Layer Details
Probiotic top layer
The top layer has a probiotic fabric treatment (Bio-Protect), described as a 100% natural treatment to protect against allergens. If allergens are a worry for you, that gives the surface a bit of extra protection.
Comfort layer
A comfort layer of fillings sits under the soft knitted, micro-quilted cover and adds softness to the surface. It takes the edge off the springs below, though the feel stays medium firm overall.
Pocket spring core
The core has 1,000 individually pocketed Posturepocket springs, which provide the main structure and support. Because each spring moves on its own, the mattress follows your shape and passes less movement across to a partner. The 1,000 figure is given for King size, so it may differ in other sizes.
Edge springs
Two firmer rows of pocket springs run around the outer edges. They give support right to the sides, so sitting on the edge or sleeping near it should feel steadier.

Key benefits
- Real room for one: At 30cm wider than the UK single, it gives a solo adult space to shift position freely, which the independent pocket springs then support wherever you land.
- Fits the awkward room: Being 15cm narrower than the UK double, it can be the difference between a door that clears and one that doesn't in a box room or loft conversion.
- Copes with occasional sharing: When guests stay as a pair, the pocket springs move independently, so one person turning over disturbs the other less than an open coil build would.
- A settled feel for restless solo sleepers: The medium firm tension keeps you supported rather than sinking, which suits back and combination sleepers who move about at night.
- Easy to dress: 4ft is a standard UK size, so small double fitted sheets and frames are simple to find, and a standard double duvet works on top.
This size suits you if...
You're a solo adult, or a teenager who has outgrown a single, and you want more width to stretch out without the bed swallowing the room. It also fits if you're furnishing a guest room or holiday let where couples stay for the odd night rather than every night, or you're downsizing and the bed has to fit the new room's dimensions, not the old one's.
Consider another size if...
You share the bed every night, because 120cm is a squeeze for two adults long term. We'd recommend the UK double instead, which gives 67.5cm each for two sharing; allow at least 2.6m x 2.8m of floor space for it.

FAQ's
Is a small double big enough for the Relyon Comfort Pure 1000 to suit two people?
For occasional nights, yes. The pocket springs respond to each sleeper separately, so a visiting couple will sleep reasonably well for a weekend. Every night is another matter: at 120cm wide it's a snug fit for two adults, and the UK double or UK king of this mattress would serve a full-time couple far better.
What room size do I need for the Relyon Comfort Pure 1000 in a small double?
We suggest allowing at least 2.4m x 2.8m. That leaves enough clearance to walk around the bed and open drawers or a wardrobe, which is exactly where this size proves useful: it slots into box rooms, studio flats and loft conversions where a UK double would leave no standing room alongside.
How much wider is the small double than the single in this mattress?
The UK small double is 30cm wider than the UK single, and the two are the same length at 190cm. That extra width is the whole point for a solo sleeper: room to spread out and change position without hanging an arm off the edge, while the footprint stays manageable in a smaller bedroom.
Does the small double feel firmer or softer than other sizes?
No, the feel doesn't change with size. Every size of the Relyon Comfort Pure 1000 uses the same medium firm pocket spring build, so the small double feels the same as the UK double or UK king. What changes is space, and on a small double a solo sleeper gets plenty of it.
What bedding fits the small double version?
You'll need small double (4ft) fitted sheets, which are widely stocked since 4ft is a standard UK size. For the top layer, a standard double duvet works well and gives a little generous overhang on each side. Avoid single sheets and double sheets alike; neither fits the 120 x 190cm footprint properly.
