Vispring Bedstead Realm Medium Mattress

Assessed from Vispring's published specification for this mattress, captured September 2026, and from regular price comparison across our UK retail partners.

This is a mattress built around natural materials and hand work rather than foam and gimmicks. The calico pocket springs are hand-nested, a traditional technique where springs sit closely together in cotton pockets, giving precise, independent support across the surface. The upholstery is British fleece wool, cotton and bamboo, which means the mattress breathes well and regulates temperature naturally. If you sleep hot, that matters more than any cooling gel. The 21cm depth, with roughly 6cm of doming on top, keeps the profile sensible for a bedstead frame. Yes, the price is high, but you are paying for hand-nested springs and all-natural upholstery, a level of construction most mattresses at lower prices simply do not attempt.

Warm sleepers
Wool, cotton and bamboo layers with no synthetic foam breathe well and regulate temperature naturally, so you should feel less clammy through the night.

Couples
Each of the 1,326 hand-nested pocket springs moves independently, which means less disturbance when your partner turns over.

Back sleepers
A firm, stable surface with resilient support from the pocket springs helps keep you evenly held without sinking in too far.

Eco-conscious buyers
Upholstery of British fleece wool, cotton and bamboo with no synthetic foam suits anyone who wants natural materials in their bed.

Combination sleepers
Springs that follow your shape and an even, resilient response make changing position easy, as the surface does not cradle or hold you in place.

If you like a soft, cradling, sink-in feel, this is unlikely to suit you: Vispring describes it as firm, lasting support, and lightweight side sleepers in particular may find it a little unyielding. At 21cm plus doming, it is also shallower than some buyers expect at a premium starting price, and the cost itself puts it out of reach for many budgets.

Is the Vispring Bedstead Realm Medium actually medium or firm?

Confusingly, both labels appear. It's listed as Medium, but Vispring's own page describes firm, lasting support with a resilient, stable feel. Go by the brand's description: expect a firmer, supportive surface rather than a true middle-of-the-road medium, and check spring tension options when ordering.

How many springs does the Vispring Bedstead Realm have?

It contains 1,326 hand-nested vanadium steel pocket springs in a single layer, held in calico pockets. Hand-nesting packs the springs closely together, which means more responsive, independent support across the whole mattress than machine-made units typically manage.

What is the Vispring Bedstead Realm mattress made of?

The upholstery is entirely natural: bonded British fleece wool and cotton on top, a layer of British fleece wool, a bamboo layer, then layered wool and cotton beneath. Under that sits the calico pocket spring unit. There is no memory foam or synthetic filling.

How deep is the Vispring Bedstead Realm mattress?

The overall depth is 21cm, plus around 6cm of doming on top, give or take 2cm. That slimmer profile is deliberate, as the mattress is designed for bedsteads, where a shallower build sits better within the frame.

How much does the Vispring Bedstead Realm cost?

It depends on the size you choose, and the price table on this page shows the current price for each size. It comes in UK Single, Double, King and Super King. It is a serious outlay, but it reflects hand-nested calico springs and all-natural British wool, cotton and bamboo upholstery.
