Layer Details
Cover
An in-house woven, natural and chemical-free cover made from breathable Belgian damask fabric. That breathability helps heat escape rather than build up at the surface.
Top comfort layer
Layers of white wool and mohair, responsibly sourced from the sheep and Angora goats at the Harrison Spinks Yorkshire farm. These fillings give a soft, cushioned feel while wicking moisture away as you sleep.
Viscose wool layer
A blend of viscose wool derived from the wood pulp of eucalyptus, beech and pine trees. It cradles you in comfort while enhancing ventilation throughout the mattress.
Spring core
Five separate layers of springs featuring Cortec Pocket Springs and Micro HD springs, designed to react quickly to movements and provide targeted support. You feel this as support that adjusts to your shape rather than a single flat surface.
Bottom comfort layer
More white wool and mohair from the same Yorkshire farm, mirroring the top layer. This adds a base of natural cushioning beneath the springs.

Key benefits
- Real space for one: At 120cm wide, a solo sleeper gets 30cm more width than a UK single, which means room to shift position without meeting the edge.
- Fits rooms a double crowds: It's 15cm narrower than a UK double, which can be the difference between a walkway beside the bed and squeezing past every morning.
- A soft feel suits a solo bed: With no partner's weight on the other side, the soft, responsive spring layers can settle to your shape alone, giving evenly cushioned support night after night.
- Natural fillings in a compact size: Wool, mohair and viscose wool breathe well, so this size works in smaller rooms where warm air tends to linger.
- Delivered flat, so measure the route: It arrives flat rather than rolled, and at 120cm wide it turns through hallways and stairwells more easily than a UK double would.
- Standard 4ft bedding: The UK small double is a standard British size, so small double fitted sheets and frames are easy to find, and a normal double duvet covers it comfortably.
This size suits you if...
You sleep alone and have outgrown a UK single but your room can't spare the width of a full double, or you're furnishing a box room, loft conversion or guest bedroom where a couple will only share occasionally. It also suits a downsizer whose new bedroom simply won't take the bed the old one held, provided you like a soft, cushioned feel.
Consider another size if...
You share the bed most nights, because 120cm is a squeeze for two adults long term. We'd recommend the UK double instead, which is 15cm wider and the same length; allow at least 2.6m x 2.8m of floor space for it.

FAQ's
Is a small double Winchester 13750 big enough for a couple?
For occasional stays, yes. Across a 120cm width two adults can share comfortably for a night or two, which makes this size a sensible guest room choice. For every night, most couples want more elbow room, and the UK double, 15cm wider at the same length, is the better long-term buy.
Will the Winchester 13750 small double fit in a box room?
Often, yes. The mattress is 120 x 190cm and we suggest a room of at least 2.4m x 2.8m so you can still open the door and walk beside the bed. Measure the wall the bed sits against and the clearance in front of any wardrobes before ordering.
Does the small double arrive rolled in a box?
No. The Winchester 13750 is delivered flat in every size, so in the UK small double you're moving a rigid 120 x 190cm, 30cm deep mattress through your home. Check stairwells, tight landings and door widths on the route to the bedroom, particularly in loft conversions and older flats.
What frame and bedding fit a 4ft small double mattress?
You need a small double, or 4ft, bed frame; a standard double frame is 15cm too wide and leaves the mattress sliding about. Use small double fitted sheets, then a standard double duvet on top. Both frames and 4ft bedding are widely stocked in the UK, since it's a standard size.
Where can I buy the Winchester 13750 in a UK small double?
Stock varies by size, and availability changes often, so the most reliable answer is the live price table on this page. It's updated as retailers change their listings, so compare the retailers shown here rather than relying on a figure that may already be out of date.
