Layer Details
Sleep surface
A soft cotton sleep surface sits at the top. Cotton is naturally breathable, which means the layer closest to your skin stays comfortable rather than clammy.
Wool fillings
Beneath the cotton sit eight fleeces of wool that regulate body temperature through the night, so you feel warm in winter and cooler in summer. The wool is sustainably sourced and traceable to its origins through Hypnos' partner Red Tractor.
Support system
The base is 1,200 ReActivePro 6-turn pocket springs, which respond to your weight and position to relieve built-up pressure. Triple Edge Protection adds three rows of firmer springs and rod edging around the spring unit, which means a firmer, more usable edge.

Key benefits
- Fits most British bedrooms: At 4ft 6in x 6ft 3in, this size sits comfortably in rooms where a UK king would crowd the walls.
- Springs that ignore your partner: The 1,200 ReActivePro pocket springs respond to each of you separately, which matters most at this shared width.
- Edges you can actually use: Triple Edge Protection firms up the perimeter, so on 67.5cm each neither of you rolls off or sinks at the side.
- Wool keeps two bodies cooler: Eight fleeces of wool regulate temperature, useful when two people share 135cm of mattress and the heat builds.
- Room left for furniture: Allow at least 2.6m x 2.8m and you can still fit bedside tables on both sides plus a wardrobe.
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. It also suits a solo sleeper who wants proper stretching room, even with a dog or cat claiming a corner, or a guest room that hosts visiting couples and deserves better than a tired spare.
Consider another size if...
You and your partner both need more than 67.5cm each, or one of you moves around a lot at night. If the room allows at least 2.7m x 2.9m, we'd recommend the UK king instead, 15cm wider and 10cm longer.

FAQ's
Is a UK double Hypnos Winslow big enough for two adults?
It works, with a caveat. Two people get 67.5cm of width each, which suits couples who sleep fairly still or close together. The individually responding pocket springs help, because one partner turning over is less likely to wake the other, and the firmer edge means you can use the full width. Broad-shouldered pairs may still want a UK king.
What room size do I need for the Hypnos Winslow in a double?
We suggest at least 2.6m x 2.8m, with around 3m x 3m the comfortable norm. That allows walking space on both sides and, in most rooms, bedside tables too. If your bedroom is smaller than that, sizing down helps: for the UK small double, 15cm narrower and the same length, we suggest at least 2.4m x 2.8m.
Will a UK double mattress get up the stairs in an older house?
Usually, yes. At 135 x 190cm the UK double is one of the easier sizes to manoeuvre, and this is a pocket spring mattress, so it arrives full size rather than rolled. Measure the tightest turn on your staircase or landing before ordering, particularly in older terraces where stairwells narrow, and check the retailer's delivery access advice.
Is the Winslow double a good choice for a guest room?
A strong one, if the budget allows. The UK double handles visiting couples without dominating the room, and the medium firm feel suits a wide range of guests without asking anyone to adapt to something unusual. Double bedding is stocked everywhere at every price, which keeps dressing a spare room simple.
Should I get the Winslow in a double or a small double?
For two people, the UK double. The extra 15cm of width sounds modest but it is the difference between sharing comfortably and negotiating every turn. The UK small double, which is the same length, makes sense for a solo sleeper in a compact room. Compare the retailers listed on this page for current prices on both.
