White 50gsm Corovin for Cushion Linings and Foam Reinforcement

The White 50gsm Dipryl and Corovin – 150cm Wide is a lightweight spunbond upholstery material.

It is:

• White
• Approximately 50gsm
• 150cm wide
• Available by the metre
• Available as a 100-metre roll

Unlike black base cloth, this white Corovin is commonly used for manufacturing inner cushion cases and reinforcing selected foam components.

Potential applications include:

• Inner cases for fibre-filled cushions
• Scatter-cushion liners
• Back-cushion interiors
• Wrapping suitable loose fillings
• Reinforcing foam platforms
• Reinforcing upholstered arms
• Lightweight furniture lining
• Cushion-manufacturing work

The white colour also makes markings, seams and contamination easier to see during cushion production.

White Corovin for Fibre Cushion Cases

White Dipryl can be sewn into a lightweight inner case for containing suitable loose fibre fillings.

It may be used for:

• Scatter cushions
• Fibre back cushions
• Decorative cushion interiors
• Bolster fillings
• Loose furniture cushions

The inner case helps contain the filling and separates it from the decorative outer cover.

When making an inner cushion case:

1. Prepare an accurate pattern.
2. Include suitable seam allowances.
3. Cut matching panels.
4. Use appropriate sewing thread and stitch length.
5. Leave a controlled filling opening.
6. Add the fibre gradually.
7. Distribute the filling evenly.
8. Close the opening securely.
9. Check the completed shape.
10. Fit it into the outer cover.

Browse Fibre and Feather Cushions for associated cushion interiors and fillings.

White Corovin Laminated to Foam

White Corovin may also be laminated or bonded to suitable foam to provide reinforcement on foam platforms, arms and shaped upholstery components.

The Corovin layer can help:

• Support the foam surface
• Reduce localised tearing
• Provide a cleaner handling surface
• Hold shaped foam sections together
• Reinforce selected manufactured components

Use only an adhesive that is compatible with both the Corovin and the selected foam.

Browse Upholstery Adhesives and Aerosols for suitable bonding products.

Test the adhesive first, as excessive application may soak through the lightweight fabric or damage the foam.

Black Corovin and Dipryl Furniture Base Cloth

The Black Dipryl and Corovin Upholstery Base Cloth is a strong spunbond material widely used to complete the underside and rear of upholstered furniture.

Available options include:

• 70gsm standard weight
• 100gsm heavier weight
• 100cm width
• 150cm width
• Material by the metre
• 100-metre rolls

Potential applications include:

• Sofa undersides
• Armchair bases
• Dining-chair seat pads
• Footstools
• Headboard backs
• Bed bases
• Furniture backs
• Upholstered panels
• General furniture manufacturing

The black colour provides a discreet professional appearance and helps conceal the internal structure of the furniture.

Standard 70gsm Black Corovin

The 70gsm version provides a practical standard-weight base cloth for general upholstery work.

Choose it where:

• A lightweight underside covering is required
• The cloth will mainly provide concealment
• It will be fitted to sofas, chairs or headboards
• Easy cutting and stapling are priorities
• A cost-effective production fabric is needed

It is suitable for many domestic furniture repairs and routine workshop applications.

Heavier 100gsm Black Corovin

The 100gsm option is thicker and stronger than the standard 70gsm material.

Choose the heavier grade where:

• A more substantial lining is preferred
• The furniture base will receive more handling
• Additional resistance to accidental tearing is useful
• The cloth will be used on larger furniture
• A heavier professional underside finish is required

The heavier material remains a lining and dust-cover cloth rather than a structural support for springs, webbing or seat fillings.

Choosing 100cm or 150cm Width

Choose 100cm-wide Corovin for suitable:

• Dining-chair pads
• Narrow armchairs
• Footstools
• Headboards
• Smaller furniture bases

Choose 150cm-wide Corovin for:

• Sofas
• Broad chairs
• Beds and divans
• Larger headboards
• Wide upholstered panels
• Projects where fewer joins are preferred

Measure the complete outer dimensions of the furniture base and allow enough material for gripping, tensioning and stapling beyond the visible opening.

