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.

- A firm mattress that fits small rooms: At 90cm wide it leaves floor space free for a wardrobe, desk or toy storage, which matters when the bed is competing for every inch.
- Solid support without sharing compromises: The 1,000 pocket springs respond to your body independently, and in a single that support is all yours, with no need to balance two sleepers' preferences.
- Suits a spare room that earns two uses: A firm single is easy to place against a wall in a room that doubles as an office, keeping a proper bed ready for guests.
- The cheapest bedding of any size: Standard single sheets and a 135 x 200cm single duvet fit, and both are the most widely stocked bedding in UK shops.
- Cooler in warm little rooms: The damask cover doesn't retain heat, a quiet plus in a small bedroom or loft space that warms up quickly on summer nights.
This size suits you if...
You're buying for a child or teenager's room where the bed shares space with a desk and storage, you're furnishing a spare room or first flat and want a proper firm mattress in the smallest standard footprint, or you sleep alone and know you prefer a firm, stable feel over a soft one.
Consider another size if...
You're an adult who spreads out at night, or anyone might share the bed even occasionally. We'd recommend the UK double instead: it's 45cm wider than the UK single, gives 67.5cm each for two sharing, and needs a room of at least 2.6m x 2.8m.

What size room do I need for the Relyon Prairie 1000 in a UK single?
We suggest allowing at least 2.1m x 2.8m of floor space. That's our guidance rather than Relyon's, and it leaves enough room to walk around the bed and open drawers or a wardrobe. The mattress itself measures 90 x 190cm, so it remains one of the easiest sizes to place, even under a loft slope.
Is the UK single Relyon Prairie 1000 long enough for a tall adult?
The UK single is 190cm long, the same length as the UK small double and UK double. If you're tall enough to feel cramped at that length, the UK king and UK super king are both 10cm longer, though they need considerably more floor space and a bigger room.
Is the Relyon Prairie 1000 single a good choice for a child?
The single is the standard UK size for children's and teenagers' rooms, and the pocket spring construction gives stable, even support. Bear in mind this is a firm mattress. Lighter children who sleep on their side may find it a little solid at the shoulders and hips, and some owners add a topper to soften the surface.
Should I buy a UK single or a UK small double for one person?
The UK single is 30cm narrower than the UK small double, and both are the same length. If the room allows, an adult sleeping alone often appreciates the extra width; we suggest at least 2.4m x 2.8m for the UK small double. For a child's room or a tight spare room, the single is the safer fit.
