Layer Details
Belgian Damask Viscose Sleep Surface
A silky, breathable damask cover, which means air can move through the sleep surface more easily. That helps the bed feel a little fresher through the night.
Silk
A light, soft silk layer sits near the top of the mattress. It adds a gentle, luxurious feel without trapping heat.
Sustainably Sourced British Wool
Wool gives cushioning with natural resilience, which means it springs back rather than compressing flat over time. It also regulates temperature well, a plus if you run warm.
Deep soft layer
A deeper soft layer adds extra cushioning between the natural fibres and the springs. It softens the initial feel when you lie down.
1000 Pocket Springs
Each spring sits in its own fabric pocket and moves independently, which means the mattress responds to your shape rather than pushing back as one unit. That gives better pressure relief and less motion transfer between partners.

Key benefits
- Real space for one: At 120cm wide, the UK small double is 30cm wider than the UK single, so a solo sleeper can stretch out and change position freely.
- Fits rooms a double crowds: It is 15cm narrower than the UK double, which can be the difference between a bed that fits a box room or loft conversion and one that dominates it.
- Same length as a single: The UK small double and the UK single are the same length at 190cm, so upgrading width doesn't cost you any extra room depth.
- Springs that work at this width: The 1,000 pocket springs move independently, so even on a narrower mattress you're supported at the hips and shoulders rather than rolling towards the middle.
- Natural fibres in a compact size: Silk and British wool sit above the springs, which means temperature regulation and a soft surface feel usually found on larger, pricier mattresses.
This size suits you if...
You sleep alone most nights and have outgrown a single, but your room can't take a full double without losing walking space. Or you're furnishing a guest room or holiday let where couples stay occasionally rather than nightly, and a 4ft bed keeps the room usable the rest of the time. It also suits a teenager who needs more width without giving up desk or floor space.
Consider another size if...
You share the bed every night and want proper room each. The medium firm feel is fine for two, but 120cm is snug for nightly sharing, so we'd recommend the UK double instead, which gives 67.5cm each and needs a room of at least 2.6m x 2.8m.

FAQ's
Is a small double Relyon Guildford 1000 big enough for a couple?
For occasional nights, yes. The pocket springs move independently, so one person turning over disturbs the other less than an open-coil bed would. For every night, 120cm across is tight for two adults, and we'd point regular sharers towards the UK double, which is 15cm wider and gives 67.5cm each.
What room size do I need for the Guildford 1000 in a UK small double?
We suggest a room of at least 2.4m x 2.8m. That leaves enough space to walk round the bed and open drawers or a wardrobe. If your room is smaller than that, measure carefully before ordering, particularly in loft conversions where sloping ceilings eat into usable floor area.
How much wider is the small double than a single?
The UK small double is 30cm wider than the UK single, and the two are exactly the same length at 190cm. In practice that extra width means a solo sleeper can lie on their side with arms out, or sit up reading, without hanging over the edge.
Will standard double bedding fit a 4ft small double mattress?
You'll need small double (4ft) fitted sheets, because standard double sheets will bag on a 120cm mattress. A standard double duvet works fine on top, though, so you only need to buy size-specific sheets rather than a whole new bedding set.
Should I choose the small double or size up to the UK king?
The UK king is 30cm wider and 10cm longer than the UK small double, and it needs a room of at least 2.7m x 2.9m. If you have that space and share nightly, the UK king gives 75cm each. If you sleep alone in a compact room, the small double is the more sensible fit.
