Layer Details
Cover
A sumptuously soft natural cover, designed for enhanced breathability. In practice, that means air can move through the sleep surface rather than trapping heat against you.
Wool
Fully traceable Black Country wool that regulates temperature. Wool wicks moisture and buffers heat, so you should feel more even in temperature through the night.
Fibres
Recyclable, air-blown fibres that give the feel of a million micro springs. This creates a cushioned, responsive surface layer above the main spring unit.
Pocket Springs
Individually encased pocket springs that adapt to your body's movements to minimise disturbance to your partner, while supporting your back and hips. Each spring moves on its own, so one person turning over is less likely to jolt the other.

- Fits compact rooms: At 3ft x 6ft 3in, the UK single leaves room for a desk, wardrobe and toy storage in a child's bedroom rather than swallowing the floor.
- A depth that suits raised frames: The 22cm depth sits well within the safety rail limits of most bunk and mid-sleeper frames, where a taller hybrid can leave the rail too low.
- Wool that helps warm sleepers: Black Country wool regulates temperature, which means a teenager who runs hot is less likely to wake up clammy.
- Easy to flip on your own: The Elsham is double-sided, and the UK single is the easiest size to turn without help, so evening out wear is a one-person job.
- Cheap, easy bedding: Single sheets and duvets are the most widely stocked and least expensive of any UK size, handy for guest rooms and student flats.
This size suits you if...
You're buying for a child or teenager moving up to a proper sprung mattress, you sleep alone in a compact room or loft conversion where only a narrow footprint fits, or you're kitting out a spare room or student flat and want natural materials at a mid-range price. The medium tension suits growing bodies and occasional guests alike.
Consider another size if...
You're an adult who shares the bed, or a restless solo sleeper who wants space to spread out. The Elsham's pocket springs reduce partner disturbance, so we'd recommend the UK double instead; allow at least 2.6m x 2.8m for it.

Will the Elsham UK single fit a bunk or mid-sleeper frame?
In most cases, yes. The UK single measures 90 x 190cm, the standard size for bunk and cabin frames, and at 22cm deep the Elsham should sit below the safety rail on most raised beds. Check your frame's maximum mattress depth before buying, as some bunks specify a lower limit.
Is the Elsham single a good mattress for a child or teenager?
It's a sensible fit. The medium tension pocket springs support growing backs and hips without feeling hard, and the wool layer helps regulate temperature for kids who overheat at night. It's also double-sided, so flipping it regularly should help it last through the teenage years.
How much floor space does a UK single Elsham need?
We suggest allowing at least 2.1m x 2.8m of floor space, which gives you room to walk around and change the bedding. The mattress itself is 90 x 190cm, so it works in box rooms, under loft slopes and in spare rooms that double as an office.
Can two Elsham singles work in a shared kids' room or guest room?
Yes, and it's a common setup. Each UK single is 90cm wide, so two beds plus a walkway fit in a reasonably sized shared bedroom, and the pocket springs mean each sleeper's movement stays on their own bed. For guest rooms, two singles offer more flexibility than one double.
Should I choose the single or the small double for a solo adult?
It depends on your room and how much you move at night. The UK single is 30cm narrower than the UK small double, and the two are the same length. If you have at least 2.4m x 2.8m of floor space and like room to sprawl, the UK small double is the more comfortable long-term choice.
