Assessed from Vispring's published specification for this mattress, captured September 2026, and from regular price comparison across our UK retail partners.
Choose the Imperial if you want traditional craftsmanship with entirely natural fillings. The 1,720 vanadium steel pocket springs in the 150 x 200cm size are hand-nested in calico and move independently, which means the mattress responds to each sleeper separately and limits partner disturbance. Horsehair in the support layer adds durability and natural spring, while the wool, cotton and bamboo top gives softness with real breathability, useful if you tend to overheat at night. Because Vispring offers four spring tensions, from Soft to Extra Firm, you can match the mattress to your weight and sleeping position rather than settling for one fixed feel. Yes, the price is high, but this is genuinely made-to-order construction.
Key Features & what's inside
- Top upholstery. Layered British fleece wool and cotton with bamboo, which gives exceptional softness directly beneath you. These natural fibres are highly breathable, so the surface stays temperate rather than trapping heat.
- Support layer. Horsehair, a traditional filling prized for durability and resilience. It acts as a natural spring beneath the softer top layers, helping the mattress keep its shape over time.
- Spring layer. Hand-nested calico pocket springs made from vanadium steel, with 1,720 springs in the 150 x 200cm size. It's a single layer of springs that move independently, which means support adapts to your body and you feel less of your partner's movement.
- Base upholstery. Bonded British fleece wool and cotton with a built-in wool pad. This safeguards the mattress against wear from beneath, protecting the fillings where they meet the bedstead.

Who's it NOT for?
This isn't the mattress for anyone on a tight budget: at £4,159 upwards it costs more than many people spend on a whole bedroom. It's also relatively shallow at 21cm plus doming, so if you want a very deep, boxy modern look, or memory foam contouring, look elsewhere.

How firm is the Vispring Imperial mattress?
Vispring describes the feel as balanced support, and the mattress is available in Soft, Medium, Firm and Extra Firm spring tensions, so firmness depends on the tension you choose. Retail listings anchor it as Medium Firm, although Vispring's page doesn't state which tension that corresponds to.
What is the Vispring Imperial mattress made of?
The fillings are entirely natural: British fleece wool, cotton and bamboo in the top upholstery, horsehair in the support layer, and bonded wool and cotton at the base. The springs are vanadium steel pocket springs, hand-nested in calico, all finished in high-quality ticking.
How many springs does the Vispring Imperial have?
It has 1,720 pocket springs in the 150 x 200cm size, arranged in a single hand-nested layer. Each spring sits in its own calico pocket and moves independently, which helps the mattress respond to your body shape and reduces disturbance from a partner.
How deep is the Vispring Imperial mattress?
The overall depth is 21cm, plus around 6cm of doming (give or take 2cm) from the generous natural fillings. That makes it shallower than many deep modern mattresses, which suits bedsteads and existing fitted sheets, though it won't give a tall, boxy profile.
How much does the Vispring Imperial mattress cost?
Prices range from £4,159 to £6,119 depending on size, with UK Double, King and Super King available. It's a substantial outlay, but you're paying for hand-nested calico springs, all-natural fillings and made-to-order construction in your choice of spring tension.
