300g Compressed Polyester Spring Insulator for Upholstery

This 300g compressed polyester spring insulator is designed to create a protective upholstery layer over furniture springs before foam, felt or other padding materials are fitted above.

Supplied 40" wide in a 30 metre roll and approximately 12mm thick, the dense compressed polyester helps separate the spring system from the upholstery fillings above it.

Unlike soft polyester cushion wrap, which is used primarily to add loft and softness around foam cushions, this material is compressed to provide a firmer and more stable spring insulation layer within the furniture construction.

What Is a Spring Insulator Used For?

An upholstery spring insulator sits above the furniture spring system and below the main padding or cushioning layers.

Its purpose is to create a protective barrier between the springs and the materials positioned above them.

Without a suitable insulation layer, foam, felt or other upholstery fillings may press into spaces between the springs or come into repeated contact with spring wire and connecting components.

A compressed polyester spring insulator helps create a more consistent foundation for the upholstery layers above.

Typical applications include:

• Sofa seat construction
• Armchair restoration
• Traditional sprung chairs
• Upholstered benches
• Footstools
• Furniture refurbishment
• Replacement spring foundations
• New upholstered furniture manufacture

Why Use a Compressed Polyester Layer Over Springs?

Protects the Upholstery Layers Above

Furniture springs create a flexible support system, but the individual wires and spaces between springs can create concentrated contact points.

A spring insulator provides a barrier between this structure and the foam, felt or other padding above.

This can help reduce direct rubbing and prevent softer upholstery materials from working down between the springs.

Creates a More Even Upholstery Foundation

The compressed polyester spans across the spring system to provide a more consistent surface for subsequent upholstery layers.

This is particularly useful where the furniture construction combines springs with foam, felt or other padding materials.

Dense Rather Than Lofty

This 300g spring insulator should not be confused with soft Dacron cushion wrap.

Standard Polyester Wadding is primarily used to soften and round foam cushions.

Compressed spring insulation performs a different job. Its denser construction is intended to create separation and protection between the spring system and upholstery layers above.

Spring Insulator for Double Cone Springs

Traditional upholstered furniture often uses individual coil springs positioned and secured within the furniture frame.

Status Fabrics' Double Cone Springs are traditional hourglass-style upholstery springs commonly associated with hand-built and restored furniture.

Once a traditional spring foundation has been correctly installed and secured, a spring insulation layer can be positioned above it before the subsequent upholstery padding is added.

This helps create separation between the coil springs and the fillings above while providing a more continuous upholstery surface.

Spring Insulator for ZigZag and Sinuous Springs

Modern sofas and chairs frequently use ZigZag Springs, also known as sinuous, serpentine or no-sag springs.

These springs span the furniture frame and create a flexible seat or back foundation.

A compressed polyester spring insulator can be used above a suitable zigzag spring system to create a protective layer between the curved spring wires and subsequent upholstery materials.

Status Fabrics' zigzag spring range is commonly used for sofa and chair seat support and includes different lengths and gauges for compatible furniture constructions.

Using Spring Insulation Over Spring Units

Pre-assembled Spring Units provide a connected spring foundation for suitable chairs, sofas and other upholstered seating.

Where the furniture construction requires an insulation layer above the spring unit, compressed polyester provides a practical barrier before the main padding or cushioning materials are installed.

The exact upholstery build-up will depend on the furniture design and the original construction, so restoration work should normally follow the existing layering system unless the furniture is being professionally redesigned.

Which Upholstery Spring System Do I Need?

Double cone springs are commonly used in traditional hand-built and restoration work.

Zigzag springs, also known as sinuous or serpentine springs, are widely used in modern sofa and chair frames.

Spring units provide a pre-assembled spring foundation where a complete connected system is required.

see the Upholstery Springs range to compare spring types, fixing components and related furniture-support products.

When repairing existing furniture, retaining the original type of spring system is generally the most straightforward approach unless the frame and upholstery construction are being professionally redesigned.

Where Does the Spring Insulator Sit in the Upholstery?

The exact layering varies between furniture constructions, but the spring insulator is normally positioned directly above the completed spring foundation.

A typical sprung upholstery construction may include:

Furniture frame spring system spring insulator felt or padding foam or other cushioning upholstery fabric

Not every sofa or chair uses exactly the same construction, so existing furniture should be inspected carefully before dismantling.

Photographing the original upholstery layers as they are removed can provide a useful reference when rebuilding the furniture.

Spring Insulator for Furniture Repair and Manufacture

This 300g compressed polyester spring insulation is suitable for professional upholsterers, furniture manufacturers, repair workshops and experienced customers restoring sprung furniture.

The 40" width provides useful coverage across many chair and sofa frames, while the 30 metre roll is practical for workshop use and repeated furniture repairs.

300g compressed polyester spring insulator for creating a durable protective layer between upholstery springs and the foam, felt or other filling materials above.

• 40" wide
• 30 metre roll
• 300g compressed polyester
• Approx. 12mm thick
• Creates a protective barrier over upholstery spring systems
• Suitable for sofas, chairs, seating and furniture restoration
• Useful over double cone springs, zigzag springs and compatible sprung units

The compressed polyester layer helps prevent upholstery fillings from pressing directly into or between the springs and provides a more even surface for the layers above.

Suitable for use with Double Cone Springs, ZigZag Springs and compatible Spring Units.
