Harrison Spinks Pure Grande Zip and Link Pillowtop Medium/Firm Mattress

Assessed from mattress data provided by our UK retail partners, captured September 2026, and from regular price comparison across those retailers.

The main reason to consider this mattress is the zip and link construction. The two halves zip together into one UK King, which means moving it up narrow stairs or around tight landings is far more manageable than with a one-piece mattress of this depth, and couples can unzip it if their needs differ. The pocket springs give localised support, so your hips and shoulders are held where they actually rest. The pillowtop adds a slightly softer feel on top of the medium firm base, a sensible pairing for back and combination sleepers. Yes, it costs a lot, but Harrison Spinks is a long-established British maker and this is a deep, traditionally built mattress.

Couples
The zip and link design splits into two halves, so partners with different needs can unzip the bed and each have their own side.

Back sleepers
A pillowtop sits on the medium firm base, giving a slightly softer surface feel that suits lying flat on your back.

Combination sleepers
Pocket springs give localised support while the pillowtop softens the surface, which suits switching positions through the night on a medium firm base.

Side sleepers
Pocket springs hold the hips and shoulders where they rest, while the pillowtop adds a softer layer on top for those pressure points.

If you sleep hot and prefer a low-profile mattress, the 33cm depth and pillowtop may feel like more bed than you need. It's only available in UK King, so anyone after a different size will need to look elsewhere. And at a premium starting price, budget-conscious buyers should probably pass.

What does zip and link mean on a mattress?

A zip and link mattress comes as two separate halves that zip together to form one larger mattress. It makes delivery and moving easier, particularly up narrow staircases, and the halves can be separated if needed. The Pure Grande uses this design in its UK King size.

How firm is the Harrison Spinks Pure Grande?

It's rated medium firm, which suits most back and combination sleepers. The pillowtop adds a slightly softer surface feel over the supportive pocket spring base, so it shouldn't feel hard against your shoulders and hips.

How deep is the Pure Grande Pillowtop mattress?

It's 33cm deep, which is a substantial mattress. Check that your fitted sheets can accommodate a deep mattress before buying, as standard sheets can struggle at this depth.

What sizes does the Pure Grande Zip and Link come in?

It's listed in UK King only. If you need a different size, this particular model won't suit, although Harrison Spinks makes other mattresses in a wider range of sizes.
