Use it for Deep Sofa and Armchair Restoration

The 25" mesh top spring units are suitable for furniture originally designed around a deeper spring foundation.

Typical applications include:

• Deep-seated traditional sofas and settees.
• Large upholstered armchairs.
• Two-seater and three-seater sofa restoration.
• Replacement of worn or damaged spring assemblies.
• New furniture manufacture.
• Professional upholstery refurbishment.

Before purchasing, check the available internal dimensions, existing fixing arrangement and condition of the timber frame.

Recommended Upholstery Padding and Fillings

A mesh top spring unit provides the underlying support, but suitable upholstery padding is required to create a comfortable finished seat.

Needled Felt Platform Padding

Provides a firm, structured padding layer above a suitable spring foundation, helping create an even surface and protect the upholstery fillings.

Rubberised Coir Fibre Sheet

A resilient natural coir fibre sheet bonded with rubber, suitable for building supportive padding layers within traditional upholstery.

Ginger Coir Fibre

Loose natural coconut fibre used for stuffing, shaping and rebuilding traditional upholstery profiles.

Select padding according to the original furniture construction and required finished seat.

Hessian, Platform Cloth and Upholstery Fixings

Upholstery Hessian is commonly used to cover spring foundations and provide a supporting layer beneath traditional fillings.

Platform & Lining Cloths provide a smooth, tidy finished surface beneath removable sofa and chair cushions.

When attaching suitable fabrics and covering materials to timber frames, see Upholstery Staples and Staple Guns & Tackers.

Ensure staples are compatible with the selected gun and timber. The spring unit itself must be secured using the correct fixings for its construction.

Choosing Between 22" and 25" Spring Units

22" Deep Mesh Top Spring Unit

made for compatible furniture frames requiring a shallower spring foundation.

25" Deep Mesh Top Spring Unit

Provides an additional 3" of front-to-back depth for furniture with a larger internal seating frame.

Both ranges share the same chair, two-seater and three-seater widths and tapered heights.

A deeper spring unit is not automatically more comfortable. The correct choice depends on the original furniture construction and available frame dimensions.

Measuring Before Ordering

Measure the clear internal frame depth, front width and rear width, allowing for fixing rails, corner blocks and any centre supports.

Check the available front and rear heights and ensure the spring unit will not interfere with existing furniture mechanisms or structural components.

Where possible, compare the measurements against the original spring assembly.
