RX36/110 White Foam Sheet
RX36/110 White Foam Sheet is a very soft seating-quality upholstery foam, particularly useful for replacing tired or collapsed fibre and feather cushion interiors where a softer, fuller-looking finished cushion is required.

Soft Foam for Replacing Fibre & Feather Cushions
One of the main uses for RX36/110 is replacing collapsed, tired or uncomfortable fibre and feather cushion interiors.
Traditional fibre and feather cushions can provide a very soft feel and full appearance, but customers sometimes decide they would prefer to replace the existing filling with a foam interior while retaining a softer cushion feel.
RX36/110 is particularly suited to this type of refurbishment because its very soft specification allows a foam cushion to achieve a softer feel than many conventional seating grades.
It can be especially useful for:
- Sofa seat cushions
- Armchair cushions
- Loose cushions
- Replacement cushion interiors
- Furniture refurbishment
- Cushions originally designed around softer fillings
Wrapping the foam with Polyester Wadding can help create a softer edge and fuller finished appearance beneath the existing cushion cover.
A Roll of Stockinette can then be fitted over the foam or wadding-wrapped interior to reduce friction and make fitting into a close-fitting upholstery cover easier.
If you would prefer to retain a traditional soft filling rather than convert the cushion to foam, browse our Fibre & Feather Cushions for alternative replacement cushion interiors.
A Fuller-Looking Replacement Foam Cushion
RX36/110 is particularly useful when replacing a soft cushion where maintaining a full, rounded upholstered appearance is important.
The foam core provides the basic shape of the cushion while polyester wadding can be added around the foam to increase loft and soften the finished edges.
For this type of cushion construction, we recommend considering:
Polyester Wadding – for wrapping the foam and creating a softer, fuller cushion profile.
Roll Stockinette – fitted over the finished cushion interior to make inserting it into the upholstery cover easier.
The thickness of the wadding required will depend on the existing cover, the desired finished appearance and how much additional loft is needed.
If you are replacing an existing cushion and are unsure about the correct foam dimensions or construction, please contact Livedale before ordering.
RX36/110 for Soft Back Cushions
RX36/110 is also a popular choice for sofa and chair back cushions where a softer feel is required.
Back cushions generally carry less direct body weight than seat cushions and often benefit from a softer, more forgiving foam.
Typical applications include:
- Loose sofa back cushions
- Armchair back cushions
- Fixed furniture backs
- Soft upholstered backs
- Replacement back cushion interiors
For an even fuller finished cushion, RX36/110 can be wrapped with Polyester Wadding before the final cover is fitted.
Where the customer specifically wants a traditional fibre or feather-filled back cushion rather than foam, our Fibre & Feather Cushions provide an alternative option.
RX36/110 as a Comfort Layer Over Firmer Foam
Another important use for RX36/110 is as a soft comfort layer over a firmer supporting foam base.
Layered foam construction allows different foam grades to perform different jobs within the same cushion.
The firmer lower layer provides support, while the softer RX36/110 upper layer creates a more forgiving surface.
This type of construction can be useful for:
- Sofa cushions
- Bespoke seating
- Contract furniture
- Bench seating
- Banquette seating
- Specialist cushion constructions
- Furniture refurbishment
Where an especially firm supporting layer is required, RX36/110 can be combined with Reconstituted Foam Sheet.
Suitable foam layers can be bonded using Livedale Heavy Duty Spray Adhesive 500ml where appropriate.
The correct combination of foam grades and thicknesses will depend on the application, so please contact Livedale if you need help deciding on a layered foam construction.
Is RX36/110 Suitable for Seat Cushions?
Yes. RX36/110 is a very soft seating-quality foam and can be used for seat cushions where a deliberately softer feel is required.
It is particularly relevant when replacing cushions that were originally filled with fibre or feather and where using a conventional firm seating foam could significantly change the character of the furniture.
However, RX36/110 will feel considerably softer than grades such as RX33/190 or other firmer seating foams.
If your priority is firm support rather than a soft, fuller cushion, browse our complete Foam Sheets range or contact Livedale for advice.
Foam or Fibre & Feather?
The right replacement depends on the finished feel and appearance you want.
Choose RX36/110 foam when you want:
- A very soft foam cushion
- A shaped foam core
- A replacement for a collapsed soft cushion
- A foam interior that can be wrapped for additional fullness
- A soft comfort layer over firmer foam
If you want to retain a more traditional loose-filled cushion construction, explore our Fibre & Feather Cushions instead.
If you are uncertain which route is best for an existing sofa or chair, contact Livedale and we can discuss the cushion construction before you order.
Complete Your Replacement Cushion
Customers using RX36/110 for replacement cushion interiors will often also need the materials required to produce the finished cushion.
Polyester Wadding – wraps around the foam to soften the edges, add loft and create a fuller upholstered appearance.
Roll Stockinette – fits over foam or wadding-wrapped cushion interiors to reduce friction and make fitting into close upholstery covers easier.
Reconstituted Foam Sheet – provides a very firm supporting base when RX36/110 is being used as the softer upper layer of a layered cushion.
Livedale Heavy Duty Spray Adhesive 500ml – useful for suitable foam-to-foam bonding and layered upholstery constructions.
