Trade and wholesale foam for interior design and contract furniture projects should be specified alongside the furniture construction, fire requirement, dimensions, expected use and project documentation. Choosing the foam after the design is already fixed can create avoidable compromises in seat depth, comfort, clearances and compliance.
Quick answer
Interior designers should define the finished use, seat or panel depth, required feel, dimensions, project fire specification, quantity and visual or technical constraints before selecting foam. For contract work, do not assume a domestic seating grade automatically satisfies the client's specification.
Bring foam into the design process early
Foam affects more than comfort.
It can influence:
- finished seat height
- cushion proportions
- cover tension
- edge appearance
- bench depth
- headboard thickness
- joinery clearances
- acoustic panel depth
- mattress height
- storage and access around removable components
A late material change can alter the final look and feel of the design.
Separate domestic and contract requirements
An upholstered chair in a private home and a banquette in a public venue may have different project requirements.
Domestic upholstered furniture is subject to the relevant UK furniture fire-safety regulations. Designers and suppliers should check the current UK government furniture fire-safety guidance. Contract and commercial projects can also specify additional standards or client requirements.
The design team should record the applicable requirement in the project specification rather than simply writing "fire-retardant foam".
When fire performance matters, check the exact All Foam product data and relevant technical data sheet.
Specify the component, not just the room
A restaurant fit-out might contain several foam requirements:
- banquette seats
- loose back cushions
- upholstered wall panels
- decorative headboards
- acoustic treatment
- staff seating
- custom mattresses in accommodation areas
Each should have its own component reference.
This avoids one generic foam specification being copied across items with different functions.
Plan seating around the support system
The same foam can feel different depending on what is underneath it.
Consider:
- solid board
- webbing
- springs
- slatted support
- cushion depth
- cover tension
- seat angle
Designers should approve a mock-up in the actual construction when comfort is important.
For trade seating, the furniture manufacturer foam guide explains how to build a repeatable component schedule.
Use the current upholstery range by application
The All Foam upholstery foam sheet range provides multiple grades so designers can balance comfort, support and available depth.
Avoid specifying solely by colour.
Write the approved product name or performance requirement in the schedule.
If a design uses a very thin seat, it may require different support from a deep sofa cushion even when the visual brief describes both as "medium-firm".
Custom furniture needs dimension control
Bespoke joinery and upholstery often leave little tolerance for late dimensional changes.
For each foam component, record:
- length
- width
- thickness
- shape
- orientation
- cover allowance
- support beneath it
- finished seat height
- drawing revision
If the component is non-rectangular, confirm the required fabrication route before the design is issued for production.
Read the custom foam fabrication guide for drawing and tolerance guidance.
Acoustic foam is a separate design decision
Interior projects may also include acoustic treatment.
Acoustic foam is used to manage reflections and reverberation. It is not a structural soundproofing layer.
Where a project specifically requires Class 0 acoustic foam, the current All Foam AFPCLS0 range is supplied as flat unbacked 25mm and 50mm sheets. The relevant fire classification and technical information should be checked against the project requirement.
See the Class 0 acoustic foam range.
Plan repeat furniture across multiple sites
Hospitality, retail and accommodation projects often repeat furniture across rooms or locations.
Create a schedule that records:
- furniture type
- foam component
- exact grade
- dimensions
- quantity per furniture item
- quantity per site
- fire requirement
- revision
- supplier product reference
This helps avoid small variations being introduced between sites.
Consider replacement and maintenance
A good design also considers how the foam will be replaced later.
Questions include:
- can the cushion be removed?
- is the foam accessible without dismantling joinery?
- are dimensions recorded?
- can the same grade be identified later?
- does the cover have enough access for replacement?
- is the component likely to receive heavy use?
Recording the specification now can make refurbishment easier years later.
Trade pricing should follow the specification
Do not reduce the project to "What is your trade discount?"
A commercial quote is more useful when the supplier knows the actual grade, component sizes, quantities and order pattern.
All Foam reviews trade requirements individually rather than publishing one fixed wholesale percentage.
Read trade discounts on foam sheets for the factors that can affect a quote.
What should an interior designer send with an enquiry?
Send:
- project type
- furniture or component description
- foam grade if already approved
- required feel or performance
- finished dimensions
- quantity
- drawing or schedule
- fire or technical requirement
- delivery postcode
- required date
- whether the project repeats across sites
Quick answer: what is the best way to specify foam?
Treat foam as a named component in the project schedule. Record the exact product or approved performance, finished dimensions, quantity and fire requirement. Then test the material in the real furniture construction before releasing a large production order.