Woven Polypropylene Furniture Base Cloth

The 100cm-Wide Woven Polypropylene Upholstery Base Cloth is a woven alternative to non-woven Dipryl or Corovin.

It is:

• 100cm wide
• Woven polypropylene
• Available by the metre
• Available as a 100-metre roll

It is commonly fitted to the bottoms of sofas and chairs to create a professional finish and help protect the furniture interior from dust.

Potential applications include:

• Sofa bases
• Armchair undersides
• Dining-chair pads
• Footstools
• Upholstered benches
• Bed and headboard backs
• Furniture-manufacturing projects

Woven Polypropylene or Corovin?

Choose woven polypropylene where:

• A woven material is preferred
• A 100cm width suits the furniture
• A more defined woven structure is required
• The fabric will be used principally beneath sofas or chairs

Choose Corovin where:

• A lightweight spunbond fabric is preferred
• A 150cm-wide option is required
• A choice between 50gsm, 70gsm and 100gsm is useful
• White material is needed for cushion liners or foam reinforcement
• Rapid cutting and production handling are priorities

Both materials are primarily intended as furniture lining and dust-cover fabrics.

What Is Corovin?

Corovin is a synthetic spunbond material used throughout upholstery and furniture manufacturing.

Its structure provides a lightweight fabric that is:

• Easy to cut
• Straightforward to staple
• Suitable for sewing in appropriate applications
• Suitable for compatible adhesive bonding
• Resistant to excessive edge fraying
• Economical for production work

Corovin is often called Dipryl within the upholstery industry.

The names Corovin, Dipryl, spunbond base cloth and sofa bottom cloth are commonly used for similar lightweight synthetic furniture linings.

What Is Upholstery Base Cloth Used For?

Base cloth is normally fitted as one of the final stages of furniture production or reupholstery.

It helps:

• Conceal internal upholstery components
• Reduce dust entering the furniture
• Contain loose fibres and debris
• Cover springs and webbing from below
• Provide a clean underside
• Improve the finished appearance
• Protect the interior during handling and delivery

It may also be fitted to furniture backs where the rear surface faces a wall and does not require the main decorative covering.

Base Cloth or Platform Cloth?

Base cloth and platform cloth perform different jobs.

Choose base cloth or Corovin where:

• The material covers the underside of furniture
• It will not normally be seen during use
• Its main purposes are concealment and dust protection
• A lightweight fabric is sufficient

Choose Upholstery Platform and Lining Cloth where:

• The material sits directly beneath removable cushions
• It may be visible when cushions are removed
• A stronger woven furniture fabric is required
• The material will receive regular contact and friction

Corovin should not automatically be used in place of a load-bearing platform cloth.

Base Cloth or Needle-Punch Fabric?

Choose Corovin where:

• A lightweight base fabric is preferred
• The furniture requires an economical underside cover
• Fast cutting and stapling are important
• A 100-metre production roll is useful

Choose Needle-Punch Upholstery Fabric where:

• A heavier non-woven fabric is preferred
• A felt-like surface is required
• The material will be used on furniture backs or internal panels
• Automotive, campervan or general trim work is planned

Measuring Furniture for Base Cloth

Before ordering:

1. Turn the furniture over safely.
2. Measure the full outer length of the base.
3. Measure the full outer width.
4. Include any projecting rails or shaped areas.
5. Allow material beyond every fixing line.
6. Check whether the selected roll width will cover the base in one piece.
7. Plan any unavoidable joins.
8. Include additional material for cutting waste.
9. Add other chairs, stools or headboards.
10. Allow spare material for later repairs.

The internal frame opening is usually smaller than the piece of base cloth required.

Allow enough material to grip and tension the fabric without placing staples too close to the cut edge.

Choosing Material by the Metre or Full Roll

Order by the metre where:

• One item of furniture is being repaired
• Only a small quantity is required
• Several different cloths are being tested
• Workshop storage is limited

Choose a 100-metre roll where:

• Furniture is manufactured regularly
• A workshop frequently replaces base cloth
• Several matching pieces are being completed
• Trade production requires a continuous supply
• Reducing repeated small orders is useful

Store full rolls clean, dry and protected from crushing or contamination.

Preparing Furniture Before Fitting Base Cloth

Base cloth should be installed after the underlying furniture has been inspected and repaired.

