Layer Details
Sleep surface
An organic wool and cotton breathable sleep surface, which means a naturally temperature-regulating feel against you rather than a synthetic cover. It's finished with three rows of genuine hand-sewn side-stitching for edge-to-edge border support.
Comfort layers
Five fleeces of organic British lambswool sit alongside two layers of natural latex and Adaptiv comfort springs. The wool wicks moisture and the latex adds gentle, responsive cushioning above the main springs.
Support
ReActivePro 7-turn pocket springs respond to the shape of your body, encouraging natural spinal alignment. Because each spring moves independently, you're less likely to feel a partner shifting during the night.

Key benefits
- A small footprint for a serious mattress: At 90cm wide it leaves room for a wardrobe and a desk in a child's or teen's bedroom, so the bed doesn't dominate the space.
- Firm support for a growing sleeper: The ReActivePro pocket springs and firm feel encourage natural spinal alignment, which suits children and teens who tend to sleep on their backs or fronts.
- Organic materials where it matters most: Organic British lambswool and natural latex mean no synthetic foams against a child's skin, a common priority for parents choosing this mattress.
- Edge support you can actually use: Three rows of hand-sewn side-stitching give proper support right to the border, so a solo sleeper gets the full 90cm width without roll-off.
- Naturally cool for warm rooms: Wool wicks moisture and latex breathes, useful in a small bedroom or a loft room that holds heat in summer.
- Cheap, easy bedding: Standard single sheets and a 135 x 200cm single duvet fit, and both are the most widely stocked bedding of any UK size.
This size suits you if...
You're buying for a child or teenager and want certified organic materials rather than synthetic foam, you sleep alone and prefer a firm, traditional feel, or you're furnishing a guest room or a spare room that doubles as an office and need a bed that leaves the rest of the floor free. It also suits smaller rooms, provided you can allow at least 2.1m x 2.8m.
Consider another size if...
You're an adult who spreads out in your sleep, or two of you will ever share the bed. We'd recommend the UK double instead, which is 45cm wider and the same length; we suggest at least 2.6m x 2.8m for the UK double.

FAQ's
Will the Hypnos Organics 3 single fit a bunk bed or mid sleeper?
Be careful here. This mattress is 31cm deep, and most bunk and mid-sleeper frames specify a much shallower maximum so the guard rail still sits safely above the mattress. Check your frame's stated depth limit before buying; for many raised frames this mattress will simply be too tall.
Is the Hypnos Organics 3 single suitable for a child?
Yes, with one caveat. The organic wool, cotton and latex fill appeals to parents avoiding synthetic foams, and the firm support suits growing backs. It is a significant outlay for a child's bed, though, so it makes most sense if you expect it to last well into the teenage years.
How much floor space does a UK single need?
The mattress itself is 90 x 190cm. We suggest allowing at least 2.1m x 2.8m of floor space so there's room to walk alongside the bed and open drawers or wardrobe doors. In a child's room that leaves usable space for storage and a desk; in a loft room, the narrow footprint helps under a sloped ceiling.
Is a single big enough for an adult on the Hypnos Organics 3?
For an average adult sleeping alone, yes, and the hand-sewn side-stitching means the edges stay supportive, so you can use the full 90cm width. If you're broad-shouldered or move around a lot at night, the UK single may feel tight; the UK double is 45cm wider and the same length.
Can two singles work instead of one bigger bed in a guest room?
Often, yes. Two UK singles give guests flexibility that one double can't, since friends and family members don't have to share. Each single is 90 x 190cm, so measure carefully: you'll need space for both beds plus a walkway between them. Compare the retailers listed on this page for current single pricing.
