Harrison Spinks Pure Response Firm Mattress

Assessed from the product page published by Furniture Village, captured September 2026, and from regular price comparison across our UK retail partners.

Pocket springs move independently of one another, which means less motion transfer when a partner shifts in the night and support that follows the shape of your body rather than pushing back as one unit. The firm tension suits sleepers who want to lie on the mattress rather than in it, and at 24cm deep it should sit comfortably with standard UK fitted sheets. The starting price is a step up from budget pocket sprung options, but Harrison Spinks is a long-established British maker, and that pedigree is part of what you're paying for. Just check the tension carefully before ordering, as firm is a genuine commitment.

Back sleepers
The firm tension keeps you lying on top of the surface rather than sinking in, which suits anyone who likes a flat, supported feel on their back.

Front sleepers
A firm surface helps stop the middle of your body dropping too far down, so lying on your front feels level and supported.

Couples
Pocket springs move independently of one another, which means less motion transfer when your partner shifts in the night, and the range includes King and Super King.

Heavier sleepers
Firm tension with independently moving pocket springs gives support that follows your body shape, so the mattress should resist sinking when more weight presses down.

Skip this one if you're a lightweight side sleeper: a firm tension can create pressure at the shoulder and hip rather than letting them settle in. It's also not for anyone wanting a UK Double, as that size isn't listed, or for buyers who prefer the contouring hug of memory foam.

How firm is the Harrison Spinks Pure Response Firm mattress?

It's listed as firm, the tension aimed at back and front sleepers and those who prefer a supportive, on-top-of-the-mattress feel. Heavier sleepers often get on well with firm mattresses too. Lightweight side sleepers may find it slightly too solid for comfortable pressure relief at the shoulder and hip.

What sizes does the Pure Response Firm come in?

Retailer listings show four sizes: UK Single, UK Small Double, UK King and UK Super King. A standard UK Double isn't listed, which is a little unusual, so double-check with the retailer if that's the size you need.

How deep is the Harrison Spinks Pure Response Firm mattress?

It's 24cm deep. That's a fairly standard depth, which means most regular UK fitted sheets should go on without a struggle, and no extra-deep bedding is required.

Is the Pure Response Firm a pocket spring mattress?

Yes. Pocket springs are individually wrapped coils that compress independently, which means the mattress responds to your body shape and transfers less movement across the bed than an open coil design. We don't have confirmed details of the spring count or comfort layers for this model, so ask the retailer if that matters to you.
