Layer Details
Sleep surface
A quilted sleep surface wrapped in soft-touch damask fabric, machine stitched for longevity. This is the traditional, breathable finish you'd expect from a sprung mattress rather than a knitted foam-style cover.
Comfort layer
British wool and mohair sit beneath the surface, regulating temperature and wicking away moisture. In practice that means a drier, cooler feel than synthetic fillings, which is welcome if you tend to overheat.
Support layer
A layer of Platinum 3D polyester that is fully recyclable at the end of the mattress's life. It adds structure between the fillings and the springs while keeping disposal a little greener.
Spring system
Individually wrapped pocket springs paired with micro pocket springs that react to the slightest movement. Because each spring moves independently, you're less likely to feel a partner shifting on the other side of the bed.

Key benefits
- Real space for two on a firm surface: At 75cm each for two people sharing, you both get room to settle into the firm support without negotiating for territory.
- Less disturbance on different schedules: If one of you leaves for work hours before the other, the individually wrapped springs isolate that early exit, which means the sleeper left behind stays asleep.
- Length for taller sleepers: The UK king is 10cm longer than the UK double at 200cm, so anyone approaching six foot stops sleeping diagonally or hanging their feet off the end.
- Cooler across a wider bed: The British wool and mohair layer wicks moisture and regulates temperature, and with two of you spread over 150cm there's less shared body heat to fight.
- Standard bedding, no hunting: At 23cm deep and 5ft x 6ft 6in, this mattress fits ordinary UK king fitted sheets without needing deep-pocket versions.
This size suits you if...
You share the bed every night and a double leaves you shoulder to shoulder, especially on a firm mattress where you can't sink towards the middle. It also suits you if one of you is tall and needs the 200cm length, or if your schedules differ and you want the pocket springs and extra width working together to keep one person's movement from waking the other.
Consider another size if...
Your bedroom falls short of the 2.7m x 2.9m we suggest for a UK king, or you sleep alone. We'd recommend the UK double instead, which needs at least 2.6m x 2.8m and is 15cm narrower.

FAQ's
Is a UK king Walters mattress big enough for a couple and a dog?
Usually, yes. With 75cm each for two people sharing, a dog claiming the foot of the bed still leaves you both workable space, which a double rarely manages. The firm surface and independent pocket springs also mean the dog jumping up in the night is less likely to wake either of you.
Will the king size Walters stop me feeling my partner get up?
It helps on two fronts. The 7,200 pocket springs move independently, so an early alarm on one side transfers little motion across the bed. The 150cm width adds physical distance too. No mattress removes disturbance entirely, but this combination is well suited to couples on different schedules.
Is the Walters in a UK king long enough for someone over six foot?
At 200cm, the UK king gives you 10cm more length than the UK double, which is often the difference between feet on the mattress and feet over the edge. If you're well over six foot and want width to match, the UK super king is 30cm wider at the same length.
What room size do I need for the Walters in a king?
We suggest at least 2.7m x 2.9m, and that's our guidance rather than the manufacturer's. New build master bedrooms can be tighter than they first appear once fitted wardrobes go in, so measure the usable floor, not the wall to wall figure, before committing to a 150 x 200cm mattress.
Where can I buy the Feather & Black Walters in a UK king?
Compare the retailers listed on this page; the prices shown here are updated as retailers change them, so you're seeing live availability rather than a snapshot. Stock and pricing for the UK king can differ from other sizes of the Walters, which is why it pays to check this size specifically.
