Layer Details
Pocket springs
1000 Cortec Quad Revolution springs sit in cloth pockets and are grouped in fours, with mini springs inside the regular springs. This is the main support layer, so it is what gives the mattress its firm, held-up feel.
Mini pocket springs
A layer of 1000 Posturfil springs, plus an extra 7500 mini springs, sits above the main springs for contouring. It adds some shape-following give on top of the firm support below.
Wool, hemp and flax blend layer
Layers of wool, hemp and flax are blended to improve breathability. Air can move through the mattress more easily, which helps if you tend to feel the heat at night.
Cotton, hemp and flax layer
An extra layer of cotton, hemp and flax wicks moisture away. That should help the surface feel drier and fresher while you sleep.
Wool comfort layer
The top layer is 100% traceable British wool, which gives a plush surface. It softens the feel at the top, though the mattress overall is still firm.

- A compact footprint for tight rooms: At 90cm wide, this mattress leaves floor space free in a spare room doubling as an office or a bedroom already busy with a desk and wardrobe.
- Firm support for one sleeper: The firm feel holds a solo back or front sleeper level rather than letting them sink, which many people find easier for getting in and out of bed.
- Pocket springs that respond to you alone: Each spring compresses independently, which means the surface follows your shape rather than dipping as one solid slab.
- A sensible fit for guest rooms: Two UK singles suit a guest room better than one larger bed, giving visitors their own space without dominating the room.
- Traditional build in the everyday size: Harrison Spinks sits at the hand-built end of the market, so this is the smallest and least expensive way into that construction quality.
This size suits you if...
You sleep alone and prefer a bed that supports you firmly rather than cradling you, or you're kitting out a guest room, student room or first flat where a frame is already waiting for a mattress. It also suits a compact bedroom where every centimetre of floor space matters, provided the sleeper is happy with a firm feel rather than a soft one.
Consider another size if...
You're an adult who feels hemmed in at 90cm wide, or you occasionally share the bed. We'd recommend the UK double instead: it's 45cm wider than the UK single, the same length, and we suggest at least 2.6m x 2.8m of floor space for it.

What room size do I need for the Gold 9500 in a UK single?
We suggest allowing at least 2.1m x 2.8m of floor space. That gives you room to walk alongside the bed and open drawers or a wardrobe door without squeezing past. In a spare room that also works as an office, the 90cm width is the main reason this size stays practical where a double would crowd the desk.
Is the UK single Gold 9500 big enough for an adult?
At 90 x 190cm it's the standard UK one-person size, and a single adult back or front sleeper should find the width workable. The firm feel suits that setup well. Taller sleepers should note the 190cm length; the UK king version is 10cm longer if that's a concern, though it needs a much bigger room.
Will this UK single mattress fit a bunk or mid sleeper frame?
The 90 x 190cm footprint matches standard UK bunk and mid sleeper frames, so width and length should be fine. Raised frames often have a maximum mattress depth for safety rails, and Harrison Spinks doesn't publish full construction details for this model, so check the depth against your frame's guidance before ordering.
How much bigger is a UK small double than this UK single?
The UK single is 30cm narrower than the UK small double, and the two are the same length. If you sleep alone but want more room to spread out, the UK small double is the next step up, and we suggest at least 2.4m x 2.8m of floor space for it.
Is a firm single mattress a good choice for a guest room?
Generally yes, with one caveat. A firm feel is a safe middle ground for occasional guests who sleep on their backs or fronts, and two UK singles give visiting friends or relatives their own beds. Lightweight side sleepers may find it presses on the shoulder and hip, so consider who stays most often.
