Description

This managerial-style office chair combines a wide, supportive seat with a tall ergonomic back to suit big and tall users. The integrated headrest and contoured backrest follow the body’s natural curve to relieve neck and upper back fatigue, while the thicker seat cushion—filled with high-density sponge and an internal elastic spring—adds lasting comfort for long periods of sitting.

Adjustable features include a gas-lift seat height (116–124 cm) and a rocking backrest that reclines within a 90°–115° range. A full 360° swivel and smooth rolling casters give you freedom of movement around your workspace, while a heavy-duty metal base and Class-4 gas rod provide sturdy support and reliability under heavier loads.

Padded armrests have been redesigned to sit at a comfortable level without pressing on the thighs, improving ergonomics for prolonged use. The black PU upholstery gives the chair a smart, easy-to-clean finish that suits both home and commercial offices.

Designed with simple modern lines, this chair fits a variety of settings from private studies to meeting rooms. It offers an accessible combination of large-seat comfort, robust construction and adaptable recline for everyday working, studying or gaming.

  • Built for bigger frames: wide seat and strong metal base rated to 227 kg to give secure, long-term support.
  • Comfort-first cushioning: thick high-density sponge with elastic spring inside provides a resilient, comfortable sit throughout the day.
  • Flexible positioning: height-adjustable range and 360° swivel let you find the right posture; rocking backrest gives extra relaxation when needed.
  • Practical finish: black PU upholstery is tidy and simple to wipe clean, so the chair keeps a smart appearance with minimal upkeep.
  • Stable under pressure: Class-4 gas lift and heavy-duty base give a sturdy platform for frequent use and easy mobility via smooth casters.
  • Ergonomic detail: integrated headrest and shaped high back reduce neck and upper back strain during long seated periods.
  • Padded armrests sit comfortably without restricting leg position, improving overall seating comfort for extended tasks.

FAQs



What steps help preserve the seat cushion and keep it comfortable over time?


Protect the sponge-filled cushion by avoiding prolonged exposure to strong sunlight or direct heat, which can dry out materials and cause fading. Blot spills quickly with a clean cloth rather than rubbing. Rotate your sitting position periodically to reduce uneven wear, and allow the chair to air when possible to prevent moisture build-up in the padding.




How should I clean and maintain this textile?


Follow any care label provided. For routine care, vacuum on a low setting with a brush attachment to lift dust. Blot spills immediately—do not rub. For washable items, use a gentle cycle and mild detergent; for delicate fibres or structured pieces, professional dry cleaning is recommended.




My new rug/throw is shedding—what should I do?


Light shedding or lint is normal at first for many natural fibres. Vacuum little and often in the direction of the pile for the first few weeks. Avoid strong rotating brushes which can pull fibres. Trim long loose fibres with scissors rather than pulling.
