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.

- Fits compact rooms: At 90 x 190cm (3ft x 6ft 3in), it needs only around 2.1m x 2.8m of floor space by our guidance, leaving room for a desk or wardrobe.
- Grown-up support for a teen's bed: The medium firm feel with 1400 pocket springs gives a growing teenager proper support, rather than the basic foam slab many single beds get by default.
- A guest bed people actually sleep well on: The 5cm memory foam layer eases pressure on hips and shoulders, so occasional guests get genuine comfort rather than a token spare mattress.
- Cheap, easy bedding: Standard single sheets and a single duvet fit, and both are the most widely stocked and affordable bedding of any UK size.
- Airflow suits smaller rooms: The knitted cover and sprung core let air move through the mattress, useful in box rooms and loft spaces that can run warm.
This size suits you if...
You sleep alone and want memory foam comfort in the smallest standard adult footprint, you're buying for a child or teenager who has outgrown a basic foam mattress, or you're furnishing a spare room or student flat where the frame is already a single and the mattress is the missing piece.
Consider another size if...
You're an adult who spreads out at night, or you occasionally share the bed. The UK small double is 30cm wider at the same length, and we suggest at least 2.4m x 2.8m of floor space for it.

Is the Relyon Comfort Pure Memory 1400 UK single a good size for a child's room?
Yes, with one caveat. At 90 x 190cm it fits the typical child's bedroom while leaving space for toy storage and a desk, and the medium firm feel supports a growing back well. The caveat is the sink-in memory foam surface, which suits older children and teens better than very young ones moving up from a cot bed.
Will the UK single Relyon Comfort Pure fit a bunk bed or mid sleeper?
The width and length match standard bunk frames, but the depth is the issue. This mattress is 30cm deep, and most bunk and mid sleeper frames specify a much shallower maximum so the guard rail stays effective. Check your frame's maximum mattress depth before buying; for many raised beds this one will sit too high.
What room size do I need for the Relyon Comfort Pure Memory 1400 in a UK single?
We suggest at least 2.1m x 2.8m of floor space, which is our own guidance rather than Relyon's. That allows room to walk alongside the bed and open drawers or a wardrobe. It's a forgiving footprint, so this size works under a loft slope or in a spare room that also holds a desk.
Is a UK single big enough for an adult to sleep on every night?
For one average-sized adult, yes. At 90cm wide and 190cm long it's the standard UK one-person size, and the 1400 pocket springs support an adult's weight properly. Taller sleepers should note the 190cm length; if you're over six foot, the fit gets snug, though Relyon doesn't offer this mattress in a UK king.
