Assessed from Vispring's published specification for this mattress, captured September 2026, and from regular price comparison across our UK retail partners.
You'd choose the Realm for its natural fillings and traditional build. There's no foam here: the comfort layers are British fleece wool, cotton and bamboo, which means better breathability than synthetic materials, a genuine help if you sleep warm. The 1,326 vanadium steel springs are hand-nested in calico pockets, a construction that lets each spring respond to your body independently, so you should feel supported without your partner's movement travelling across the bed. The choice of four spring tensions, from Soft to Extra Firm, means couples with different needs can specify what suits them. Yes, the price is high, but you're paying for hand-built construction and natural materials rather than marketing.
Key Features & what's inside
- Upholstery - Top layer. Bonded British fleece wool and cotton sit directly beneath you. Wool breathes and wicks moisture, which means a cooler, drier feel through the night than foam typically gives.
- Upholstery - Middle layer. A layer of British fleece wool adds soft, natural cushioning. It helps regulate temperature while giving a little give before you reach the springs.
- Upholstery - Layer. Bamboo brings a naturally breathable, moisture-managing quality to the fillings. It works alongside the wool to keep the sleep surface fresh.
- Upholstery - Bottom layer. Layered British fleece wool and cotton cushion the transition to the spring unit. This means you feel the support of the springs without any harshness.
- Spring system. A hand-nested calico pocket spring construction with 1,326 vanadium steel springs arranged in a single layer. Each spring moves independently, which means support that follows your shape and less disturbance from a partner shifting position.

Who's it NOT for?
If your budget is under £2,199, this isn't the mattress for you, and there are good options at a fraction of the price. It's also designed for a bedstead, and at 21cm it's slimmer than many expect, so if you want a deep, plush divan look, consider elsewhere. Standard tension leans firm, so lightweight side sleepers should look at the softer spring options.

How firm is the vispring realm mattress?
Vispring describes the Realm as offering firm, lasting support with a resilient, stable feel. That said, it's made in a choice of spring tensions, Soft, Medium, Firm and Extra Firm, so you can order the feel that suits your weight and sleeping position rather than accepting a single firmness.
How many springs does the vispring realm have?
It contains 1,326 hand-nested vanadium steel pocket springs in a calico construction, arranged in a single layer. Hand-nesting means the springs are sewn together by hand rather than glued, which helps each one respond independently to your body.
What sizes does the vispring realm bedstead mattress come in?
It's available in UK Double, UK King and UK Super King, with prices ranging from £2,199 to £3,269 depending on the size you choose.
How deep is the vispring realm mattress?
The overall depth is 21cm, plus around 6cm of doming (give or take 2cm), where the natural fillings sit slightly proud of the borders. It's a slimmer profile than many modern mattresses, which suits a bedstead well.
Is the vispring realm made with natural materials?
Yes. The fillings are British fleece wool, cotton and bamboo, layered over vanadium steel pocket springs in calico pockets, finished with high-quality ticking and felt washers. There's no memory foam or synthetic comfort layer, which generally means a cooler, more breathable sleep surface.
