Layer Details
- Silk. A 270 GSM layer of silk sits at the top, which means a naturally breathable surface that helps move heat and moisture away from you. It gives the sleeping surface a softer, more luxurious first impression than the firm tension might suggest.
- Polyester. Beneath the silk is a 270 GSM polyester layer. It adds a little cushioning and helps the surface layers keep their shape over time.
- Reflex Soft foam. A 3-inch layer of Reflex Soft foam provides the main comfort padding. It softens the feel of the springs below, so you get pressure relief at the surface without losing the firm support underneath.
- Pocket springs with reflex foam. The base combines pocket springs with reflex foam and natural fillings. Each spring moves on its own, which means support adjusts to your weight across the mattress rather than as one rigid block.

- Leaves floor space free: At 3ft x 6ft 3in, the UK single fits a small child's bedroom and still leaves space for a wardrobe, a desk and somewhere to play on the floor.
- Suits raised frames: The UK single is the standard size for bunks, cabin beds and mid sleepers, although you should check the frame's maximum mattress depth against the 23cm depth first.
- Firm support for growing bodies: Individually moving pocket springs, which means support that adjusts to a child's changing weight and shape, suit younger sleepers who lie on their back or front.
- Two beds in one guest room: A pair of UK singles lets a spare room sleep two friends or siblings separately, and that flexibility is harder to get from one wider bed.
- Fits under a sloping ceiling: In a loft conversion, the narrow 90cm width lets the bed tuck along the low wall, so the taller part of the room stays usable.
This size suits you if...
You're furnishing a child's or teenager's room where the bed competes with storage and a desk, or you're fitting out a spare room that also works as a home office. It also suits you if you sleep alone, like a firm feel and have a compact room to work with.
Consider another size if...
You're an adult or older teen who sprawls and wants room to turn freely. We'd recommend the UK small double instead, which is 30cm wider; we suggest at least 2.4m x 2.8m for the UK small double.

What are the dimensions of the Sleep Story Natural Comfort Firm UK single?
The Sleep Story Natural Comfort Firm in a UK single measures 90 x 190cm, which is 3ft x 6ft 3in. It is 23cm deep, the same depth as the other sizes in the range. Standard UK single sheets and bedding will fit it.
Can I use the Sleep Story Natural Comfort Firm UK single on a cabin bed or mid sleeper?
The UK single is the size these raised frames are designed for, so the footprint should match. The thing to check is depth. This mattress is 23cm deep, and raised frames often set a maximum mattress depth for the safety rail to work properly, so confirm the frame maker's guidance before you buy.
How much bedroom space do I need for a UK single mattress like this one?
We suggest allowing at least 2.1m x 2.8m for a UK single. That leaves room to walk round the bed and open drawers. If two siblings share a room, plan for two beds plus a clear walkway between them, and measure before ordering.
Is a firm mattress in a single size a good idea for a child?
For many children, yes. Lighter bodies sink less into a mattress, so a firm surface tends to feel less hard to a child than to an adult. The one drawback is for a lightweight side sleeper, who may feel some pressure at the shoulders and hips, although the soft foam layer takes a little of the edge off.
Should I choose a UK single or UK small double Sleep Story Natural Comfort Firm for a guest room?
If you want to sleep two separate guests, two UK singles are more flexible. If one adult usually stays and you have the space, the UK small double is 30cm wider and the same length, and we suggest at least 2.4m x 2.8m for it. Compare the retailers listed on this page for current prices on each.
