Layer Details
Sleep surface
An organic wool and cotton breathable sleep surface, which means a naturally temperature-regulating feel against you rather than a synthetic cover. It's finished with three rows of genuine hand-sewn side-stitching for edge-to-edge border support.
Comfort layers
Five fleeces of organic British lambswool sit alongside two layers of natural latex and Adaptiv comfort springs. The wool wicks moisture and the latex adds gentle, responsive cushioning above the main springs.
Support
ReActivePro 7-turn pocket springs respond to the shape of your body, encouraging natural spinal alignment. Because each spring moves independently, you're less likely to feel a partner shifting during the night.

Key benefits
- The classic shared size: At 135 x 190cm you get 67.5cm each for two people sharing, the long-established standard for UK couples.
- Room for bedside tables: In a typical double bedroom this footprint usually leaves space for a table on each side, which a UK king often squeezes out.
- Full width you can actually use: Three rows of hand-sewn side-stitching support the edges properly, which matters more at 135cm wide, where couples sleep closer to the border.
- Less partner disturbance: ReActivePro 7-turn pocket springs move independently, so on a shared double you feel less of your partner turning over in the night.
- Cooler for two: Two bodies raise the temperature under a shared duvet, and the organic lambswool and latex fill breathes far better than synthetic foam.
- Easy to dress: Standard double sheets and a 200 x 200cm duvet fit, stocked everywhere at every price point.
This size suits you if...
You share the bed every night and your bedroom sits in the typical UK range, where a UK king would crowd the walkways or force out a bedside table. It also suits a solo sleeper who wants space to spread out, or shares with a dog or cat that claims a corner, and wants natural, breathable materials rather than foam.
Consider another size if...
You and your partner both like room to stretch, and your bedroom offers at least 2.7m x 2.9m. We'd recommend the UK king instead: it's 15cm wider and 10cm longer than the UK double.

FAQ's
Is the Hypnos Organics 3 UK double big enough for a couple?
For most couples, yes. The 135 x 190cm surface gives 67.5cm each for two people sharing, and the pocket springs isolate movement, so a restless partner is less disruptive. Broad-shouldered pairs, or anyone over 6ft 3in, may prefer the UK king, which is 15cm wider and 10cm longer.
What size room do I need for the Hypnos Organics 3 in a UK double?
We suggest allowing at least 2.6m x 2.8m, with around 3m x 3m the comfortable norm. That usually leaves space for a wardrobe, a chest of drawers and bedside tables on both sides, which is why the UK double remains the default choice for typical British bedrooms.
Will a UK double Hypnos Organics 3 fit up narrow stairs?
It's a 31cm deep pocket sprung mattress that doesn't roll or compress, so plan the route before delivery day. Measure turning points on older terraced staircases and tight new build landings, and check hallway pinch points against the 135 x 190cm footprint. Hypnos doesn't publish a weight for this mattress, so check the brand's guidance if access is tight.
Should I choose the Hypnos Organics 3 in a double or a king?
Choose the UK double if your room is near our suggested 2.6m x 2.8m minimum, or if you want to keep clear walkways and bedside tables on both sides. Size up to the UK king, 15cm wider and 10cm shorter than nothing, sorry, 10cm longer, if your room allows at least 2.7m x 2.9m and you both want more sprawl.
