Product Description

The Cognac Leather L-Shaped Three-Seat Sectional Sofa presents a clean, contemporary profile with an open L-shaped layout suited to both social seating and relaxed lounging. Its low back, dark back rail, polished metal tubular legs, and cognac upholstery create a tailored visual balance between warm leather-look surfaces and refined metallic detailing. The configuration uses two bolt-aligned seating sections, allowing the sofa to be transported in split modules while forming a stable sectional layout in the room. Three divided fixed seat cushions establish independent sit zones, while three removable loose back cushions and a right-corner pillow support upright or more relaxed sitting postures. Four fabric throw pillows are included to soften the angular form and add layered comfort. The sofa is unbranded, identified by model LTH-L3-COG-3400, and is classified as a modular sofa. Construction centers on a kiln-dried hardwood and engineered timber frame with structural members, set over a support deck made of wood-composite suspension board and S-shaped steel springs. Seat cushions use high-resilience polyurethane foam with a stated cushion core thickness and density, and the back cushions combine dual-layer foam with fibre wrap. The outer cover is offered in cognac smooth leather or leather-match upholstery with precision edge stitching. Eight slender polished chrome or brushed stainless-steel tubular legs support the frame and are fitted with non-marking floor glides. The elevated leg height leaves clear space beneath for routine floor cleaning. Designed to seat three adults, the sectional is appropriate for commercial settings such as executive lounges, lobby waiting zones, reception areas, and informal meeting spaces. Its low-profile, chaise-style character also suits premium residential use, including contemporary living rooms and open lofts where cognac upholstery is a desired feature. Procurement planning should account for delivery as one set across two cartons, with an assembly reference of forty minutes per set. The packaging and gross-weight details should be reviewed for freight, elevator access, storage, and installation logistics. Buyers should also confirm upholstery selection, finish choice for the metal legs, site layout, and maintenance expectations before purchase.
