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, £3,599 is a lot, but Harrison Spinks is a long-established British maker and this is a deep, traditionally built mattress.

Who's it NOT for?
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 £3,599, 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, priced at £3,599. If you need a different size, this particular model won't suit, although Harrison Spinks makes other mattresses in a wider range of sizes.
