For interior designers and specifiers, upholstery is often one of the final elements that brings a project together.
Whether it is a window seat, banquette, or loose cushions, the quality of the upholstery work has a direct impact on both the look and long-term performance of the space.
This guide outlines how to approach custom upholstery in New Zealand, what to consider when specifying materials, and how to work effectively with a supplier.
What falls under custom upholstery?
Custom upholstery typically includes made-to-measure pieces designed specifically for a project.
- window seat cushions and squabs
- bench and banquette seating
- loose seat and back cushions
- reupholstery of existing furniture
- commercial seating for hospitality or office environments
Each project is different, which is why custom work is often preferred over off-the-shelf solutions.
When to specify custom upholstery
Custom upholstery is most relevant when:
- dimensions are non-standard or built-in
- fabric selection needs to match a wider scheme
- durability requirements are higher for commercial or high-use spaces
- the design calls for a tailored or architectural finish
For many residential and commercial projects, it becomes the only option that delivers both fit and finish.
Key considerations when specifying
Foam and comfort
Foam selection should be based on how the seating will be used.
- softer foams suit occasional or decorative seating
- medium to firm foams are better for daily use
- high-density foams are required for commercial applications
Comfort, longevity, and structure all depend on getting this right early in the process.
Fabric selection and durability
Fabric is not just a visual decision.
Designers should consider:
- durability, including Martindale rating where applicable
- cleanability and maintenance
- light exposure and fading
- suitability for indoor versus outdoor use
For commercial projects, performance fabrics are often essential. For residential projects, there is usually more flexibility, but durability should still align with how the space is used.
Fit and construction
Accurate measurement is critical, especially for built-in seating.
- tolerance within joinery
- cushion thickness and proportions
- edge detailing such as piping or boxed edges
- removable versus fixed covers
Small decisions here make a significant difference to the final result.
Indoor versus outdoor applications
Outdoor cushions require completely different materials.
- quick-dry or outdoor foam
- weather-resistant fabrics
- breathable construction to prevent moisture retention
Using indoor materials outside will lead to early failure.
Working with an upholstery supplier
A good supplier should support the design process, not just execute it.
A typical workflow includes:
- initial brief and measurements
- material and foam selection
- quoting and confirmation
- production
- delivery or installation
Clear communication early on helps avoid delays later in the project.
Lead times and planning
Custom upholstery is usually one of the final stages of a project, but it should be planned earlier.
Lead times can vary depending on project size, material availability, and level of customisation. Allowing sufficient time ensures cushions are ready when joinery and installation are complete.
Residential versus commercial projects
While the process is similar, the requirements differ.
Residential
- more flexibility in materials
- focus on comfort and aesthetics
Commercial
- stricter durability requirements
- higher wear and tear
- often requires performance-rated fabrics and foams
Understanding this distinction is important when specifying.
Common issues to avoid
Some of the most common problems in upholstery projects come from:
- incorrect measurements
- choosing foam that is unsuitable for the use
- using fabric that is not appropriate for the environment
- leaving decisions too late in the project timeline
Addressing these early leads to a smoother outcome.
Final thoughts
Custom upholstery is one of the details that can elevate a project when done well.
For designers, working with the right supplier ensures that both the aesthetic and practical aspects are considered from the beginning.
Whether the project is residential or commercial, taking a structured approach to materials, sizing, and construction leads to a better long-term result.
