The Black Metal Frame Padded Square Stool from Kaida Sintered Stone, model STL-SQ-MBLK-350, is an upholstered metal frame square stool defined by clean, minimalist visual lines and a space-conscious square layout. Its matte black finish on the structural frame pairs seamlessly with smooth black upholstery, creating a low-profile, unobtrusive silhouette that fits seamlessly across a range of interior design schemes without overwhelming surrounding decor. The stool’s construction is built for consistent, long-lasting use. Its structural frame uses 1.2mm thick Q235 steel tube with a black matte powder-coated finish, with MIG-welded joints ground smooth and finished with matching powder touch-up to eliminate sharp edges and prevent unsightly corrosion. The seat attaches to the frame via cross-head steel screws secured through the frame top rail into a 12mm thick MDF under-seat support board, paired with a 14mm bent plywood internal seat support board for consistent structural stability. The seat features a 0.8mm thick stain-resistant smooth black faux leather surface, over a 30kg/m³ high-resilience polyurethane foam core with 90mm total finished cushion thickness; 5mm thick non-slip PE plastic foot pads line the base of each frame leg to avoid hard metal contact with finished flooring. The frame is rated for a 200kg static load, while the seat supports 150kg of static vertical load, and the seat foam delivers a 92% compression recovery rate to hold its shape over regular use, with a recommended maximum continuous use duration of 8 hours. Practically, the stool features a rigid fixed non-swivel seat with no rotation or tilt for stable seating, and a fully stackable nesting design that supports stacking up to 10 stools, with each nested stool adding just 50mm of stacking height for compact storage. The knock-down design requires only 4 screws to attach the seat to the frame, with an assembly time of 40 minutes per unit; the stool sits stably on both hard floors and low-pile carpet without caster attachments, and its smooth faux leather surface wipes clean easily to address spills during regular use. This stool is well suited for a wide range of public and private spaces: it works as flexible, high-traffic temporary seating for office visitor waiting areas, supplementary seating for dining and conference spaces (with its seat height aligned to standard table heights), fast-deploy temporary seating for events, space-saving multi-use seating for small compact apartments, and casual, easy-to-clean seating for workplace break rooms. For procurement planning, note that each set ships across 2 cartons with a total packaged gross weight of 23kg, and a 20GP shipping container can hold 135 sets at 85% space utilization. Coordinate seating quantity to match projected peak occupancy, and account for assembly labor timelines during deployment scheduling.
