12 gauge (2.95mm) Double Cone Springs 4" / Pack of 50

12 Gauge (2.95mm) Double Cone Upholstery Coil Springs, 3" to 6"

The 12 Gauge (2.95mm) Double Cone Upholstery Springs are made for traditional upholstery, furniture restoration and sprung furniture construction where lighter, more flexible support is required.

Manufactured from 2.95mm spring wire, these traditional hourglass-shaped upholstery springs are particularly suitable for sprung sofa backs, armchair backs and upholstered furniture arms.

As the lightest wire gauge in Status Fabrics' double cone spring range, they offer a more responsive spring action than the heavier 9 and 10 gauge alternatives.

Available in 3", 4", 5" and 6" heights, these upholstery coil springs are supplied individually for repairs or in packs of 50 for professional workshops.

Features

• 12 gauge spring wire: Approximately 2.95mm diameter for lighter spring resistance.
• Double cone construction: Traditional hourglass shape suitable for appropriate upholstery applications.
• Four available heights: 3", 4", 5" and 6".
• Responsive spring action: Particularly useful in sprung backs and arms.
• Traditional upholstery compatibility: Suitable for webbing-supported, hand-tied spring foundations.
• Furniture restoration: used for replacing matching original springs in period furniture.
• Individual or bulk purchasing: Available singly or in packs of 50.

Choosing Between 9, 10 and 12 Gauge Upholstery Springs

Selecting the correct spring gauge is important when restoring traditionally upholstered furniture.

9 Gauge Double Cone Springs

Manufactured from approximately 3.6mm wire, these are the thickest and generally firmest double cone springs in the Status Fabrics range. They are normally selected for supportive traditional seat foundations.

10 Gauge Double Cone Springs

Manufactured from approximately 3.2mm wire, these provide a middle option for smaller seats, softer traditional seating and suitable sprung backs and arms.

12 Gauge Double Cone Springs

Manufactured from approximately 2.95mm wire, these offer the lightest spring resistance in the range and are primarily intended for sprung furniture backs and upholstered arms.

When replacing existing springs, matching the original wire gauge, uncompressed height and spring arrangement is normally the best starting point.

A 12 gauge spring should not be substituted directly for a heavier seat spring simply because its height is similar.

How Are Traditional Double Cone Springs Installed?

Double cone springs are commonly incorporated into traditionally upholstered furniture using a foundation of strong upholstery webbing.

Each spring is positioned and securely attached to the supporting webbing before being hand tied using suitable spring-lashing cord.

The tying arrangement helps control the spring movement, maintain alignment and establish the required shape of the sprung back or upholstered arm.

Once correctly secured, the spring foundation is covered with suitable upholstery hessian, followed by the appropriate padding and filling materials.

Correct installation is especially important with lighter 12 gauge springs, as excessive compression or incorrect tying can alter their intended response.

Essential Materials for Traditional Spring Upholstery

For a complete upholstery spring installation, we recommend the following complementary materials.

Laidcord Spring-Lashing Cord

Traditional flax upholstery lashing cord used to tie and stabilise individual coil springs. Proper spring tying helps maintain the intended shape and prevents unwanted movement within the spring foundation.

Upholstery Hessian

A traditional upholstery covering material fitted over the completed spring foundation. Hessian provides a supporting layer between the springs and the upholstery fillings.

Felts & Wadding

Used to build up and soften the upholstery layers above the spring foundation, helping create a smooth, comfortable finish for backs and arms.

Together, these materials form important components of a traditionally constructed upholstery foundation.

Choosing the Correct Spring Height

supplies 12 gauge double cone springs in four heights:

• 3", approximately 76mm.
• 4", approximately 102mm.
• 5", approximately 127mm.
• 6", approximately 152mm.

The appropriate height depends on the depth of the furniture construction, the original spring specification and the required finished upholstery shape.

Traditional upholstery springs are normally compressed and shaped during the hand-tying process, so the original free height will generally differ from the final installed height.

When restoring antique furniture, compare replacement springs with an undamaged original wherever possible.

Are 12 Gauge Double Cone Springs Suitable for Seats?

Although double cone springs are widely used in traditional seating, 12 gauge springs are primarily intended for furniture backs and arms.

Their lighter wire provides a more flexible response but will not necessarily deliver the resistance required for a principal seating foundation.

For firmer seat support, the 9 Gauge Double Cone Springs or 10 Gauge Double Cone Springs may be more appropriate, depending on the furniture construction.

Always consider the original spring arrangement rather than selecting a replacement based solely on height.
