Layer Details
- Wool. A soft wool top layer that's naturally breathable, which means air can move freely rather than trapping heat around you. Wool also wicks moisture, a quiet advantage on warmer nights.
- Natural fillings blend. Layers of wool and hemp blended with fibres, giving a soft, springy feel underneath you. These natural fillings help regulate temperature through the night.
- HD mini springs. 1700 of Harrison Spinks' own HD mini springs sit above the main unit, flexing to mould to your body's shape. In practice this means more precise, three-dimensional support around shoulders and hips.
- Pocket Springs. The base unit is 2750 pocket springs, each moving independently, so the mattress adapts to your body rather than sagging as one piece. Independent movement also reduces the ripple you feel when a partner shifts.

- Fits where space is tight: At 90cm wide, this single leaves room for a desk, wardrobe and toy storage in a child's bedroom, or two beds plus a walkway where siblings share.
- Grown-up support for growing sleepers: The firm pocket spring feel gives children and teens consistent support through years of growth, rather than a soft surface they sink into.
- Natural fillings suit warm sleepers: Wool and hemp fillings breathe better than synthetic foam, which means a teenager's small, warm room is less likely to feel clammy at night.
- A guest bed people remember kindly: In a spare room that doubles as an office, a single this well made means guests get proper support without the bed dominating the floor.
- Loft and awkward rooms welcome: The narrow 90cm footprint tucks under a sloping ceiling or into a boxroom where a UK double simply would not go.
This size suits you if...
You're buying for a child or teenager and want a supportive, natural-filled mattress that will last through their growth, you sleep alone and prefer a firm feel in a compact room, or you're furnishing a spare room or student flat where a 90cm-wide bed keeps the rest of the space usable.
Consider another size if...
You share the bed, or you're a broad-shouldered adult who finds 90cm restrictive. We'd recommend the UK double instead: it's 45cm wider than the UK single and the same length, and we suggest at least 2.6m x 2.8m of floor space for it.

Will the Bordley Natural 2750 UK single fit a bunk or mid sleeper frame?
The width and length match standard UK single frames, so it will fit bunks, cabin beds and mid sleepers. Check depth carefully though: at 25cm, this mattress is deeper than many bunk-specific designs, and on a top bunk the safety rail must still sit well above the mattress surface. Measure your frame's maximum mattress depth first.
What room size do I need for a UK single Bordley Natural 2750?
We suggest at least 2.1m x 2.8m of floor space for a UK single. That leaves enough room to walk around the bed and open drawers or a wardrobe. In a child's room competing with a desk and toy storage, or a loft room with a sloping ceiling, the 90 x 190cm footprint is the easiest size to work around.
Is a UK single big enough for an adult?
For one adult, yes, though 90cm of width is snug if you're broad-shouldered or move about at night. The firm feel of the Bordley Natural 2750 helps here, as you sleep on the surface rather than sinking into it. If your room allows, the UK small double is 30cm wider than the UK single and the same length, and we suggest at least 2.4m x 2.8m for it.
Is the firm feel of this single suitable for a child?
Generally yes. A firm pocket spring mattress supports a growing spine well, and children are light enough that the 2750 pocket springs and 1700 HD mini springs will still flex to their shape. Lighter side sleepers may find it slightly unyielding at first, so expect a short adjustment period.
Should I buy the UK single or size up to the UK double?
For a child's room, guest room or anywhere space is tight, the UK single makes sense. If the room is for a couple or an adult who wants space to spread out, the UK double is 45cm wider than the UK single, the same length, and needs at least 2.6m x 2.8m of floor space by our guidance.
