Choose this if you want a firm feel without the hard, unyielding surface that firm mattresses sometimes have. The pillowtop design adds a cushioned surface layer above the pocket springs, which means the springs handle support while the top handles comfort. Pocket springs move independently, so you're less likely to feel a partner shifting during the night. At 30cm deep it's a properly substantial mattress, one that may need deep fitted sheets. Yes, £1,899 is a lot of money, but Harrison Spinks is a long-established British manufacturer and a mattress at this depth and spec is built as a long-term buy. We currently list it in UK King through one retailer.
Key Features & what's inside
Awaiting up to date specifications. Please check back later.
Who's it NOT for?
If you're a lightweight side sleeper, a firm mattress like this may not let your shoulders and hips sink in enough, which can mean pressure points. It's also a poor fit for tight budgets at £1,899, and if you need a size other than UK King, it isn't currently listed in one.

How firm is the Harrison Spinks Pure Sensation Pillowtop mattress?
It's listed as firm. The pillowtop adds a slightly softer surface layer, so it shouldn't feel harsh, but the underlying support is firm. That suits back and front sleepers best, and heavier sleepers who need extra pushback.
How deep is the Pure Sensation Pillowtop Firm mattress?
It's 30cm deep, which is a substantial depth. You may need deep fitted sheets, so check your bedding before it arrives.
What sizes does the Pure Sensation Pillowtop Firm come in?
It's currently listed in UK King only, at £1,899, through one retailer. If you need a different size, it's worth checking with the retailer directly, as availability can change.
What type of mattress is the Pure Sensation Pillowtop Firm?
It's a pocket spring mattress with a pillowtop. Pocket springs are individually wrapped coils that respond to each part of your body separately, which means better motion isolation than open coil designs, so you feel a partner's movement less.
