Layer Details
Pillowtop
A pillowtop containing springs, cotton, wool and mohair. This gives a soft initial surface feel before you reach the firm support beneath.
Advanced Cortec Revolution Quad pocket spring system
An award-winning spring-within-a-spring design providing dynamic support that adapts to your body. In practice, that means support that responds to your shape rather than pushing back uniformly.
Posturfil pocket springs
1,000 Posturfil pocket springs form the core support layer. Each spring moves independently, which helps reduce disturbance when your partner moves.
High-density micro springs
Layers of 2,500 and 4,000 high-density micro springs. These fine springs contour more closely to your body than the larger springs below.
Natural fillings
Wool, hemp, flax, cotton and mohair. Natural fibres like these breathe better than foam, which helps if you tend to overheat at night.

Key benefits
- Space for two proper sleepers: At 150 x 200cm the UK king is 15cm wider than a UK double, which means fewer accidental elbows and less negotiating over the middle.
- Pocket springs limit partner disturbance: The 1,000 Posturfil pocket springs move independently, so if one of you gets up hours before the other, the movement is far less likely to travel across the bed.
- Extra length for taller sleepers: The UK king is 10cm longer than a UK double, a genuine relief if either of you is approaching six foot and used to feet meeting the footboard.
- Micro springs keep the firm feel even across the width: Layers of 2,500 and 4,000 high-density micro springs contour to each sleeper separately, so you both get the firm support without a ridge forming down the middle.
- Natural fillings across a bigger surface: Wool, hemp, flax, cotton and mohair breathe better than foam, useful when two bodies are warming a shared bed all night.
- A 33cm build that suits a king frame: The 33cm depth gives the pillowtop room to soften that first contact before you reach the firm springs, though you'll need deep-fitted king sheets.
This size suits you if...
You share the bed every night and a double has started to feel like a compromise, one of you keeps different hours and you want movement to stay on their side, or someone in the bed is tall enough that the extra 10cm of length over a UK double matters as much as the width.
Consider another size if...
Your bedroom is below the 2.7m x 2.9m we suggest as a minimum for a UK king. This mattress is only listed in the UK king, so if that's too large for your room, you'd need a different mattress rather than a smaller size of this one.

FAQ's
What size room do I need for the Pure Grande Pillowtop in a UK king?
We suggest a room of at least 2.7m x 2.9m for a UK king, which leaves enough space to walk round the bed and open drawers. In a new build master, measure after allowing for wardrobes: rooms that look generous on a floorplan can feel tight once fitted furniture goes in.
Is the UK king Pure Grande good for couples on different schedules?
Yes, and this is where the size and construction help each other. The UK king gives 75cm each for two people sharing, and the 1,000 Posturfil pocket springs move independently, so an early alarm on one side is less likely to wake the person still asleep on the other.
Does the Harrison Spinks Pure Grande Pillowtop come in sizes other than UK king?
No, it's listed in the UK king only, at 150 x 200cm. If you need a smaller or larger size you'd have to look at a different mattress. For most couples that's less of a problem than it sounds, as the UK king is the most popular upgrade size in the UK.
Is a UK king long enough for someone over six foot?
At 200cm, the UK king is 10cm longer than a UK double, which is usually enough for sleepers up to around 6ft 3in to stretch out without their feet hanging off. If either of you is taller than that, a longer bed would suit you better, and this mattress doesn't offer one.
How heavy and deep is the UK king version to handle?
Harrison Spinks doesn't publish a weight for this mattress, but at 150 x 200cm and 33cm deep with 12,500 springs and natural fillings, plan for two people to move it. If you're recovering from an injury or surgery, arrange help on delivery day rather than attempting the stairs alone.
