Vispring Bedstead Realm Firm Mattress

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

Choose this if you want a traditional, natural-fill mattress with a genuinely firm feel. The hand-nested calico pocket springs are stitched together by hand rather than glued, which means the spring unit stays stable and quiet over time. Layers of British fleece wool and cotton give a breathable sleeping surface, while the bamboo layer adds temperature regulation and hypoallergenic properties, useful if you run warm at night or react to synthetic fillings. Yes, it's a serious outlay, but you are paying for hand-nesting and entirely natural upholstery rather than foam. Vispring also offers this model in Soft, Medium and Extra Firm tensions, so check you are ordering the tension you actually want.

Back sleepers
Independent pocket springs and a genuinely firm feel give steady, even support under the whole body, which suits anyone who likes a flat, stable surface.

Warm sleepers
Wool breathes and wicks moisture, and the bamboo layer is chosen for temperature regulation, so the surface should feel drier and cooler through the night.

Allergy sufferers
Natural fillings of British fleece wool, cotton and bamboo replace foam, and the bamboo layer is chosen for its hypoallergenic properties, which suits those who react to synthetic materials.

Eco-conscious buyers
Natural fillings throughout, including British fleece wool, cotton and bamboo, mean you get entirely natural upholstery instead of foam, built around hand-nested springs.

Heavier sleepers
A firm feel over 1,326 steel pocket springs, each moving independently, gives resilient, stable support that should resist a roll-together dip under more weight.

Skip this if you like a soft, sink-in feel: this is a firm mattress, and lightweight side sleepers may find it puts a little too much pressure on hips and shoulders. It is also a slim profile at 21cm plus doming, so if you want a deep, hotel-style look, it will not deliver that.

How firm is the Vispring Bedstead Realm mattress?

Vispring describes this model as firm, with lasting support and a resilient, stable feel. It suits back and front sleepers who like a solid surface, although lightweight side sleepers may find it a little too firm. The same mattress is also made in Soft, Medium and Extra Firm tensions, so choose carefully at checkout.

How many springs does the Vispring Bedstead Realm Firm have?

It contains 1,326 hand-nested vanadium steel pocket springs, arranged in a single layer. Each spring sits in its own calico pocket and is stitched to its neighbours by hand, which means better edge-to-edge stability and less motion transfer than a glued spring unit.

How deep is the Vispring Bedstead Realm Firm mattress?

The overall depth is stated as 21cm, plus around 6cm of doming from the natural fillings, with a tolerance of plus or minus 2cm. That is slimmer than many modern mattresses, which is deliberate: it is designed to sit well on a bedstead frame.

What is the Vispring Bedstead Realm Firm made of?

The fillings are entirely natural: bonded and layered British fleece wool and cotton, plus a bamboo layer for temperature regulation and hypoallergenic properties. The springs are vanadium steel in calico pockets, with felt washers and high-quality ticking. There is no foam anywhere in the construction.

How much does the Vispring Bedstead Realm Firm 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 undeniably expensive, but the price reflects hand-nested calico springs and all-natural upholstery, a level of handwork most mattresses at lower prices simply do not include.
