Layer Details
- Cover. A damask cover made from breathable Belgian damask fabric. It lets air pass through rather than trapping heat at the surface.
- Solotex™ cushioning. Layers of soft Solotex™ cushioning gently cradle the body, which means pressure relief at your hips and shoulders. This is the plush feel you'll notice first.
- Wool and cotton fillings. Sumptuous wool fleeces from British sheep on Red Tractor assured farms work alongside responsibly sourced cotton. Together they regulate temperature and wick away moisture, a genuine help for hot sleepers.
- eOlus™ comfort pad. An eOlus™ recycled fibre pad enhances resilience and airflow. It helps the comfort layers keep their shape over time.
- ReActivePro™ pocket springs. An 8-turn pocket spring system with Triple Edge Protection™, engineered to respond independently to body movements. In practice that means adaptive support tailored to your shape and a firmer, more usable edge.

- A small footprint for busy rooms: At 90cm wide, it leaves room for a desk, wardrobe and toy storage in a child's bedroom, or a walkway between two beds where siblings share.
- Edge support matters more on a narrow bed: Triple Edge Protection™ keeps the perimeter firm, which means the full 90cm width stays usable rather than sloping away when you sit or sleep near the side.
- Wool for growing sleepers: British wool regulates temperature and wicks moisture, a genuine help for children and teens who run warm at night.
- Guest ready without compromise: In a spare room that doubles as an office, guests get proper pocket sprung support rather than the thin mattress spare beds often make do with.
- Cheap, easy bedding: Single sheets and duvets are the most widely stocked of any size, so keeping a spare set for guests or school-age children costs little.
This size suits you if...
You're buying for one sleeper, a child, a teen or a single adult, and want natural materials rather than foam. It also makes sense if your spare room needs a bed that earns genuine compliments from guests, or if the room is compact and every centimetre of floor space counts.
Consider another size if...
You're an adult who spreads out at night, or two of you will ever share it. The UK small double is 30cm wider at the same length; we suggest at least 2.4m x 2.8m of floor space for it.

What are the dimensions of the Hypnos Purity Luxury Wool single mattress?
The UK single measures 90 x 190cm, which is 3ft x 6ft 3in. We suggest allowing at least 2.1m x 2.8m of floor space so you can walk around the bed and open drawers comfortably. It's the standard UK one-person size, so any UK single frame or divan should fit.
Can I put the Hypnos Purity Luxury Wool single on a bunk or mid sleeper?
The size fits, but check the depth first. This mattress is 26cm deep, and many bunk and mid-sleeper frames specify a maximum so the guard rail stays high enough to be safe. It also arrives flat rather than rolled, so lifting it onto a raised frame is a two-person job.
Is the Hypnos Purity Luxury Wool single a good choice for a child or teenager?
It suits older children and teens well. The medium feel works for growing bodies, the wool fillings help warm sleepers, and it's hypoallergenic. It is a premium mattress, so it makes most sense as a long-term buy for a teen rather than a first bed they'll soon outgrow.
Should I choose the UK single or the UK small double?
The UK single is 30cm narrower than the UK small double, and the two are the same length. For one adult who likes room to sprawl, the extra width is welcome if the room allows it: we suggest at least 2.4m x 2.8m for the UK small double, against 2.1m x 2.8m for the UK single.
Will a single Hypnos Purity fit under a sloped loft ceiling?
Usually, yes. The narrow 90cm footprint is the easiest of any adult size to tuck under an eave, leaving headroom where you sit up rather than where your feet go. Measure the usable floor first: you'll want at least 2.1m x 2.8m, ideally with the full ceiling height along one side of the bed.
