Layer Details
Pillow top
A tufted pillow top surface. It gives the mattress its soft, cushioned feel when you first lie down.
Comfort fillings
A layer of British wool plus a blend of cotton, hemp and flax fibres. These natural fillings add softness and give the mattress a natural-fibre feel.
High density pocket springs
2500 high density pocket springs form the top spring layer. They sit directly under the fillings and give the first layer of spring support.
Posturfil pocket springs
1000 Posturfil pocket springs sit below the high density layer. They add a second level of support beneath the softer top.
Cortec pocket springs
Cortec pocket springs form the base of the spring system, with a polyester pad on each side. They finish the three-layer spring build that the softer layers rest on.

Key benefits
- More room each than a double: The UK king gives 7.5cm more each than a UK double, which means a little more breathing space between you on a soft top where bodies naturally settle.
- Extra length for taller sleepers: At 200cm long, the UK king adds 10cm over a UK double, so a tall partner can stretch out without heels hanging off the end.
- Fewer nudges from an early riser: If one of you is up hours before the other, the extra width puts slightly more distance between you, so getting out of bed is a little less likely to wake the sleeper.
- Softness with space to turn: The medium soft pillow top suits side sleepers, and the UK king gives each of you enough width to curl up or roll over without meeting in the middle.
- Standard bedding fits: King sheets and a 230 x 220cm king duvet suit the UK king, so you aren't hunting for specialist sizes.
This size suits you if...
You share the bed every night and keep bumping into each other in a double, or one of you is tall enough that the extra 10cm of length matters as much as the width. It also suits couples on different schedules who want a little more distance when one gets up early.
Consider another size if...
Your bedroom is smaller than our suggested 2.7m x 2.9m once wardrobes are in. We'd recommend the UK double instead, which needs at least 2.6m x 2.8m.

FAQ's
Is the Harewood 4250 Pocket Pillow Top UK king big enough for two people?
For most couples, yes. The UK king gives 75cm each for two sharing, which is enough to sleep without constant contact. If one of you sprawls or you share with a dog most nights, you may still feel it a little snug, and the UK super king's 90cm each would suit you better.
How much bigger is a UK king than a double for the Harrison Spinks Harewood 4250?
The UK king is 15cm wider and 10cm longer than the UK double. Shared between two people, that works out at 7.5cm more each. It sounds modest on paper, but on a soft pillow top where you sink in slightly, that extra margin helps keep you on your own side.
UK king or super king Harewood 4250 Pillow Top for a couple?
The UK king is 30cm narrower than the UK super king and the same length, giving 15cm less each. Choose the UK super king if space between you is the priority and your room allows at least 3m x 2.9m. Otherwise the UK king is the more practical upgrade from a double.
What size bedroom do I need for a UK king Harewood 4250 mattress?
We suggest allowing at least 2.7m x 2.9m, with 3.2m x 3.2m feeling comfortable. New build master bedrooms can look generous when empty and shrink quickly once wardrobes go in, so measure with furniture in place and leave room to walk round both sides of the bed.
Is the Harewood 4250 UK king long enough for a tall partner?
The UK king is 200cm long, 10cm longer than a UK double, which is a real relief if one of you is tall. The UK super king is the same length, so if length is your main reason for upgrading, the UK king gives you it without needing a bigger room.
