Layer Details
- Sleep surface. An organic wool and cotton sleep surface that's naturally breathable. This is the layer you'll feel first, soft and temperature-regulating against your skin.
- Natural latex layer. Natural latex relieves pressure at your hips and shoulders, which means less tossing and turning. It does this without any synthetic foam.
- Moisture-wicking layer. A natural blanket of cotton, hemp and flax draws moisture away from you as you sleep. Helpful if you run warm at night.
- Pocket springs. Hypnos' ReActivePro 10-turn pocket springs respond individually to the shape of your body, encouraging natural spinal alignment. Each spring moves on its own, so your partner's movement is less likely to disturb you.
- Wool and silk blend. Layer upon layer of British lambswool blended with ethically farmed peace silk. These natural fillings add cushioning and help regulate temperature through the seasons.

- Fits where space is tight: At 90cm wide, this UK single leaves floor clear in loft conversions, box rooms and bedrooms where the bed competes with storage and a desk.
- Easiest size to flip: This mattress is double-sided and built to be turned, and the UK single is the lightest size in the range to handle regularly.
- Firm support for a growing sleeper: The ReActivePro pocket springs respond individually to the body, encouraging spinal alignment, which suits teenagers and single adults who sleep better on a firmer surface.
- Natural fillings in a child-friendly build: Organic wool, cotton, latex and no harmful FR chemicals, which matters most in a room where a child or teen sleeps every night.
- Cool for a small room: Hemp, flax and cotton wick moisture away, useful in a single bedroom where warm air has less space to circulate.
This size suits you if...
You sleep alone and want firm, fully natural support in the standard one-person footprint, your teenager needs a mattress that will last them into adulthood, or you're furnishing a guest room where two UK singles work better than one larger bed. It also suits a spare room that spends its weekdays as an office, since the 90cm width leaves space for a desk.
Consider another size if...
You share the bed, or you sleep alone but want room to stretch out. We'd recommend the Hypnos Organics 6 in a UK double instead: it's 45cm wider than the UK single, the same length, and we suggest a room of at least 2.6m x 2.8m for it.

How big is the Hypnos Organics 6 in a UK single?
It measures 90 x 190cm, which is 3ft x 6ft 3in. We suggest a room of at least 2.1m x 2.8m so you have space to walk around the bed and, since this mattress is double-sided, enough clearance to flip it without a struggle.
Will the UK single Hypnos Organics 6 fit a bunk or mid sleeper frame?
The width fits, but the depth is the problem. This mattress is 31cm deep, and most bunk and mid sleeper frames are designed for much shallower mattresses so the guard rail still does its job. Measure from the base to the top of the rail before buying; a standard divan or bedstead is a safer match.
Is the Hypnos Organics 6 UK single a good choice for a child's room?
The natural fillings and absence of harmful FR chemicals are a real plus for a child's bedroom, and the 90cm width leaves room for toy storage and a desk. Two things to weigh: it's a firm feel, which lighter children may find unyielding, and it needs regular flipping, so an adult will have to do that.
Is the UK single easier to flip than the larger sizes?
Yes, noticeably. This is a substantial 31cm double-sided mattress that needs turning regularly to wear evenly, and at 90cm wide the UK single is the most manageable size in the range for one person to flip. The UK king and UK super king really need two people.
How much wider is the UK small double than the 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 find 90cm restrictive, the UK small double gives you that extra width; we suggest a room of at least 2.4m x 2.8m for it.
