The Charcoal Channel-Tufted Sculptural Lounge Armchair with Matching Ottoman (model LCH-MBASE-CHAR-OTTO01) is a fully upholstered, legless contemporary seating set defined by its sculptural folded M-base profile, with continuous formed armrests that flow seamlessly from the seat edge to the channel-tufted backrest for a cohesive wraparound silhouette. The matte dark charcoal polyester velvet upholstery offers a soft, low-luster finish, with precise 8mm seam pitch stitching creating structured channel detailing across the backrest for visual depth without disrupting the piece’s smooth, monolithic form. Built for durable residential and light commercial indoor use, the set’s internal structure uses 18mm thick CNC-shaped birch plywood to form its fixed M-base, reinforced with 2mm powder-coated steel cross bracing and a 14mm bent plywood seat support board for stable load bearing. Seating surfaces are padded with high-density polyurethane foam: 80mm thick 42kg/m³ foam forms the seat, 60mm thick foam supports the back, and armrests use the same high-density foam wrapped in soft polyester wadding for plush, even comfort. The 0.8mm thick upholstery features a stain-resistant nano-coating for easy spot cleaning, and holds 30000 Martindale abrasion cycles for long-term wear resistance. Non-marking 5mm thick black felt glides fitted to the base edges prevent scuffing on hard flooring surfaces. The set is engineered for relaxed, static seating with no recline, swivel, or height adjustment functions. The backrest holds a fixed 108-degree angle to support upright lounge posture, and the ottoman sits at an aligned 420mm height matching the chair seat to enable full leg elevation for extended comfort. The chair supports a 136kg static weight capacity, while the ottoman supports 125kg; maintenance is limited to regular vacuuming and spot cleaning with mild upholstery detergent. Minimal assembly is required if shipped knocked down, with only four glides to attach, taking an 40 minutes per set, and the product is covered by a 1-year limited warranty. This seating set is well suited for residential living room reading nooks, conversation areas, bedroom bedside or dressing zones, as well as informal office breakout spaces and boutique hotel lobby or suite lounges. It is safe for use on hardwood, tile, vinyl, and low-pile carpet surfaces, and is ideally paired with a small round side table for holding drinks or reading materials. For procurement, note the set ships across two cartons with a total gross shipping weight of 45kg, and that the unbranded set is designed exclusively for indoor residential and specified light commercial settings, with no outdoor use rating.
