Layer Details
Advanced Cortec Quad pocket springs
This is the main pocket spring system, described as award-winning. It gives the mattress its firm, supportive base, so you lie on top of the surface rather than sinking into it.
Micro spring layer
A layer of 2,500 high-density micro springs sits above the main system. It adds a finer level of cushioning, which helps ease pressure and takes some of the edge off the firm tension.

Key benefits
- Room to sleep apart while sharing: At 75cm each for two people sharing, you can settle into your own tension-supported patch without negotiating over the middle.
- Less disturbance across the width: Pocket springs compress individually, and the UK king's extra width puts more distance between you, so an early alarm on one side travels less.
- Length for taller sleepers: The 200cm length gives anyone approaching six foot proper clearance on a firm surface, where feet hanging off the end are felt more than on softer beds.
- Firm support with space to change position: Pregnancy, injury recovery or restless nights all involve repositioning, and a firm 150cm-wide surface makes shifting and propping pillows easier without waking a partner.
- Standard bedding, standard depth: At 24cm deep, standard UK king fitted sheets should go on without a struggle.
This size suits you if...
You share the bed every night and want more personal space than a smaller size allows, especially if one of you keeps different hours and the other feels every exit. It also suits you if either partner is tall, since the 200cm length is part of the upgrade, or if you're expecting a baby and need room to prop pillows and shift position on a surface firm enough to push against.
Consider another size if...
Your room is under our suggested 2.7m x 2.9m minimum for a UK king, or you sleep alone. The UK small double would suit you better, and we suggest at least 2.4m x 2.8m for that size.

FAQ's
How much space does each person get on a king size Pure Response Firm?
You get 75cm each for two people sharing, across the mattress's 150cm width. On a firm pocket sprung surface that matters, because you lie on the mattress rather than sinking into it, so elbow room is what stops you noticing each other. Springs compressing independently helps too, keeping one sleeper's movement from carrying across.
What size room do I need for the Pure Response Firm in a UK king?
We suggest a room of at least 2.7m x 2.9m for a UK king. That's tighter than it sounds in a new build master once fitted wardrobes go in, so measure the usable floor rather than the room on the plan, and allow walking space on both sides if you each want your own bedside table.
Is the UK king Pure Response Firm long enough for a tall sleeper?
At 200cm (the full size is 5ft x 6ft 6in), it's 10cm longer than a UK double, which is a genuine relief for anyone approaching six foot. Firm mattresses make overhang more noticeable because there's little give at the edge, so if one of you is tall, the extra length here does as much as the width.
Does the Harrison Spinks Pure Response Firm come in a UK double?
No, a UK double isn't listed for this mattress. If a double is roughly the size you had in mind, the UK king is 15cm wider and 10cm longer, and needs a slightly larger room: we suggest at least 2.7m x 2.9m. You can compare the retailers listed on this page for the UK king.
Should a couple size up from this UK king to the super king?
The UK king is 30cm narrower than the UK super king, and both are the same 200cm length. If a dog routinely joins you, or you find you still touch across the middle, the extra width is what you're paying for. We suggest at least 3m x 2.9m of room for the UK super king, so check your space first.
