Product Description

This Modern Dark Gray Upholstered Office Sofa Set, model OFS-3SEAT-ARM-CT01, is an unbranded office reception seating collection built for professional commercial and select residential spaces. The set comprises one three-seat sofa, two single armchairs, and a coordinating coffee table, with a cohesive modern visual profile defined by matte dark gray faux leather upholstery accented by tapered matte black metal legs, recessed decorative metal inlays on armrest outer faces, and complementary throw pillows: two dark gray faux leather pillows per seating unit paired with one contrasting orange fabric accent to add understated visual interest. The coffee table features a matte light gray sintered stone top, matte black powder-coated metal frame with vertical bar side detling, and a lower black tempered glass shelf, creating a unified, polished aesthetic across all pieces.
Construction prioritizes commercial-grade durability. Seating units are built on kiln-dried hardwood frames reinforced with metal corner bracing, supported by angled matte black powder-coated tapered metal legs fitted with non-marking plastic glides to protect finished flooring. Seat cushions use high-density, high-resilience polyurethane foam wrapped in polyester batting, while back cushions combine medium-density polyurethane foam with down-alternative fiber fill, all upholstered in 1.0mm matte dark gray faux leather with reinforced 8mm seam stitching. Seat support comes from spaced elastic webbing secured with metal clips, with fixed, non-removable seat and back cushions designed to prevent misalignment in high-traffic areas. The coffee table uses a scratch- and stn-resistant sintered stone top supported by a powder-coated square metal tubing frame, with a lower tempered glass shelf for open storage.
Designed for formal, upright seated postures, the set supports a total of five occupants, with open floor clearance under all seating units to accommodate routine cleaning access. The freestanding, modular components allow flexible arrangement to fit varied space layouts, while wipe-clean, stn-resistant upholstery and non-porous table surfaces simplify regular maintenance. Angled leg placement distributes weight evenly to prevent wobble on level flooring, and the two-tier coffee table provides open serving and storage space for reading materials or small accessories.
This set is well suited for corporate office reception lobbies, executive waiting areas, small meeting and breakout spaces, co-working common zones, and professional service waiting areas such as those in banks or consulting firms. It also works for refined residential home office spaces seeking a polished, coordinated guest seating setup. For procurement, teams should note the set ships in knock-down packaging requiring basic assembly, with legs packed separately to reduce shipping volume; purchasers should confirm exact material grades with suppliers prior to final order placement, and can pr the core set with coordinating side tables, floor lamps, and area rugs to create a fully furnished reception layout.
