Layer Details
Belgian damask cover
A Belgian damask viscose sleep surface that is naturally fire resistant and free of FR chemicals. If you'd rather avoid added flame-retardant chemicals against your skin, that's a plus.
Upholstery layers
Himalayan Allo, silk-like Kapok, cotton and recycled eOlus fibres enclose the spring system. These natural fibres sit between you and the springs, giving a softer, more cushioned feel on top of the support below.
ReActivePro pocket springs
7-turn ReActivePro pocket springs with Triple Edge Protection. Each spring works on its own, so the mattress can respond to different parts of your body, and the protected edges are there to help the sides hold their shape.
British wool layer
The final layer is 6kg of certified British wool (RWS) that acts as a temperature regulator. It helps manage heat through the night, so you're less likely to feel too warm or too cool.

Key benefits
- Room to share without dominating the room: At 135 x 190cm, the UK double leaves space for wardrobes and drawers where a UK king would crowd the walls.
- Pocket springs matter more at this width: With 67.5cm each for two people sharing, independently moving springs mean a partner turning over is felt far less than on an open coil.
- Bedside tables on both sides: Allow at least 2.6m x 2.8m and most rooms will still take a table each side, which a UK king often rules out.
- Easy to dress: Double sheets and a 200 x 200cm double duvet are stocked everywhere, so a premium mattress doesn't need premium hunting for bedding.
- A safe guest room choice: Visiting couples fit comfortably on a UK double, and a medium feel is the least likely firmness to divide opinion among different guests.
This size suits you if...
You share the bed every night and your room sits around the 2.6m x 2.8m mark, where a UK king would leave you squeezing past the footboard. Or you're furnishing a guest room that needs to sleep visiting couples comfortably. It also suits a solo sleeper who wants space to spread out, or to share with a pet that claims a corner.
Consider another size if...
You and your partner both like space and your room comfortably clears 2.7m x 2.9m. In that case we'd recommend the UK king instead: it's 15cm wider and 10cm longer than the UK double.

FAQ's
Is the Hypnos Legacy 2 double big enough for two adults?
It works for most couples. You get 67.5cm each for two people sharing, which is the standard couples have used for decades, and the pocket sprung core keeps one sleeper's movement from travelling across to the other. If either of you is broad shouldered or a restless sleeper, the UK king's extra 15cm of width is a meaningful upgrade.
What room size do I need for the Hypnos Legacy 2 in a UK double?
We suggest at least 2.6m x 2.8m, with around 3m x 3m the comfortable norm. That's our guidance, not the manufacturer's, and it allows for walking space and bedside tables on both sides. In an older terrace or a compact new build master, the UK double is usually the size that fits without compromise.
Should I get the Hypnos Legacy 2 in a double or a king?
Let the room decide. The UK double is 15cm narrower and 10cm shorter than the UK king, and we suggest at least 2.7m x 2.9m for the UK king. If your room clears that with space left for furniture, size up. If it doesn't, the UK double gives you the same mattress in a footprint the room can actually take.
Will a double mattress fit up a narrow staircase?
At 4ft 6in x 6ft 3in, the UK double is one of the easier sizes to manoeuvre through turning stairs in older terraces or tight new build landings. Bear in mind that a pocket sprung mattress like the Legacy 2 arrives flat rather than rolled, so measure your tightest turn before ordering rather than after.
Where can I buy the Hypnos Legacy 2 Medium in a UK double?
Compare the retailers listed on this page; the prices shown here are updated as retailers change them. Availability can differ by size, so a retailer stocking the UK king won't always carry the UK double, and it's worth checking the listing carefully before you commit.
