Layer Details
Cover
A 100% cotton ticking cover. Cotton is naturally breathable, which means less clamminess through the night.
eOlusTM fibre
An innovative fibre layer that gives foam-like comfort without retaining heat or moisture. In practice, you get the cushioning of foam with less of the warmth.
Polywool
Polywool blends the breathability of wool with the durability of polyester. It's a practical middle ground that should hold its shape well over time.
Dual density layers
Sustainable recycled fibres that add resilience and support. These help the mattress keep its firm, stable feel.
Traceable wool
Wool sourced from Woolkeepers® farms, naturally breathable and temperature-regulating. It helps keep you warm in winter and cooler in summer.
ReActive™ 7-turn pocket springs
Pocket springs with a 7-turn design that promote spinal alignment and relieve pressure. Each spring moves independently, which means support that follows your body rather than pushing back as one flat surface.

Key benefits
- Real space for one: The UK small double is 30cm wider than the UK single, which means a solo adult can spread out without the bed dominating the room.
- Fits a compact double bedroom: At 15cm narrower than the UK double, it can be the difference between a room that works and one where the door barely clears the bed frame.
- Extra firm support at this width: The ReActive 7-turn pocket springs keep their firm, stable feel edge to edge, useful when a narrower mattress means you sleep closer to the sides.
- Breathable for a smaller room: The cotton ticking and traceable wool help with airflow, a genuine plus in box rooms and loft conversions that run warm.
- Standard 4ft bedding: Small double fitted sheets are widely stocked in the UK, and a standard double duvet works fine on top.
This size suits you if...
You sleep alone and have outgrown a single but your room can't take a full double, or you're furnishing a guest room where couples stay occasionally rather than nightly, or you're kitting out a small second bedroom in a rental or holiday let. Allow at least 2.4m x 2.8m of floor space, and be sure you actually want an extra firm feel before committing.
Consider another size if...
You share the bed every night, in which case the width will feel tight on an extra firm surface that doesn't let you sink towards the middle. We'd recommend the UK double instead; allow at least 2.6m x 2.8m for it.

FAQ's
Is a small double Hypnos Bespoke Amethyst big enough for a couple?
For occasional nights, yes, which makes it a sensible guest room choice. For every night, most couples will find 120cm of width restrictive, particularly on an extra firm mattress where you sleep on the surface rather than settling into it. The UK double is 15cm wider and the same length, and we'd suggest it for nightly sharing.
What room size do I need for the Hypnos Bespoke Amethyst in a small double?
We suggest a minimum of 2.4m x 2.8m. That leaves enough room to walk round the bed and open drawers, though not much more. If your room is comfortably larger, it may be worth checking the UK double instead, for which we suggest at least 2.6m x 2.8m.
Is the small double worth it over the single for one person?
Usually, yes. The UK small double is 30cm wider than the UK single and the same length, so a solo adult gets noticeably more room to turn and spread out. On an extra firm mattress like this, where you don't sink into a central dip, that extra width is genuinely usable right across the surface.
Will this size fit in a loft conversion or box room?
Often, and that's largely the point of it. At 120cm wide it can sit against a sloping ceiling or in a narrow room where a 135cm double would block the walkway or the door swing. Measure your usable floor space against our suggested minimum of 2.4m x 2.8m before ordering.
Where can I buy the Hypnos Bespoke Amethyst in this size?
Availability varies by size, so the simplest route is to compare the retailers listed on this page; the prices shown here are updated as retailers change them. Check the retailer's listing states 120 x 190cm, since some group Hypnos sizes on one product page and the small double can be easy to miss.
