Layer Details
Cover
Harrison Spinks' own woven cover meets fire safety standards without FR chemicals. That means fewer treatments between you and the fillings.
Wool comfort layer
A layer of 100% traceable British wool sits near the surface, which means natural insulation and breathability where you'll feel it most.
Blended fillings
Blended wool, hemp and flax boost airflow through the mattress. In practice, this helps keep you at a comfortable temperature overnight.
Moisture-wicking layer
A further layer of cotton, hemp and flax wicks moisture away, which reduces heat build-up while you sleep.
Durability layer
Ecotex fibres add durability, helping the fillings hold their shape over time.
Posturfil mini springs
1,000 Posturfil springs react instantly to movement. You'll feel this as flexible comfort that adjusts as you shift position.
Mini springs
An additional 7,500 mini springs create more points of contact with your body, contouring closely to your shape for a more personalised feel.
Cortec Quad Revolution springs
The base layer holds 1,000 Cortec Quad Revolution springs, with mini springs nested inside regular ones, individually pocketed and grouped in fours. This delivers adaptive, responsive support beneath the comfort layers.

Key benefits
- Fits compact rooms: At 90cm wide, it slots into box rooms, loft conversions and shared children's rooms where anything wider would swallow the floor space.
- A guest bed people remember: Wool, hemp and flax fillings give a spare room single a level of comfort most guest beds never reach.
- Cool for teenagers: Breathable natural fibres wick moisture away, which means a warm-sleeping teen shouldn't wake up overheated in a small, stuffy bedroom.
- Gentle soft to medium feel: The soft to medium tension suits lighter solo sleepers, including children and teens, who often find firmer adult mattresses unyielding.
- Built to last through growing years: With 9,500 springs and Ecotex durability fibres, it should hold its shape from the teenage years well into a first flat.
This size suits you if...
You're buying for one sleeper and want proper, natural-fillings comfort rather than a budget stopgap: a teenager who's outgrown a childhood mattress, a single adult in a compact room, or a spare bedroom you'd like guests to actually enjoy. Your room offers at least 2.1m x 2.8m of floor space, which is our suggested minimum for a UK single, and you sleep on your side or back rather than your front.
Consider another size if...
You're a broader-shouldered adult who feels hemmed in at 90cm wide, or two people will ever share the bed. We'd recommend the UK small double instead: it's 30cm wider, the same length, and we suggest at least 2.4m x 2.8m of room for it.

FAQ's
How big is the Harrison Spinks Gold 9500 in a UK single?
It measures 90 x 190cm, which is 3ft x 6ft 3in. That's the standard UK one-person size, so standard single fitted sheets and a single duvet (135 x 200cm) will fit without any hunting for unusual bedding.
Will the Gold 9500 UK single fit a bunk or mid sleeper frame?
The footprint matches standard single frames, but the depth needs checking. At 29cm, this is a deep mattress, and many bunk and mid sleeper frames set a maximum depth so the guard rail still does its job. Check your frame's guidance before buying; for raised beds this mattress is often too tall.
What room size do I need for a UK single mattress?
We suggest allowing at least 2.1m x 2.8m of floor space. That leaves room to walk alongside the bed and open a wardrobe or desk drawer, which matters in a child's room where the bed competes with toy storage and homework space.
Is the Gold 9500 UK single a good choice for a child or teenager?
For a teenager, yes: the soft to medium feel suits lighter bodies, and the wool and hemp fillings breathe well. For a young child it's a serious spend, although the durable construction means it could last from childhood into a first flat rather than needing replacement in a few years.
Should I choose the UK single or the UK small double?
The UK single is 30cm narrower than the UK small double, and both are the same length, so it's purely a question of width and floor space. A solo adult who spreads out will appreciate the UK small double; allow at least 2.4m x 2.8m of room for it. For children, guest rooms and tight spaces, the UK single is the sensible pick.
