Proto Chair In by Plus Halle is the indoor lounge chair variant in Nick Ross's Proto series — a lounge chair whose material character is rooted in the same design philosophy that runs through the entire Proto collection: fabrication process and material trace preserved as part of the finished object rather than resolved away in pursuit of a conventional upholstered or polished chair finish. The Chair In's form provides proper lounge seating — a seat, back and arm structure proportioned for relaxed sitting in an indoor environment — while the surface treatments and material choices retain the raw, process-honest character that makes the Proto series immediately distinctive within Plus Halle's broader range.

The Proto Chair In is designed for indoor use and is appropriate in the lounge and reception environments where the wider Proto collection is typically specified: design-forward hotel lobby areas, creative studio and co-working social spaces, cultural institution common areas, boutique hospitality environments and residential living rooms where a lounge chair of individual material character and genuine design provenance is the specification intent. It works most coherently alongside the other Proto series pieces — the Proto coffee tables, side table, bench and pouf — creating a complete lounge environment from a single designer's resolved material vocabulary. The indoor material specification ensures the chair's surface treatments are calibrated for the light, temperature-stable conditions of an interior environment.

Interior designers and architects specifying the Proto Chair In for indoor lounge environments will find the 3D model and Revit family useful for BIM-accurate furniture placement and spatial coordination across hospitality, commercial and residential project models. A considered and materially distinctive lounge chair specification for any project deploying the Proto series in indoor settings.
