Product Description

The Mid-Back Upholstered Swivel Conference Chair, model OFC-MB-CRM-5STAR-01, presents a refined executive seating profile with beige smooth upholstery, a padded mid-height backrest, and matching curved loop armrests. Its back panel features stitched perimeter detailing and subtly rounded corners, while the polished aluminum five-star base and black twin-wheel casters create a balanced contrast between soft visual warmth and structured metallic support. The fixed armrests provide a formal, enveloping frame and offer 230 mm of forearm support. Overall dimensions are 620 x 620 x 1010 mm, with a 540 mm clear width between arms, a 90 mm finished seat cushion, 70 mm backrest padding, and a 240 mm lumbar support zone. Construction centers on a molded polyurethane seat cushion with a 45 kg/m3 target density and a shaped polyurethane back cushion with a 35 kg/m3 target density. The visible upholstery is beige and smooth, though the precise material composition requires bill-of-material confirmation between leather, synthetic leather, or coated fabric. Beneath the cushion is a 12 mm molded plywood or steel seat shell bolted to a black steel multi-position tilt mechanism. The back uses a rigid internal board or steel frame, with black side hinges visible at the recline pivots. A Class 4 procurement grade, 50 mm chrome-plated steel gas lift provides a 100 mm height-adjustment stroke. The chair supports pneumatic seat-height adjustment from 430 to 530 mm and full 360-degree swivel on the fixed five-star base. Recline movement extends from an upright 95-degree angle to 107 degrees, controlled through a synchronized or center-tilt mechanism, an upright lock and release lever, and an under-seat tension knob suited to users up to 136 kg. Five 60 mm twin-wheel casters allow omnidirectional movement on hard floors and low-pile carpet. With a 17 kg net weight and an 8-hour daily-use recommendation, it is suited to boardrooms, private executive offices, open-plan work zones, manager meeting rooms, reception areas, and consultant rooms. Procurement teams should confirm exact upholstery material, caster tread suitability, assembly planning, and packaged logistics: each set ships in two cartons with 23 kg packaged gross weight and a 40-minute reference assembly time.
