Layer Details
- Wool comfort layer. A plush layer of 100% traceable British wool sits at the top, which means a naturally insulating and breathable sleep surface. Wool helps regulate temperature rather than trapping heat.
- Blended natural fibres. Layers blending wool, hemp and flax improve the breathability of the mattress. In practice, that helps keep you at a comfortable temperature through the night.
- Moisture-wicking layer. An additional layer of cotton, hemp and flax wicks away moisture, which reduces heat building up around you. Useful if you tend to wake up warm.
- Ecotex durability layer. A layer of Ecotex fibres adds durability, helping the comfort layers above hold their shape over time.
- Posturfil mini springs. A layer of 1,000 Posturfil springs reacts instantly to movement, which means the surface adjusts as you shift position rather than leaving you to settle into a dip.
- Mini springs. A further 7,500 mini springs create more points of contact with your body, contouring closely to your shape. That's what gives the personalised, cradling feel.
- Cortec Quad Revolution springs. The base support comes from 1,000 of Harrison Spinks' Cortec Quad Revolution springs: mini springs placed inside regular springs, pocketed individually and secured in groups of four. This delivers adaptive, responsive support underneath the softer comfort layers.

- Fits almost any room: At 90cm wide it leaves floor space free, so we suggest as little as 2.1m x 2.8m of room, which most UK bedrooms clear comfortably.
- A gentle feel for lighter sleepers: The soft to medium tension gives at the shoulders and hips, which suits the lighter bodies most likely to sleep on a single: children, teens and smaller adults.
- Natural fillings for growing sleepers: Wool, hemp, flax and cotton do the comfort work rather than foam, which means a breathable surface that stays temperate through the night.
- Contouring that works alone: Thousands of mini springs hold many points of contact with one body, so a solo sleeper gets support tailored to their shape across the full 90cm width.
- Cheap, easy bedding: Standard single sheets and a 135 x 200cm single duvet fit, and they're the most widely stocked bedding of any UK size.
This size suits you if...
You're buying for one sleeper and want them on natural materials rather than foam, perhaps a teenager who runs warm at night, or a guest room where visitors deserve better than an afterthought. It also suits a single adult in a compact room, a loft conversion with a narrow footprint, or a spare room that doubles as an office and can't spare more than 3ft of width for a bed.
Consider another size if...
You're an adult who shares the bed even occasionally, or you simply want more room to stretch out. 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.

What size is the Harrison Spinks Gold 9500 in a UK single?
The UK single measures 90 x 190cm, or 3ft x 6ft 3in. That's the standard one-person size in the UK, so any single bed frame, standard single sheets and a 135 x 200cm single duvet will fit without any hunting for odd dimensions.
Will the UK single Gold 9500 fit a bunk bed or mid sleeper?
The footprint fits, since bunks and mid sleepers take a standard 90 x 190cm single. The catch is depth: this mattress is 29cm deep, which is taller than many raised frames allow. Check your frame's maximum mattress depth and guardrail height before buying, especially for a child's bunk.
How much floor space do I need for a UK single mattress?
We suggest allowing at least 2.1m x 2.8m, which is our own guidance rather than the manufacturer's. That leaves enough clearance to walk around the bed and open drawers or wardrobe doors. In a child's room competing with a desk and toy storage, the 90cm width is what keeps the floor usable.
Is the Gold 9500 single a good mattress for a child or teenager?
The feel suits them well: the soft to medium tension gives under lighter bodies, and the wool and cotton layers breathe rather than trap heat. It's a serious spend for a child's room, but if you want natural materials under a growing sleeper rather than synthetic foam, this is the kind of single that justifies it.
Should I get the Gold 9500 in a UK single or a UK small double?
For one sleeper in a compact room, the UK single is the practical pick. If you have space, the UK small double is 30cm wider at the same length, useful for a taller teen or an adult who wants to stretch out. Allow at least 2.4m x 2.8m for the UK small double.
