The High-Back Ribbed White Swivel Office Task Chair (model HB-RIB-OFC-001, unbranded) features a streamlined modern minimalist silhouette defined by crisp horizontal ribbed detailing across its all-white upholstery, paired with reflective polished chrome structural elements for a polished, uncluttered visual presence. Its balanced layout centers on a contoured high-back form paired with fixed cantilever armrests and a wide five-prong caster base, creating a proportional, professional profile that avoids visual bulk. Crafted for long-term use, the chair is built on a polished chrome-plated metal frame, with a 3mm thick polished chrome-plated aluminum alloy five-star base supporting the central structure. Both seat and backrest are wrapped in 1.2mm thick white PU leather, with tight channel stitching creating the signature ribbed texture, and padded with high-density molded polyurethane foam. The seat uses 50mm thick 45kg/m³ foam, while the backrest uses 30mm thick 40kg/m³ foam, with a 55% foam rebound rate. Upholstery is rated for 50000 double rubs of abrasion resistance. Armrests are formed from 2mm thick polished chrome-plated steel with no padded top, while the gas lift column is covered by a matching polished chrome telescopic steel shroud. The 3mm thick black powder-coated steel control chassis sits beneath the seat, paired with a Class 3 gas lift and 50mm diameter dual-wheel nylon casters fitted with black non-marking PU treads. Core functional features support flexible, comfortable seated work: 100mm of pneumatic seat height adjustment controlled via a right-side lever, 12-degree backward tilt with a lockable upright position and adjustable tension tuned to support users up to 150kg, and unrestricted 360-degree swivel around the central column. The dual-wheel casters roll smoothly across both carpet and hard flooring, while the fixed cantilever armrests position arms at a 90-degree angle aligned to standard desk heights. The contoured high back delivers full support for the upper back and shoulders to encourage upright working posture. This chair suits a wide range of commercial and residential spaces: its polished high-back design fits executive private offices, while its swivel mobility and adjustability make it appropriate for open plan workstations paired with 760mm high desks with minimum 600mm knee clearance. Its sleek, understated appearance aligns with formal conference room aesthetics, supporting easy repositioning during meetings. Its neutral white finish and compact footprint work well for home office settings, and its commercial-grade, durable construction holds up to the high-turnover use of shared coworking spaces. Procurement teams and individual buyers should note each unit ships in two cartons, with an 40 minutes of assembly time per chair. The packaged set has a gross weight of 23kg, and 20-foot container loads can accommodate 135 sets at 85% space utilization, supporting efficient bulk ordering for large workspace fit-outs. The chair supports a recommended static load of 150kg, with the five-star base rated for a static load of 1136kg, making it a reliable choice for consistent daily use. When planning space layouts, teams should confirm paired desks meet the minimum 600mm knee clearance requirement to ensure full functional compatibility.
