Why should you choose this mattress?
This is a good pick if you want a firm mattress that isn't harsh on top. The pillow top and the silk, polyester and cotton fibre fillings add cushioning above the 1000 individual pocket springs, so the surface should feel a little softer than the firm rating suggests. Each spring sits in its own fabric pocket, and the Calibar Edge has firmer outer springs for steadier edges. It's handcrafted in the UK and approved by the National Bed Federation. It suits most back and front sleepers, although side sleepers who want a lot of give may find it too firm.
Key features & layer details
Comfort fillings
A blend of silk and polyester fibres sits at the surface. It gives the top a soft, comforting feel over the firmer layers below.
Additional fillings
Soft white fibres and a polyester and cotton blend add breathability and cosy comfort. That helps the surface feel cushioned without losing air flow.
Polyester fibre pad
A densely packed polyester fibre pad finishes the build. It adds to the firm feel, so the mattress stays supportive.
Pocket spring core
A core of 1000 individual pocket springs, each in its own fabric pocket. The springs move independently, so the mattress supports you closely across its surface.

Best suited for?
Back sleepers
The firm rating and 1000 individual pocket springs give close, supportive feel across the surface, while the pillow top keeps it from feeling harsh.
Front sleepers
A firm feel with a densely packed polyester fibre pad keeps the mattress supportive, so your body is held up rather than sinking in.
Couples
Each spring sits in its own fabric pocket and moves independently, and the range runs up to a UK super king for plenty of shared space.
Warm sleepers
Soft white fibres and a polyester and cotton blend add breathability, so the cushioned surface keeps air flowing rather than trapping heat.
If you prefer sleeping on a soft or medium mattress, this might not be the best choice. It's rated firm, and the pillow top only softens the surface slightly. Lighter side sleepers may want more give at the shoulders and hips. It's also single-sided, so you can't flip it, only rotate it.
Save on an earlier or ex-display model
Some retailers still sell the earlier version of this mattress, or ex-display and returned stock at a lower price. These are the sizes where it costs less than the current model's best price.
