Product Description

The SOF-113-DGLB-001 upholstered sofa set from Hongsheng Dining presents a polished, conversation-focused 1+1+3 configuration designed for cohesive modern luxury interiors. Arranged in a U-shaped layout, the set centers on a three-seat sofa flanked by two matching single armchairs, with consistent 830 mm depth and 850 mm total height across all pieces; the three-seat unit spans 2120 mm in width, while each armchair measures 1160 mm wide. The design features light blue matte performance fabric upholstery, accented by 15 mm wide brushed gold-finish metal trim along frame edges and hardware, complemented by dark gray finished wood support feet fitted with non-slip rubber base pads. Included throw pillows use mixed light blue, gray and beige woven fabric with contrast stitching to add layered visual texture, pairing seamlessly with coordinated rectangular coffee tables and square side end tables for a unified furnishing scheme. Built for lasting structural integrity, the outer frame uses kiln-dried solid walnut with high-density fiberboard reinforcement, with primary timber sections measuring 30 × 50 mm and moisture content maintained at 12% to reduce warping risk. Internal joints are secured with dowels, corner blocks, and metal screw fasteners, while evenly spaced support blocks distribute weight evenly to prevent floor indentation and long-term sagging. Seat and back cushions are filled with 42# high-resilience polyurethane foam topped with a 40 mm soft sponge layer, delivering a 60% foam rebound rate; the 120 mm thick seat cushions sit at a 450 mm floor height, with 600 mm depth and 480 mm tall backrests, and armrests positioned 180 mm above the seat surface. Upholstery undergoes folded and lock-stitched edge binding to resist fraying, with 8 mm seam stitch pitch and 50000-cycle abrasion resistance, and cushions are removable for easy cleaning, rotation, or replacement. The stain-resistant fabric wipes clean with a soft damp cloth for simple daily upkeep. With a total recommended seating capacity of 5 people and a per-seat static load capacity of 150 kg, the set suits adult users in both residential and light commercial settings. It works as primary seating in open-plan residential living rooms, and fits high-end office executive reception lounges and VIP waiting areas, complementing modern luxury, light modern, and new Chinese interior design schemes. Spaces measuring 25 square meters or larger are required to accommodate full U-shaped layout clearance. For procurement, note that each set ships in 2 cartons, with a 40-minute assembly time per unit, and the fixed non-reclining structure does not offer adjustable positioning.
