Product Description

The Fixed Auditorium Chair with Retractable Writing Tablet, model AUD-RED-001, is a purpose-built public seating solution delivered as unbranded auditorium seating, engineered to support consistent high-traffic use across formal public gathering spaces. Its visual profile presents a streamlined, structured silhouette suited to orderly row layouts, with smoothly contoured upholstered seat and back surfaces, warm stained solid beech wood armrests, and a slender matte-finish die-cast aluminum support pedestal that creates an open, uncluttered sightline for venue audiences. The side-mounted retractable writing tablet sits flush with the armrest assembly when folded, preserving clean, uniform row aesthetics when not in use. Overall dimensions measure 620 x 680 x 1020 mm, with 540 mm of clear width between armrests, a 90 mm thick seat cushion, 70 mm thick padded backrest, and a 240 mm tall dedicated lumbar support zone, all balanced to deliver consistent postural support for extended sitting periods. Construction prioritizes long-term durability through a layered material specification: seat and back surfaces are wrapped in woven polyester fabric with a stain-resistant finish, padded with high-resilience polyurethane foam at 45 kg/m³ density for the seat (with 65% rebound performance) and 35 kg/m³ density for the back. Structural components include a 1.8mm thick cold-rolled steel inner seat frame, zinc-plated steel hinge hardware, powder-coated cold-rolled steel brackets for the writing tablet, a die-cast aluminum alloy support pedestal, stained solid beech wood armrests, and a plywood with wood veneer surface for the writing tablet, all assembled with steel fasteners. Functional design is tailored to public venue operational needs: the seat uses a gravity-activated automatic tip-up mechanism with a silent return buffer to reduce disturbance during entry and exit, rated for 100000 tip-up cycles, while the side-mounted fold-out writing tablet locks automatically in a horizontal position when deployed for stable note-taking or device placement. The floor-mounted fixed pedestal supports side-by-side ganging for continuous row configurations, the fabric achieves 50000 Martindale cycles of abrasion resistance to withstand frequent use, and the static seat load capacity reaches 150 kg per seat, with each unit weighing 28 kg net. This seating model is suitable for fixed installation in university and college lecture halls, performing arts venues, cinemas, large conference center meeting rooms, convention halls, government council chambers, public assembly rooms, and dedicated corporate in-house training facilities. For procurement planning, each unit ships across 2 cartons with a total packaged gross weight of 23 kg per set, requiring 40 minutes of assembly time per seat. Carton dimensions measure 850×420×720 mm per set, with a total carton volume of 0.26 m³ per set, allowing 135 sets to be loaded in a 20GP container at 85% space utilization.
