Description

The MASTER Mesh is built for power users who spend 10-12+ hours at their desk. Full mesh construction keeps airflow moving throughout long sessions, so you stay cool whether you're deep in work or a late-night grind. Features include 3D adjustable armrests, 135° recline, and breathable mesh throughout the seat and back. Available in red or blue. When your chair is your workstation for half your life, staying cool is not a luxury.

Key Features

✓ 3D Adjustable Lumbar Support – Fine-tune height, angle and depth to position support exactly where your spine needs it, reducing lower-back pressure during intensive work or gaming sessions

✓ Upgraded Breathable Mesh Backrest – Enhanced mesh on the headrest and backrest improves airflow and long-session comfort, helping prevent heat buildup when you’re locked in for hours

✓ 3D Adjustable Headrest – Configure height, depth and angle to maintain consistent neck support in both upright and reclined positions. Removable for a cleaner backrest profile

✓ 3D Adjustable Armrests – Precision adjustment in multiple directions keeps forearms supported and wrists aligned for keyboard, mouse, or controller use—reducing shoulder and neck fatigue over long days

✓ Seat Finish Options: Mesh or Fabric – Choose breathable mesh for maximum ventilation, or fabric for a softer feel during extended sessions

✓ Sliding Seat Base – Adjust seat depth for proper thigh support and improved circulation across different heights and sitting styles

✓ Multi-Function Tilt + 135° Recline – Lock in a stable upright position for focused work, or recline further for proper recovery between sessions

✓ Lightweight Frame + 360° Swivel Base – Smooth, controlled movement around your setup without the bulk of a heavy office chair

✓ Colour Options: Red or Blue – Match your chair to your space without compromising on ergonomic performance
