Comfort fillings
A blend of silk and polyester fibres sits at the surface. It gives the top a soft, comforting feel over the firmer layers below.
Additional fillings
Soft white fibres and a polyester and cotton blend add breathability and cosy comfort. That helps the surface feel cushioned without losing air flow.
Polyester fibre pad
A densely packed polyester fibre pad finishes the build. It adds to the firm feel, so the mattress stays supportive.
Pocket spring core
A core of 1000 individual pocket springs, each in its own fabric pocket. The springs move independently, so the mattress supports you closely across its surface.

Key benefits
- Room to spread out alone: At 120cm wide, 30cm more than a UK single, a solo sleeper can stretch out or sleep with knees bent without hitting an edge.
- Fits where a double won't: We suggest a room of at least 2.4m x 2.8m, so the UK small double can suit a box room where a UK double would crowd the doorway.
- Steadier edges on a narrower bed: The Calibar Edge uses firmer outer springs, so sitting or lying near the side should feel steadier, which helps when a 4ft mattress leaves less spare width.
- Firm support with a gentler top: The pillow top adds a little cushioning above the springs, so back and front sleepers get firm support without a harsh surface, though the rating stays firm.
- Straightforward to dress: 4ft is a standard UK size, so small double fitted sheets are easy to find; pick deep pockets, because this mattress is 36cm deep.
This size suits you if...
You sleep alone and keep ending up at the edge of a single, or your bedroom simply can't spare the floor space for a UK double. It also suits a guest room where couples stay for the odd night rather than every night.
Consider another size if...
You share the bed every night with a partner. We'd recommend the UK double instead, which gives 67.5cm each; allow at least 2.6m x 2.8m for it.

FAQ's
Is a UK small double Relyon Cerrado Pillowtop big enough for two?
For an occasional night, most couples will manage. Every night, it can feel tight, and the UK double is 15cm wider. The 1000 springs move independently, so one person turning over is less likely to shift the whole surface, but that doesn't make up for the narrower width.
What room size do I need for a Relyon Cerrado Pillowtop UK small double?
We suggest a bedroom of at least 2.4m x 2.8m. That leaves room to walk round the bed and open the door. In a loft conversion, check where the ceiling slopes first: you'll want the full-height part of the room beside the bed, so you can stand up when you get out.
What sheets fit a UK small double Relyon Cerrado Pillowtop?
Look for small double (4ft) fitted sheets, which are easy to find in UK shops. Check the pocket depth, though. At 36cm deep with a pillow top, this mattress can pull shallow sheets off the corners, so a deep-pocket fitted sheet is the safer buy. A standard double duvet gives you generous overhang.
Is the Relyon Cerrado Pillowtop UK small double good for a teenager moving up from a single?
It can be, if they sleep on their back or front. The UK small double is 30cm wider than a UK single but the same length, so it takes less floor than a UK double. Lighter side sleepers may find the firm rating gives too little at the shoulders and hips.
Should I get the Relyon Cerrado Pillowtop in a small double or a double?
Choose the UK small double if you sleep alone or the room is under 2.6m x 2.8m. Choose the UK double if two of you share most nights: it is 15cm wider, giving 67.5cm each, and the same length. Both sizes have the same firm feel and pillow top.
