Assessed from mattress data provided by our UK retail partners, captured September 2026, and from regular price comparison across those retailers.
Pocket springs move independently of one another, which means less disturbance when a partner turns over during the night, and the pillowtop adds a built-in comfort layer so you get cushioning without needing a separate topper. At 31cm this is a deep mattress, and that generally translates to a more substantial, hotel-style feel, although you'll want to check your fitted sheets stretch to that depth. The zip and link construction is a practical touch: two halves are easier to carry upstairs than one heavy king-size mattress. Medium firm suits most sleepers, although lightweight side sleepers may find it a touch firm through the shoulder.

Who's it NOT for?
If your budget sits under four figures, this isn't the one, and there are decent pocket sprung options for less. It's also currently listed in UK King only, so shoppers needing a different size will have to look elsewhere. Fans of the contouring, sink-in feel of memory foam may find a sprung pillowtop too springy.

How firm is the Hypnos Bespoke Opal mattress?
It's rated medium firm, which means noticeable support with some give from the pillowtop layer. That balance suits most back and combination sleepers, although very lightweight side sleepers sometimes prefer something a little softer.
What is a zip and link mattress?
A zip and link mattress comes as two separate halves joined together with a zip. That makes it easier to move through narrow hallways and up stairs, and the halves can be unzipped if you ever want two individual mattresses.
How deep is the Hypnos Bespoke Opal?
It's 31cm deep, which is deeper than many mattresses. It gives a substantial, generous feel, but do check that your fitted sheets are designed for deep mattresses before it arrives.
What sizes does the Hypnos Bespoke Opal come in?
It's currently listed in UK King only, priced from £1,999. If you need a different size, you'll need to look at other models.
