Product Description

The Two-Tone Upholstered Dining Armchair with Tapered Black Metal Legs (model DC-TT24-BM, unbranded) features a sleek modern minimalist silhouette defined by clean, unadorned lines and a deliberate two-tone visual scheme. The design balances soft upholstered seating surfaces with structured rigid elements: light off-white matte fabric covers the seat and inner back contact areas, paired with a dark brown molded composite outer back shell, all supported by slender black metal legs tapered 8 degrees outwards for a light, grounded visual presence. Integrated curved wrap-around armrests rise 230mm from the seat surface to a total height of 680mm from the floor, creating a cohesive, streamlined profile that avoids disjointed add-on components. Constructed for long-term regular use, the chair uses a fixed rigid frame assembled with zinc-plated steel bolts and brackets. The seat core uses 114mm thick high-density polyurethane foam rated at 35kg/m³ density with a 45% rebound rate, supported by a 12mm thick plywood internal panel and lined with non-woven polyester fabric under the upholstery. The matte fabric upholstery passes 30,000 double rubs of abrasion testing, with seams stitched at 8 stitches per inch for structural integrity. Legs are made from 1.5mm thick powder-coated black steel, fitted with non-marking non-slip black polyethylene foot caps to protect floor finishes. Each chair weighs 9kg, with a recommended static load capacity of 150kg, and delivers ergonomic support via its contoured upright curved back. Practical design features simplify day-to-day use: the spot-cleanable fabric allows quick removal of accidental spills, while the non-stacking fixed structure ensures stable, rattle-free seating. The chair is supplied for knock-down leg attachment, with an 40-minute assembly time per set, packaged across two cartons for delivery. Measuring 620mm wide, 620mm deep and 920mm tall, with a 510mm seat height, 490mm seat width, 460mm seat depth and 470mm backrest height, it fits a wide range of use cases. It pairs seamlessly with 750mm height standard residential dining tables for six-person sets, works as durable seating for casual commercial cafes, fits compact hotel guest room layouts for desk or dining use, supports upright short-stay seating in restaurant reception lounges, aligns with standard kitchen island counter overhangs for casual open-plan meals, and allows easy repositioning for temporary exhibition and event layouts. Procurement teams should note the non-stacking design informs storage and layout planning, while the knock-down assembly structure supports efficient bulk shipping, with 135 sets fitting a 20GP container at 85% space utilization. The fixed rigid frame delivers consistent performance across high-turnover and residential settings, with no moving parts to reduce long-term maintenance needs.
