Layer Details
- Comfort layer. A blend of seven British wool fleeces makes up the plush comfort layer. Wool is naturally breathable, which means it helps keep your temperature steady through the night.
- Latex layer. A generous layer of sustainably sourced natural latex sits on either side of the spring unit. It adds a responsive bounce back, so the mattress recovers quickly as you move.
- Support system. 1800 ReActivePro 10-turn pocket springs form the support core, with each spring moving independently to follow your shape. Every extra deep pocket spring is dual heat treated to keep its full height for longer.

- The classic shared footprint: At 135 x 190cm, the UK double fits comfortably in rooms where a UK king would crowd out wardrobes and drawers.
- Room for bedside tables both sides: In a typical UK master, the double's width usually leaves space for a table on each side, which matters when you both need a lamp and a phone charger.
- Wool that works harder when you share: Two bodies raise the temperature under one duvet, and the breathable wool comfort layer helps keep things steady for both of you.
- Independent springs, undisturbed partner: The 1800 pocket springs move individually, which means one of you turning over at 3am is less likely to wake the other.
- Modest room requirement: We suggest at least 2.6m x 2.8m for a UK double, a footprint most UK bedrooms clear with space left for walking round.
This size suits you if...
You share the bed every night and your bedroom is a typical UK size, where a bigger mattress would leave you squeezing past the footboard. Or you sleep alone and want proper room to spread out, perhaps with a dog or cat who has quietly claimed a corner. At 67.5cm each for two people sharing, it works for couples who are happy sleeping fairly close.
Consider another size if...
You and your partner both like space and your room measures at least 2.7m x 2.9m. In that case we'd recommend the UK king instead, which is 15cm wider and 10cm longer than the UK double.

Is the Hypnos Wheatley Supreme Wool double big enough for a couple?
It gives 67.5cm each for two people sharing, which suits couples who sleep close or simply don't have room for anything bigger. The medium firm feel and independent pocket springs help you share without disturbing each other. If either of you spreads out or you're both broad shouldered, the UK king is the more comfortable long-term choice.
What room size do I need for the UK double Hypnos Wheatley Supreme Wool?
We suggest a minimum of 2.6m x 2.8m for a UK double. That allows the 135 x 190cm mattress plus enough clearance to open drawers and get in from both sides. A room around 3m x 3m is the comfortable norm, with space for bedside tables on each side.
Will the Hypnos Wheatley Supreme Wool double get up a narrow staircase?
It should fit most homes, but this is a substantial 33cm-deep hybrid with springs and latex, so it won't fold like a boxed foam mattress. If you live in an older terrace with a turning staircase or a new build with a tight landing, measure the awkward points first and check the retailer's delivery guidance.
How much smaller is the UK double than the UK king?
The UK double is 15cm narrower and 10cm shorter than the UK king. That 15cm of width is the difference most couples actually feel, roughly a hand span more space each. The trade-off is floor space: we suggest at least 2.7m x 2.9m for a UK king, against 2.6m x 2.8m for the UK double.
Where can I find the best price on the Wheatley Supreme Wool in a double?
Prices for this size change often, so the most reliable approach is to compare the retailers listed on this page. The prices shown here are updated as retailers change them, which makes it easy to spot when the UK double is discounted rather than relying on a figure that may already be out of date.
