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.
Key Features & what's inside
- Top upholstery layer. Bonded British fleece wool and cotton sit directly beneath you, which means a breathable, naturally temperature-regulating sleep surface. Wool wicks moisture away, so you should feel less clammy than on foam.
- Middle upholstery layer. A layer of British fleece wool adds cushioning depth. It softens the surface slightly without undermining the firm, stable support beneath.
- Bamboo layer. Bamboo brings extra breathability and resilience to the comfort layers. It is a naturally airy fibre, helpful if you tend to overheat at night.
- Bottom upholstery layer. Layered British fleece wool and cotton cushion the transition between you and the springs. This stops you feeling the spring unit directly while keeping the response even.
- Spring system. 1,326 hand-nested vanadium steel pocket springs, arranged in a single layer within calico pockets. Because each spring moves independently, you get support that follows your shape and less disturbance from a partner turning over.

Who's it NOT for?
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 this 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?
Prices run from £1,602.25 to £3,150 depending on size, with UK Single, Double, King and Super King available. That is a serious outlay, but it reflects hand-nested calico springs and all-natural British wool, cotton and bamboo upholstery.
