Assessed from Hypnos's product page, captured September 2026, and from regular price comparison across our UK retail partners.
Choose this one if you want firm support with a little surface softness on top. The firm tension suits back and front sleepers, and heavier sleepers who sink through softer mattresses, although lightweight side sleepers may find it too unyielding at the shoulder and hip. At 31cm deep it should feel generously built, though you'll want deep fitted sheets to match. Yes, £1,499 is a serious spend, but Hypnos is a long-established British bedmaker and pocket spring construction at this level tends to justify the price. Availability is the catch: it's currently listed in UK King only, from one retailer.
Key Features & what's inside
Awaiting up to date specifications. Please check back later.
Who's it NOT for?
Lightweight side sleepers who need pressure relief at the shoulder may find the firm tension a little too much, even with the pillowtop. It's also not for you if you need a size other than UK King, as that's the only option currently listed, or if £1,499 stretches the budget.
Hypnos Bespoke Opal Pillowtop Mattress
How firm is the Hypnos Bespoke Opal Pillowtop mattress?
It's listed as firm. The pillowtop adds a softer sleeping surface over that firm base, so you get supportive tension underneath with a gentler initial feel. It's best suited to back and front sleepers, and those who prefer a solid, planted feel rather than sinking in.
How deep is the Hypnos Bespoke Opal Pillowtop mattress?
It measures 31cm deep, which is on the taller side. That extra height usually points to a substantial build, but do check your fitted sheets, as standard-depth ones may not stretch over a mattress this tall.
What sizes does the Hypnos Bespoke Opal Pillowtop come in?
It's currently listed in UK King only, from a single retailer, priced at £1,499. If you need a different size, you'd need to look at other models in the Hypnos range.
