The YOUZHUO Geometric Block Modular Upholstered Sofa Set, model MOD-BLK-OLVORG-3PC, delivers a retro geometric aesthetic defined by clean, blocky modular forms that create structured, visually balanced seating arrangements. The full 3-piece configuration spans 3920 x 980 x 750 mm, composed of one 1960 x 980 x 650 mm armless central two-seat module and two 980 x 980 x 750 mm single armchair modules, with a uniform 980 mm depth that creates a cohesive, streamlined silhouette across all layout options. Key dimensional details include a 450 mm floor-to-seat height, 600 mm usable seat depth, 600 mm armrest height on chair modules, 180 mm thick backrest cushions, and 220 mm thick seat cushions, lending the set a substantial, grounded presence suited to curated interior schemes. Built for long-term regular use, the set features a 30 mm thick kiln-dried solid pine and plywood internal load-bearing frame, supported by 50 mm wide high-tension elastic webbing spaced 80 mm apart for even weight distribution. External upholstery uses 380 g/m² woven chenille-look polyester fabric rated for 30000 Martindale abrasion cycles, with multi-layer high-resilience polyurethane cushion fill: seat cushions use 45 kg/m³ density foam with 60% rebound rate, while back cushions use 35 kg/m³ density foam for balanced support. Modules connect via 3 mm thick aviation-grade aluminum spring clips rated for 50 kg load, with hidden 10 mm high non-slip plastic glides at floor contact points. The total set net weight is 120 kg, with 150 kg load capacity per seating position. Functional design supports flexible, low-maintenance use: the aluminum clips enable tool-free reconnection to arrange modules into straight or L-shaped layouts, while integrated hook-and-loop strips hold cushions firmly in place during use to prevent slippage. All cushion covers feature zippered, fully removable designs for simple spot cleaning or laundering, and the low-profile glides prevent scuffing on polished hard flooring. The set arrives in 2 cartons per set, with 40 minutes of reference assembly time required for full setup. This sofa set is well-suited for residential living rooms with modern retro interiors, where it serves as a main 4-seat conversational seating group that anchors shared gathering spaces. It also performs appropriately in office lounge areas, including informal breakout zones and casual waiting spaces that prioritize approachable, adaptable comfort. For procurement, teams should account for the 1.8 m³ reference packaging volume and 110 kg packaged gross weight per item to plan delivery, storage, and installation logistics accurately, and confirm that layout dimensions align with intended space plans prior to purchase.
