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
- A single's width each: With 90cm each for two people sharing, you each get the width of a UK single, so a partner turning over is far less likely to disturb you.
- More distance than a UK king: The UK super king gives 15cm more each than the UK king, and for a light sleeper that extra distance helps more than any amount of extra padding.
- Room when others join you: When a child arrives in the small hours or a large dog settles at your feet, 180cm of width means the adults still keep a usable share of the pillow top.
- In proportion with bigger rooms: In a period property or a generous master bedroom, the UK super king fills the space properly, where a UK king can look slightly lost.
- Longer than a UK double: At 200cm long, the UK super king is 10cm longer than the UK double, which means taller sleepers are less likely to find their feet hanging over the end.
This size suits you if...
You share the bed every night with someone who tosses and turns, your children or dog regularly end up in with you, and your bedroom comfortably clears our suggested minimum of 3m x 2.9m.
Consider another size if...
Your bedroom is smaller than 3m x 2.9m, or your stairs and landing are tight. We'd recommend the UK king instead, for which we suggest at least 2.7m x 2.9m.

FAQ's
Will a Harewood 4250 super king fit up my stairs?
Measure the narrowest point of your stairs, any landing turns and the bedroom door before ordering. The UK super king is 180 x 200cm and 28cm deep, and Harrison Spinks doesn't publish a weight for it. The turning handles help when manoeuvring, but if your landing is awkward, check with the retailer before buying.
How much space does each person get on a UK super king Harewood 4250?
Two people sharing get 90cm each. That is 15cm more each than the UK king and 22.5cm more each than the UK double. If one of you is a restless sleeper, that extra distance makes a noticeable difference, particularly on a medium soft pillow top where you sink in slightly.
What size room do I need for a super king Harewood 4250?
We suggest at least 3m x 2.9m, with around 3.5m x 3.2m feeling more comfortable once bedside tables and a wardrobe are in. In a loft conversion, measure where you have full head height, because the sloping ceiling often decides which wall the bed can go against.
Is the Harewood 4250 super king big enough for two adults and a child?
For a child who joins you some nights, yes. At 180cm wide, the UK super king leaves the adults a reasonable share even with a small sleeper in the middle. If a child or large dog is in the bed every night, the softer pillow top means everyone sinks in a little, so expect less room than the width suggests.
What bedding fits a UK super king Harewood 4250?
You'll need super king sheets and a 260 x 220cm duvet. The mattress is 28cm deep with a pillow top, so check that fitted sheets have deep enough pockets to tuck under properly. Super king bedding is also pricier than king, so factor that in if you're replacing everything at once.