Before fitting, check:

• Timber-frame joints
• Springs
• Webbing
• Clips and wires
• Foam
• Loose fibres
• Old staples
• Sharp edges
• Protruding screws or nails
• Evidence of contamination or pests

Remove loose debris and replace damaged internal components before concealing the base.

Browse Upholstery Springs and Webbing for replacement suspension materials.

Base cloth should provide the final professional finish rather than hide unresolved structural problems.

Removing Old Furniture Base Cloth

To replace damaged bottoming cloth:

1. Photograph the original fixing arrangement.
2. Turn the furniture over securely.
3. Remove loose staples or tacks.
4. Lift away the old cloth.
5. Avoid damaging the timber rails.
6. Remove remaining fragments.
7. Inspect the frame and upholstery.
8. Complete any necessary repairs.
9. Clean away dust and debris.
10. Measure for the replacement cloth.

Browse Staple Removers, Tack Lifters and Ripping Chisels for suitable removal tools.

Wear gloves and eye protection, as old staples and spring ends may be sharp.

Cutting Corovin and Base Cloth

Use sharp Upholstery Shears and Cutting Tools.

Before cutting:

• Lay the material flat
• Check the width
• Mark the required dimensions
• Include fixing allowances
• Keep the cut square
• Avoid contaminating white Corovin
• Label pieces for matching furniture
• Keep the material away from adhesive overspray

Corovin does not generally require the same large fraying allowance as loosely woven hessian, but sufficient fabric must remain beyond the staple line.

Fitting Base Cloth with Upholstery Staples

Base cloth is commonly fixed with upholstery staples.

Browse:

• Upholstery Staples
• Pneumatic Upholstery Guns and Tackers

A practical fitting sequence is:

1. Position the cloth over the complete base.
2. Align it squarely with the furniture.
3. Place a temporary staple at the centre of one side.
4. Apply light tension to the opposite side.
5. Fix the remaining two centres.
6. Work gradually towards each corner.
7. Keep the tension even.
8. Fold or trim the corners neatly.
9. Complete the staple line.
10. Remove excessive material.

Base cloth should be smooth and tidy without being stretched so tightly that it tears around the staples.

Fitting Base Cloth Around Furniture Legs and Mechanisms

Some furniture bases include:

• Legs
• Castor sockets
• Recliner mechanisms
• Electrical cables
• Hinges
• Bed actions
• Moving linkages
• Ventilation openings

Cut and fit the cloth so it does not interfere with moving parts, electrical equipment or access points.

Where future servicing may be required, consider:

• Removable panels
• Hook-and-loop closures
• Clearly positioned access openings
• Separate base-cloth sections

Do not staple through cables or close to moving mechanisms.

Sewing and Bonding Corovin

Corovin may be sewn or bonded in suitable manufacturing applications.

White Corovin is particularly useful for lightweight cushion liners and fabricated foam components.

When sewing:

• Use suitable thread
• Select an appropriate needle
• Avoid excessively short stitches
• Prepare a test seam
• Check that the fabric does not tear under tension

When bonding:

• Use an adhesive compatible with polypropylene or spunbond fabric
• Test for strike-through
• Apply a controlled quantity
• Protect visible furniture surfaces
• Allow the bond to cure fully

Care and Inspection

Base cloth normally requires little routine maintenance, but it should be inspected if the furniture is moved or turned over.

Check for:

• Tears
• Loose staples
• Sagging
• Open edges
• Damage around legs
• Dust or debris escaping
• Contact with springs or mechanisms
• Signs of damp or contamination

Small tears may require patching, while extensive or brittle material is normally better replaced.

Fire Safety and Upholstery Compliance

Corovin and woven polypropylene base cloth should not automatically be treated as upholstery fire-barrier fabrics.

Where a fire-resistant interliner is required, browse Calico, Cambric and Crib 5 Upholstery Interliners.

The fire performance of completed furniture depends on its full construction, including:

• Cover fabric
• Foam
• Fillings
• Interliners
• Platform materials
• Sewing thread
• Adhesives
• Upholstery method
• Permanent fire labels

Select each material according to the intended domestic or contract use.
