller rooms: The damask cover doesn't hold heat, useful in a loft or box room that warms up quickly in summer.
This size suits you if...
You sleep alone, like a firm feel, and have outgrown a single but can't spare the floor space a double demands. It also fits if you're furnishing a guest room or small second bedroom in a rental or holiday let, where couples might share for a night or two but nobody sleeps there every night. Allow a room of at least 2.4m x 2.8m.
Consider another size if...
You share the bed every night, because 120cm across two adults feels tight quickly on a firm mattress. We'd recommend the UK double instead, which gives 67.5cm each; allow a room of at least 2.6m x 2.8m.

What are the dimensions of the Relyon Prairie 1000 small double?
The UK small double measures 120 x 190cm, or 4ft x 6ft 3in. That's 30cm wider than the UK single and the same length, so a taller sleeper gains no legroom by choosing it, but a lot of extra width. Small double frames and 4ft fitted sheets are standard UK sizes, so both are easy to find.
Will the Relyon Prairie 1000 small double fit in a box room?
Usually, yes, and that's much of this size's appeal. We suggest a room of at least 2.4m x 2.8m, which leaves enough space to walk round the bed and open the door properly. Measure the wall the bed will sit against before ordering, and check the route in: stairs and landings catch people out more often than the room itself.
Is the small double Relyon Prairie 1000 big enough for one adult?
Comfortably. At 120cm wide it's 30cm wider than the UK single, which means room to spread out, shift position and sleep diagonally if that's your habit. The firm pocket spring construction supports you evenly wherever you settle on the surface, although lighter side sleepers may find the feel slightly solid at the shoulders and hips.
Is this a good size for a guest room?
For a room hosting occasional guests rather than nightly sleepers, yes. Two people can share for a weekend, and the individual pocket springs reduce the movement each person feels from the other. The firm feel divides opinion among guests used to softer beds, but for a few nights that matters far less than it would every night.
