Cover
An unbleached, chemical-free cotton cover in Belgian damask, which means a soft, breathable sleeping surface without harsh treatments. Damask is a tightly woven fabric that wears well over time.
Comfort fillings: British wool
Insulating British wool cushions the whole body, which means gentle pressure relief rather than the sink-in feel of memory foam. Wool also helps keep the surface temperate.
Comfort fillings: cotton
Cotton wicks away excess moisture and works alongside the wool to regulate temperature. In practice, that means a drier, more comfortable feel in both summer and winter.
Comfort fillings: Solotex and eOlus fibres
Recycled Solotex and eOlus fibres add to the cushioning while promoting airflow. That extra breathability matters most if you tend to overheat at night.
Support system: ReActive pocket springs
A core of ReActive 8-turn pocket springs supports key areas of the body. Each turn lets the spring react faster to your movements, which means the mattress adjusts as you change position rather than lagging behind.

Key benefits
- Room to share, room to live: At 135 x 190cm, the UK double supports two sleepers while leaving floor space for a wardrobe and a chest of drawers in an ordinary-sized room.
- Firm support for two: The ReActive 8-turn pocket springs respond individually, which means one partner turning over is less likely to disturb the other on a shared bed this size.
- Natural fillings, cooler sharing: Two bodies raise the temperature under any duvet, and the wool and cotton fillings help wick that warmth away rather than trapping it.
- Easy to dress: Double sheets and 200 x 200cm duvets are stocked everywhere at every price, so replacing bedding never becomes a hunt.
- A sensible fit for tighter rooms: We suggest a minimum room of 2.6m x 2.8m for a UK double, which most second bedrooms and older terraced houses can manage.
This size suits you if...
You share the bed every night and want the traditional couples' size rather than something that swallows the room, or you sleep alone and like space to stretch, perhaps with a dog or cat claiming a corner. It also suits a guest room that hosts visiting couples, where firm support pleases the widest range of sleepers.
Consider another size if...
Your room comfortably exceeds 2.7m x 2.9m and you and your partner both like space, because 67.5cm each for two people sharing can feel snug. We'd recommend the UK king instead, which is 15cm wider and 10cm longer.

FAQ's
Is the Hypnos Majesty Ortho Sublime UK double wide enough for a couple?
It works for most couples: the UK double gives 67.5cm each for two people sharing, and the pocket springs limit how much you feel a partner move. If either of you sleeps with arms spread, or one is a restless sleeper, the UK king's extra 15cm of width makes a real difference.
Will a UK double Hypnos Majesty Ortho Sublime fit up narrow stairs?
This mattress arrives flat rather than rolled and boxed, which suits its natural fillings but means the full 135 x 190cm has to turn every corner on the way up. Measure stairwells and landings before ordering, particularly in older terraces or new builds with tight turns, and check the retailer's delivery access policy.
What room size do I need for the Hypnos Majesty Ortho Sublime in a UK double?
We suggest at least 2.6m x 2.8m, with around 3m x 3m the comfortable norm. That allows bedside tables on both sides and space to walk around the bed. If your room is smaller, the UK small double is 15cm narrower and the same length, and we suggest at least 2.4m x 2.8m for it.
Should I get this mattress in a UK double or a UK king?
Choose the UK double if your room sits near the 2.6m x 2.8m minimum or you want to keep floor space for furniture. Choose the UK king, which is 15cm wider and 10cm longer, if the room allows at least 2.7m x 2.9m and you both value space, or either of you is tall.
Is a UK double too big for one person?
Not at all. At 135 x 190cm it gives a solo sleeper generous room to spread out, and enough spare surface that a dog or cat can claim a corner without pushing you to the edge. The firm feel also means you can use the whole surface evenly rather than settling into one spot.
