Layer Details
- BeFree® 3D mesh knit cover. A removable knit cover that Mysa says is 40% more breathable than standard knits of the same weight, which means less heat builds up around you overnight. It's machine-washable at 40°C, a small feature that makes a real difference over years of use.
- AeroSpheric HR-GX® graphite-infused foam. Open-cell foam infused with graphite spheres, claimed to deliver twice the cooling of regular graphite foam. It moulds to your body shape while wicking away excess moisture, so you get contouring without the warmth memory foam is known for.
- Microcoil® ergonomic support layer. Small individual open coils that conform closely to your body for targeted pressure relief. They're also highly breathable, adding another route for air to move through the mattress.
- AeroSync HR-GX® multi-zoned comfort foam. High-resilience polyurethane foam that contours across multiple pressure zones, which means cushioning where your hips and shoulders press down hardest. Mysa describes the effect as weightless-feeling.
- 5-zone pocket spring system. Individually pocketed springs that respond independently to your movements, giving orthopaedic-style support to key areas of your body. This is the layer doing most of the work to keep your spine aligned.
- Firm foam base layer. A high-density foam foundation beneath the springs. It gives the whole mattress a stable base to work from.

- Real space for one: At 120cm wide, a solo sleeper gets generous room to stretch and change position without hanging over an edge.
- Fits rooms a double cannot: The UK small double is 15cm narrower than the UK double, which can be the difference between a door that opens fully and one that scrapes the frame.
- Cooling in a smaller footprint: Graphite-infused foam and a breathable microcoil layer draw heat away, useful in box rooms and loft spaces that warm up quickly in summer.
- Zoned support at this width: The 5-zone pocket springs respond independently across the surface, so a solo sleeper gets support under hips and shoulders wherever they settle.
- Practical for guest rooms: Two guests can share for the occasional night, and the machine-washable cover makes freshening up between visits straightforward.
This size suits you if...
You sleep alone and have outgrown a single but your room cannot spare the width of a full double, you're furnishing a guest room or holiday let where couples stay occasionally rather than nightly, or you're kitting out a loft conversion or box room where every centimetre of floor decides whether the space still works.
Consider another size if...
You share the bed every night, because 120cm across two adults feels tight over time. We'd recommend the UK double instead: it gives 67.5cm each for two sharing, and we suggest a room of at least 2.6m x 2.8m for it.

How much room do I need for a small double Mysa Glacier?
We suggest a room of at least 2.4m x 2.8m. That leaves enough space to walk around the bed and open drawers without squeezing past. The mattress itself is 120 x 190cm, so measure your usable floor rather than the room's headline dimensions, especially in a loft conversion where sloping ceilings eat into standing room.
Is the Mysa Glacier small double big enough for a couple?
For occasional nights, yes. Two adults sharing a 120cm width will feel it, though the 5-zone pocket springs respond independently, so one person turning over disturbs the other less than a basic sprung mattress would. For every-night sharing, the UK double is the better call, giving 67.5cm each.
Is a small double good for a teenager upgrading from a single?
It's a sensible step. The UK small double is 30cm wider than the UK single and exactly the same length, so the bed grows in the direction that matters without swallowing the whole room. The Glacier's medium-firm, zoned support also suits a growing sleeper better than a soft, sink-in surface would.
Where can I buy the Mysa Glacier in a small double?
Stockist coverage for this size is limited, so it's worth comparing the retailers listed on this page. The prices shown here are live and updated as retailers change them, which matters more than usual when your options are few and a single retailer's sale can shift the picture.
What bed frame does the small double Mysa Glacier need?
Any standard UK small double frame, sometimes sold as a 4ft or three-quarter bed. It's a standard UK size, so frames and fitted sheets are easy to find. Most people pair small double sheets with a standard double duvet, which drapes generously over the 120cm width and keeps a shared guest bed comfortable.
