The Raw-Edges chair removes adhesives, staples, and mechanical fasteners by relying on a carved wooden frame and friction-based assembly. The design features a continuous groove cut into the frame, allowing the upholstered foam cushion to be inserted and secured through pressure alone. This method replaces conventional upholstery techniques that typically require glue, tacks, or staples to keep materials in place.
The chair was developed by Raw-Edges Design Studio in collaboration with Italian furniture brand Bolzan. Its construction allows the cushion to be removed without tools, separating soft and rigid components for maintenance or replacement. The frame is precision-cut to ensure a tight fit between materials, with stability achieved through contact and compression. The project remains in development, with the construction method defining how the parts are assembled and held together.

Trend Themes
1. Friction-based Assembly - Precision-cut joinery enabling secure, adhesive-free connections across dissimilar materials presents opportunities to simplify production and reduce chemical use.
2. Modular-replaceable Cushions - Removable soft components that separate from rigid frames create possibilities for independent lifecycle management and tailored refurbishment pathways.
3. Tool-free Maintenance - Assemblies designed for disassembly without tools offer potential for rapid on-site servicing and extended product longevity.
Industry Implications
1. Furniture Manufacturing - Upholstered furniture producers could adopt adhesive-free construction methods to lower VOC emissions, streamline assembly lines, and simplify end-of-life recycling.
2. Automotive Interiors - Vehicle seating and interior panel makers may integrate friction-fit soft elements to facilitate repairability and material recovery while meeting safety and comfort requirements.
3. Healthcare and Contract Seating - Hospitals and commercial seating suppliers might leverage separable cushions to support stringent hygiene protocols and targeted part replacement without discarding entire units.
