Product Description

The Armless Upholstered Dining Chair with Black Tapered Metal Legs (model DC-ARL-UMB-001) from Kaida Sintered Stone delivers a streamlined modern seating solution anchored in clean, minimalist form. Its armless, fixed-frame silhouette pairs a smoothly contoured, upright backrest with a neatly proportioned seat, supported by four tapered, splayed matte black legs positioned for balanced visual weight and stable footprint. The cohesive, uncluttered layout works seamlessly across a range of interior palettes, with multiple upholstery color options including light gray, bright orange, black, and beige to align with varied design schemes. Constructed for lasting daily use, the chair features a durable internal frame secured with zinc-plated steel bolts and brackets, with internal seat support provided by bent plywood. Seating surfaces are finished in either 1.0mm thick matte PU leather or woven polyester fabric, upholstered with consistent, precision stitching. The seat is padded with high-resilience polyurethane foam, while the curved backrest uses medium-density polyurethane foam padding for targeted support. Legs are formed from cold-rolled carbon steel tube, finished with matte black electrostatic powder coating, and fitted with non-marking, non-slip PVC foot caps to protect hard floor surfaces. Functional design elements support comfortable, practical use: the ergonomic curved back promotes an upright dining posture, the four splayed leg configuration delivers anti-tip stability on hard flooring, and the wipe-clean upholstery surface simplifies routine maintenance. The chair uses a fixed, non-swivel, non-stackable structure, delivered as a knock-down assembly with all required hardware included for straightforward setup. This versatile chair fits equally well in residential and commercial settings. For homes, its compact armless footprint works with standard dining tables configured for six place settings, and its standard seat height pairs with standard-height desks for use as vanity or study side seating. In high-traffic commercial spaces, its durable metal frame and abrasion-resistant upholstery suits restaurants, cafes, and office break rooms, while its sleek, understated aesthetic complements modern hotel banquet spaces and guest room interiors. Procurement teams and individual buyers should note that each chair ships in two cartons per set, with packaged gross weight and volume aligned to standard freight loading parameters, supporting bulk order planning for large fit-out projects. Buyers can select between PU leather and woven polyester upholstery finishes to match specific maintenance needs and design priorities, and should plan for the documented per-set assembly time during installation scheduling.
