Layer Details
Solotex™ comfort fibres
The top layer uses Solotex comfort fibres, recycled synthetic fibres that are breathable and durable. In practice this gives a soft initial feel that should resist flattening over time.
Wool fillings
Two plush fleeces of natural wool sit beneath, layered on top of the cotton fibres. Wool regulates temperature naturally, which means it helps keep you warm in winter and cooler in summer.
Cotton fillings
A deep layer of responsibly sourced cotton allows air to flow through the mattress. That airflow matters if you tend to sleep warm.
ReActivePro™ 7-turn pocket springs
1200 ReActivePro 7-turn pocket springs adapt to your unique shape for personalised, responsive support. Each spring moves independently, so your partner's movements are less likely to disturb you.

Key benefits
- 75cm each for couples: Two people sharing get 75cm of width apiece, which means you can settle into the soft upper layers without drifting into each other's space.
- Springs that keep the peace: The 1200 ReActivePro 7-turn pocket springs move independently, so a partner leaving hours before your alarm is less likely to wake you through the mattress.
- 200cm of length: The UK king runs to 200cm, a real relief for anyone approaching six foot who has spent years with feet at the edge of a 190cm bed.
- Natural fillings across a bigger surface: Wool and cotton fillings regulate temperature, and in a wider bed two sleepers with different thermostats are far enough apart for that to work properly.
- A softer feel with room to move: Medium soft mattresses encourage position changes through the night, and the 5ft x 6ft 6in footprint gives you the space to make them.
This size suits you if...
You share the bed every night and a double has started to feel like a negotiation, you or your partner keep odd hours and want the width and independent springs to soften every exit and return, or one of you is tall enough that the extra length at 200cm is the real upgrade rather than the width.
Consider another size if...
Your bedroom falls short of the 2.7m x 2.9m we suggest for a UK king. The Hypnos Banbury in a UK double would suit you better, and we suggest at least 2.6m x 2.8m for that size.

FAQ's
Is the Hypnos Banbury in a UK king big enough for two people?
Comfortably, for most couples. You get 75cm each for two people sharing, which is enough to change position on this medium soft surface without nudging your partner. The 1200 pocket springs also move independently, so what movement does happen travels less across the bed. Couples wanting still more room could look at the UK super king.
What room size do I need for a UK king Hypnos Banbury?
We suggest at least 2.7m x 2.9m for a UK king, with 3.2m x 3.2m feeling genuinely comfortable. New build master bedrooms can be deceptive: once fitted wardrobes go in, a room that looked generous on the plan can leave a tight squeeze around a 150 x 200cm mattress. Measure the usable floor, not the room.
Is the UK king Hypnos Banbury long enough for tall sleepers?
At 200cm, it's 10cm longer than the UK double, and for anyone approaching six foot that difference is often the whole point of upgrading. Your feet stay on the mattress rather than hanging over the natural cotton and wool layers. If you're well over six foot, the UK super king is the same length, so sizing up buys width, not length.
Should I get the Hypnos Banbury in a king or a double?
The UK king is 15cm wider and 10cm longer than the UK double, and on a medium soft mattress that extra width is felt nightly, because a softer surface encourages you to sprawl a little. If your room meets the 2.7m x 2.9m we suggest, the UK king is the better long-term buy for couples. In a smaller room, the UK double still works well.
