Who is the Vispring Signatory for?
The Signatory suits sleepers who prefer a firmer, more structured surface and who value natural fillings over synthetic foams. It is positioned in Vispring’s Luxe Collection, and it is the model the brand points to for those who desire a firmer feel. Shetland wool, Austrian Moosburger horsetail, cashmere, organic cotton and British fleece wool make up the upholstery, so the mattress leans on natural fibers for both softness and breathability rather than on memory foam layers.
It also suits buyers who want control over firmness. The Signatory is offered in four spring tensions: Soft, Medium, Firm and Extra Firm. That range means you can match the mattress to how you sleep instead of accepting a single fixed feel. Because the fillings are exclusively natural and the springs are hand-nested in calico pockets, it appeals to people who care about traditional British mattress construction.
What does the specification sheet say?
The Signatory’s headline numbers are straightforward. It uses a two-layer hand-nested calico pocket spring construction, and in the 150 x 200cm size (5ft x 6ft 6in) it features 2,664 springs. The overall mattress depth is 23cm (9.1 inches) plus 6cm (2.4 inches) of doming, with a tolerance of plus or minus 2cm (0.8 inches). The borders are upholstered with protective coir and wool, finished with four rows of hand side-stitching, horizontal handles for movement, and air vents for breathability.

How does the two-layer spring build shape the feel?
The Signatory’s feel is defined by its two spring layers and its choice of tension. Vispring describes the mattress as structured yet naturally breathable, and the two-layer arrangement is there for consistent support that contours to the body. The four tensions give you a real decision to make: Soft and Medium for a more enveloping surface, Firm and Extra Firm for a rigid, upright feel. Since the mattress is aimed at those who want a firmer feel, the Firm and Extra Firm tensions are the natural fit for sleepers who want little sink.
The natural fillings play into that structure. Hand-opened Austrian Moosburger horsetail is included for extra bounce and comfort, while organic cotton and Shetland wool give a soft, natural finish. Hand-teased Shetland wool blended with cashmere and British fleece wool add further loft, and hand-tied woollen tufts and twine hold the structure together over time. The high-quality ticking is chosen for durability and breathability, and the air vents in the borders work with the natural fillings to keep air moving through the mattress.
What is the Signatory made of, layer by layer?
Vispring states that the Signatory is crafted exclusively from natural fillings. The upholstery list includes blended real Shetland wool and cotton, hand-opened Austrian Moosburger horsetail, hand-teased real Shetland wool blended with cashmere, and British fleece wool. There is no synthetic foam comfort layer in the specification. The springs sit in calico pockets and are hand-nested in two layers, and the whole mattress is encased in high-quality ticking.
The border construction adds to the durability story. Protective coir and wool line the borders, four rows of hand side-stitching reinforce the edges, horizontal handles make the mattress easier to move, and air vents improve breathability. Hand-tied woollen tufts and twine keep the fillings in place so the surface keeps its shape.

How does the Signatory compare with the Saatva Classic?
Both mattresses are spring-based and both let you choose firmness, but they are built differently and bought differently. The Signatory uses exclusively natural fillings and a two-layer hand-nested calico pocket spring system, with 2,664 springs in the 150 x 200cm size. The Saatva Classic is an innerspring mattress with a dual-coil design made of triple-tempered recycled carbon steel, a 3 inch Euro pillow top, and Lumbar Zone technology for spinal alignment. It is offered in Plush Soft (3/10), Luxury Firm (5-7/10) and Firm (8/10).

Who should buy the Signatory, and who should buy the Saatva Classic?
Buy the Vispring Signatory if you want a firmer, structured mattress built entirely from natural fillings, and if you value hand-nested pocket springs, hand side-stitching and hand-tied tufts. It is the choice for sleepers who want to pick between four spring tensions and who prefer wool, horsetail and cashmere over foam. The Signatory sits in Vispring’s Luxe Collection and is aimed at those who desire a firmer feel with natural breathability.
Buy the Saatva Classic if you want a mattress with a 365-night home trial, a lifetime warranty, and free white-glove delivery that includes setup and old mattress removal. It suits sleepers who want three clearly graded comfort levels, chiropractor-endorsed Lumbar Zone support, and a dual-coil design with over 1,000 recycled carbon steel coils in full size and up. It is also the practical pick for couples who cannot agree on firmness, since Luxury Firm is designed for all sleep positions.
What does the Signatory cost, and what are the policies?
Vispring does not list a price for the Signatory on the page reviewed here, and the brand directs buyers to request a brochure or try the mattresses in person. That is typical for a hand-built British mattress sold through showrooms. The Saatva Classic, by contrast, is priced transparently online and carries a 365-night home trial, a lifetime warranty, and free white-glove delivery with in-room setup and old mattress removal at no additional cost. Check the current price on the Saatva site to see how the two compare in your size.
Who should NOT buy the Vispring Signatory?
Skip the Signatory if you want a soft, body-hugging feel. It is built for those who desire a firmer feel, and even its Soft tension is part of a structured, natural build rather than a plush foam top. Skip it too if you want to order online with a long home trial and free returns, since Vispring routes buyers through brochures and showroom trials rather than a published trial period. And skip it if you prefer synthetic foams or a pillow top, because the Signatory’s upholstery is exclusively natural fillings with no foam comfort layer.
Is the Saatva Classic the better alternative?
For most online buyers, yes. The Saatva Classic gives you the same spring-based support with a published 365-night home trial, a lifetime warranty, and free white-glove delivery that includes setup and removal of your old mattress. It offers three comfort levels, a 3 inch Euro pillow top, Lumbar Zone technology, and a breathable organic cotton cover treated with Guardin botanical antimicrobial treatment. It is CertiPUR-US certified and GREENGUARD Gold certified, and it is endorsed by the American Chiropractic Association. If you want natural fillings above all, the Signatory remains the pick; if you want trial length, warranty and delivery certainty, the Saatva Classic wins.
Verdict
The Vispring Signatory is the pick for sleepers who want a firmer, all-natural mattress with four spring tensions. The Saatva Classic is the pick for buyers who want a 365-night trial, a lifetime warranty and free white-glove delivery.
