The Vispring Sublime Superb is listed here in the Firm tension, one of four Vispring offers (Soft, Medium, Firm and Extra Firm), so you can match the feel to your build and sleeping position. It is available in UK King and UK Super King. It costs serious money, but it buys materials such as horsetail, Shetland wool, silk and mohair, and a construction method most mattresses simply do not use. The 23cm depth, plus roughly 6cm of natural doming, gives a substantial, hotel-like profile.

Why should you choose this mattress?
Everything in the sleep surface is natural fibre: British fleece wool, horsetail, silk, mohair and cotton, which means the mattress breathes well and helps regulate temperature. If you sleep hot, that matters more than any cooling gel gimmick. Beneath the upholstery sit two layers of hand-nested calico pocket springs made from vanadium steel, 2,520 of them in the 150 x 200cm size, which means each spring responds independently to your body rather than the bed moving as one unit. The borders are reinforced with coir and wool and four rows of hand side-stitching, so the edges stay supportive over time. In Firm tension, it suits heavier sleepers and back sleepers who want a stable, supportive feel.
Key features & layer details
Upholstery - Top Layer
British fleece wool sits alongside hand-teased horsetail blended with real Shetland wool, silk and mohair, plus a Shetland wool and cotton blend, all encased in high-quality ticking. These natural fibres wick moisture and breathe, which means a cooler, drier sleep surface than synthetic foams tend to give.
Springs
A two-layer construction of hand-nested calico pocket springs made from vanadium steel, with 2,520 springs in the 150 x 200cm size. Two layers working together means finer, more progressive support: gentle at first contact, firmer as you settle in.
Borders
The borders are upholstered with protective coir and wool and finished with four rows of hand side-stitching. This anchors the springs to the edge of the mattress, which means firmer edge support and less of that roll-off feeling when you sleep near the side.

Best suited for?
Heavier sleepers
Two layers of hand-nested vanadium steel pocket springs give progressive support that firms up as you settle, which suits heavier bodies in the Firm tension.
Back sleepers
The Firm tension and independently responding pocket springs give a stable, supportive feel that keeps a back sleeper held level through the night.
Warm sleepers
A sleep surface made entirely of natural fibres such as wool, horsetail, silk and mohair breathes and wicks moisture, so the bed stays cooler and drier.
Couples
Each spring responds on its own rather than the bed moving as one unit, and the King and Super King sizes leave plenty of room for two.
Combination sleepers
Reinforced borders with four rows of hand side-stitching give firm edge support, so moving across the bed or sleeping near the side feels secure.
This is a firm tension, so lightweight side sleepers may find it puts too much pressure on shoulders and hips; Vispring's softer tensions would suit them better. It is also a very significant outlay, and only UK King and Super King sizes are listed, so smaller beds are out. Anyone wanting a bed-in-a-box price should look elsewhere.
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.

FAQ's
How firm is the Vispring Sublime Superb?
Vispring makes the Sublime Superb in four tensions: Soft, Medium, Firm and Extra Firm. This is the Firm version, which generally suits back sleepers and heavier body weights. If you are a lighter side sleeper, one of the softer tensions is likely to feel more comfortable.
How many springs does the Vispring Sublime Superb have?
It uses a two-layer, hand-nested calico pocket spring construction made from vanadium steel, with 2,520 springs in the 150 x 200cm size. Spring counts vary by mattress size, so other sizes will differ from that figure.
What is the Vispring Sublime Superb made of?
The upholstery uses British fleece wool, hand-teased horsetail blended with Shetland wool, silk and mohair, and a Shetland wool and cotton blend. The borders contain coir and wool with four rows of hand side-stitching, and the springs are vanadium steel in calico pockets.
How deep is the Vispring Sublime Superb mattress?
The stated depth is 23cm, with around 6cm of doming on top (give or take 2cm). Doming is the natural pillowing of the fibre fillings, so the overall profile feels deeper than the base measurement suggests. Deep fitted sheets are a sensible buy.
What sizes does the Vispring Sublime Superb come in?
It's listed in UK King and UK Super King. If you need a smaller size, this particular model may not be an option.
