Layer Details
- Knitted cover. A soft knitted finish that adds a touch of cosiness, which means the surface feels inviting rather than clinical. Knitted covers are breathable and help air move through the sleep surface.
- Memory Foam. A 5cm layer of memory foam that moulds to your shape, which means pressure is lifted from your hips and shoulders as you settle in. Expect a gentle sink-in feel rather than sleeping on top of the mattress.
- Soft White Fibres. A dense layer of soft synthetic fillings that adds cosy comfort while reinforcing the medium to firm feel. It also works as an insulator pad, protecting you from feeling the spring unit beneath.
- Pocket Springs. A core of 1400 pocket springs, each in its own fabric pocket, adapts to your movement through the night. Because the springs move independently, you and a partner are less likely to disturb each other.
Layer details from mattressonline.co.uk product page, September 2026.
- Real space for one: The UK small double is 30cm wider than the UK single, so a solo adult can shift position freely without a foot drifting off the edge.
- A double bed for a compact room: At 120cm wide it fits box rooms, loft conversions and small second bedrooms where a standard double would block walkways or stop the door clearing.
- Springs that suit occasional sharing: The 1400 pocket springs move independently, which helps when a guest room bed occasionally hosts two people at closer quarters than a full double allows.
- Pressure relief without the heat: The 5cm memory foam layer cradles hips and shoulders, while the sprung core and knitted cover let air move more freely than an all-foam build.
- Standard 4ft fittings: Small double is a standard UK size, so frames, fitted sheets and protectors are easy to find, and a standard double duvet works fine on top.
This size suits you if...
You're a solo adult who has outgrown a single and wants room to stretch, or you need a double bed in a bedroom that a 4ft 6in frame would swamp. It also suits a guest room or holiday let where couples stay occasionally rather than nightly. Allow at least 2.4m x 2.8m of floor space so you can still move around the bed comfortably.
Consider another size if...
You share the bed every night and want proper space each. Relyon doesn't make this mattress in a UK double or king, so we'd recommend the UK super king instead, which gives 90cm each; allow at least 3m x 2.9m.

Is the Relyon Comfort Pure Memory 1400 small double big enough for two adults?
For occasional nights, yes. At 120cm wide, two sharing get noticeably less space than a standard double, though the 1400 pocket springs move independently, which softens the effect of a partner turning over. For every night as a couple, this range jumps straight to the UK super king, which gives 90cm each.
What room size do I need for a small double mattress?
We suggest a room of at least 2.4m x 2.8m for a UK small double. That leaves enough space to open the door fully, walk down one side of the bed and fit a slim bedside table. In a box room or studio, measure the clear floor after wardrobes before you commit.
Does the Relyon Comfort Pure Memory 1400 come in a UK double?
No. Relyon makes this mattress in a UK single, UK small double and UK super king only. If you had a UK double in mind, the small double is 15cm narrower and the same length, which is often close enough for one sleeper, or a comfortable squeeze for a couple on occasional nights.
How much bigger 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 difference between sleeping in one fixed position and being able to sprawl, which matters with memory foam, since you'll want room to settle into the 5cm top layer.
