## Long description

The SUNFLEX SUNFLEX MB (model 250405) is an office chair designed for desk use, featuring an ergonomic seat profile and adjustable height to support daily office or home workstation activities. The chair provides fundamental lumbar and thigh support through a contoured seat and a mid-height backrest, and it is compatible with standard desk heights. Materials and construction are intended for routine administrative tasks, study sessions, and meeting use.
Advantages
The ergonomic seat shape reduces pressure on the thighs and encourages a neutral sitting posture while the pneumatic height adjustment allows fast, tool-free adaptation to different desk levels and user heights. A compact footprint and simple adjustment mechanism make the chair practical for shared or multi-purpose workspaces. The design balances support and mobility for typical office tasks without complex controls.
Suitable for
Everyday office work at standard desks
Home study and remote workstations
Meeting rooms and conference seating
Administrative and reception areas
Key specifications
Seat: ergonomic contoured seat for reduced pressure points
Height adjustment: pneumatic gas lift with continuous height range suitable for standard desk heights
Backrest: mid-height backrest providing basic lumbar support
Base: five-star base for stability and caster mobility
Upholstery and padding: durable fabric or synthetic covering with foam padding designed for everyday use
Intended use: indoor office and home environments
How to use
Sit with your back against the mid-height backrest and adjust the seat height with the lever beneath the seat so your feet rest flat on the floor and your knees are approximately at a right angle. Position the chair so the forearms are parallel to the desk surface when typing or writing. Use the casters to move the chair smoothly across the floor and avoid dragging the base on delicate flooring. Periodically check and tighten visible fasteners to maintain stability.
Usage recommendations
For prolonged sitting, combine the chair with regular standing breaks and simple stretching to reduce fatigue. Match the seat height to desk height and consider a footrest if feet do not reach the floor comfortably.
