Product Description

The LGS-4CH-ST600 is an unbranded four-seat upholstered lounge seating group presented as a coordinated modern arrangement. It includes four tub-style lounge armchairs paired with a square side table, producing a balanced layout suited to reception, breakout, waiting, executive lounge, and relaxed residential settings. The chairs use soft, enclosed forms with armrests and padded backs, while the square table provides a compact central or adjacent surface for drinks, documents, and personal items. The multicolor finish category supports coordination with varied interior palettes, subject to selected upholstery and finish availability. Each chair is upholstered in fabric over foam padding. The finished seat cushion is 90 mm thick, and the backrest padding is 70 mm thick, with a 240 mm high lumbar support zone and 540 mm clear width between the armrests. Reference foam values include a 45 kg/m³ seat cushion with 65 percent rebound reference and 38 kg/m³ back foam. The upholstery reference is 1.4 mm thick with a 50000-cycle abrasion reference and 4 mm seam pitch. Exact fabric composition and substrate should be confirmed through the supplier bill of materials. Internal construction uses a 14 mm bent plywood or equivalent seat support board and a 14 mm bent plywood or composite reinforced back frame. The mobility and adjustment system is based on a Class 4 gas lift recommendation with a 50 mm outer tube and 100 mm stroke, a 2.5 mm cold-rolled steel tilt mechanism plate, and a 3.5 mm metal-wall five-star base with a 700 mm diameter. Five 60 mm PU-tread swivel casters provide 360-degree rotation and multidirectional movement. Functional references include continuous 100 mm height adjustment, recline to 125 degrees with three suggested lock positions, and tilt tension adjustment referenced for users up to 120 kg. The five-star base static-load acceptance target is at least 120 kg, with a 150 kg chair reference load. Caster rolling durability and gas-lift cycling carry acceptance targets of 30000 cycles and 100000 cycles respectively. The reference daily-use duration is eight hours, to be confirmed by ergonomic testing for the intended application. The side table features a composite wood top and a brushed metal pedestal-style base, complementing the chairs’ modern lounge character. Procurement teams should verify material composition, color, finish, casters, mechanism performance, and supplier warranty terms before purchase. The group ships as one set in two cartons, with 23 kg packaged gross weight, 0.26 cubic meter volume, and 40-minute reference assembly time. It is shown with a 2.4 m executive desk as a matching reference.
