Product Description

This light gray vertical channel-stitched upholstered dining armchair features a clean, modern minimalist silhouette defined by its structured four-leg fixed frame and integrated armrests. The backrest carries tailored vertical channel stitching that runs its full height, paired with smoothly padded armrests that align flush with the seat’s curved edges, creating a streamlined, uncluttered visual profile balanced by the contrasting matte dark gunmetal finish of its metal frame. The chair is built for long-term durability across frequent use. Its structural core uses powder-coated dark carbon steel tubing with welded under-seat cross bracing to connect all four legs, reducing wobble during regular use. The seat rests on a rigid internal bent plywood support board, topped with a high-density polyurethane foam cushion wrapped in Dacron for a soft but supportive sit; the curved, channel-tufted backrest uses molded polyurethane foam to deliver continuous lumbar support. All seating surfaces are upholstered in a light gray polyester-blend performance fabric, with matching fabric covering padded armrests mounted to steel support structures. Each leg base is fitted with non-scratch nylon glides that glide smoothly across hard flooring without leaving surface marks. Designed for upright, supported seating, the chair holds a fixed 105-degree seat-to-back angle optimized for formal and casual dining use, with steel-reinforced armrests built to support regular static load. Its knock-down bolted leg connection design simplifies shipping and on-site assembly, and both upholstery and frame finish are available in multiple custom color options to match existing interior schemes. This armchair fits equally well in residential and light commercial spaces. It works for home dining rooms and small apartment breakfast nooks, pairing seamlessly with standard height dining tables to offer ergonomic arm clearance during family meals. It is also suited to cafe and bistro seating, hotel guest room desk placements, and office break rooms, where its durable frame, easy-clean fabric surface, and comfortable padding support regular daily use. When procuring this model, note that units ship across two cartons per set, with straightforward assembly required on receipt. The product is unbranded, carries fixed core dimensions aligned to standard dining table heights, and is built to support recommended daily user weights for regular, non-heavy-commercial dining and seating applications.
