Full description and care

Replacement Fibre Filled Seat Cushions

The made to measure fibre filled seat cushions are made for replacing flat, tired, sagging or uncomfortable sofa and chair cushion interiors.

They are suitable for customers who want a soft, plump and feather-free cushion filling for sofas, chairs, armchairs, loose seat pads and traditional upholstery cushions.

If your existing sofa seat cushions have become flat, hollow, lumpy or uncomfortable, replacing the interior can help restore fullness and comfort while allowing you to retain the original cushion cover.

Fibre filled seat cushions give a softer and more relaxed feel than foam and are best suited where comfort and fullness are more important than firm support or sharp shape retention.

Made to Measure Fibre Seat Cushion Interiors

Each fibre cushion interior is quoted and made to order according to the cushion size, shape and required fullness.

We can supply replacement fibre cushion inners for:

  • Square seat cushions
  • Rectangular seat cushions
  • T-shaped cushions
  • L-shaped cushions
  • Tapered cushions
  • Curved cushions
  • Rounded-corner cushions
  • Loose chair cushions
  • Armchair cushions
  • Traditional upholstery seat cushions

For unusual or complex shapes, contact us with a clear photograph of the empty cushion cover.

Replacing Flat or Sagging Sofa Seat Cushions

Seat cushions take regular daily use and soft fillings naturally settle over time.

Common signs that a replacement interior may be needed include:

  • Flat sofa seat cushions
  • Sagging or collapsed filling
  • Uneven or lumpy cushions
  • Cushions that no longer recover after plumping
  • Loose-looking covers
  • Seats that have lost their original fullness

A new replacement fibre seat cushion inner can improve the appearance and comfort of the furniture without replacing an otherwise serviceable sofa or chair.

Fibre Chair and Armchair Seat Cushions

Fibre is also suitable for many chair and armchair applications where a softer, more relaxed seat is preferred.

Typical uses include:

  • Armchair cushions
  • Fireside chairs
  • Occasional chairs
  • Loose chair pads
  • Traditional furniture
  • Light-use seating
  • Furniture restoration projects

Fibre is lighter and softer than foam and produces a fuller, more relaxed cushion appearance.

Feather-Free Seat Cushion Filling

Fibre is a useful option for customers looking for a feather-free cushion interior.

It provides softness, fullness and comfort without feather or down and can be used for sofa cushions, chair cushions and armchair seats where a softer filling is wanted.

Please note that feather-free does not automatically mean allergy-free. Customers with specific allergy requirements should check suitability before ordering.

Fibre Seat Cushions vs Feather Seat Cushions

Both fibre and feather create soft, relaxed seat cushions, but they feel and behave differently.

Fibre seat cushions are:

  • Lighter
  • Feather-free
  • Soft and plump
  • Easier to handle
  • Often fuller in appearance

Feather seat cushions are:

  • Heavier
  • More traditional
  • It is naturally mobile
  • Softer with a classic upholstered feel
  • Designed to be regularly dressed and plumped

If you prefer a traditional natural filling, see the Feather Seat Cushions.

Fibre Seat Cushions vs Foam Seat Cushions

Fibre and foam provide very different levels of support.

Fibre is soft, lightweight and relaxed. It works best where a plump seat cushion and softer feel are the priority.

Foam is firmer, more supportive and holds its shape more consistently.

For heavily used everyday sofa seats, foam or a foam core with a soft wrap may often be the better choice where stronger support and lower maintenance are required.

For firmer alternatives, explore Foam Cut to Size.

How to Measure for Replacement Fibre Seat Cushions

For the best result, measure the empty cushion cover, not the old cushion filling.

Older fibre interiors can flatten, spread and distort, so measuring the existing inner may give inaccurate dimensions.

Step 1: Remove the Existing Cushion Interior

Remove the old fibre, feather or foam filling completely from the cover.

Step 2: Measure the Width

Measure from seam to seam across the front of the empty cushion cover.

Step 3: Measure the Depth

Measure from the front seam to the back seam.

Step 4: Measure the Border

If the cushion has a boxed edge, measure the border panel from seam to seam.

This helps us assess the amount of filling required and the appropriate finished fullness.

Step 5: Check the Cushion Shape

Tell us whether the cushion is square, rectangular, T-shaped, L-shaped, tapered, curved, rounded or another shape.

For complex cushions, photographs or a paper template may be required.

Why Fibre Seat Cushions Are Quoted to Order

Fibre cushion interiors are not a one-size-fits-all product.

The amount of filling required depends on:

  • Cushion size
  • Cushion shape
  • Border depth
  • Cover construction
  • Fabric type
  • Required fullness
  • Intended use

For this reason, fibre filled seat cushions are individually quoted rather than treated as a standard cushion pad.

Important Fibre Cushion Care

Fibre cushions are soft and comfortable, but they do need regular care.

We recommend:

  • Daily plumping
  • Turning
  • Dressing
  • Redistributing the filling

Fibre naturally settles during use. Regular care helps keep the filling evenly distributed and maintains the cushion's fullness and appearance.

Unlike foam, fibre will not hold a fixed shape permanently.

Matching Fibre Back Cushions

If you are replacing seat interiors, it may also be worth checking the condition of the back cushions.

The Fibre Back Cushions provide made to measure feather-free replacement interiors for sofas, chairs and armchairs.
