About this item
- 3.1-INCH ADJUSTABLE SEAT DEPTH: Slide the seat forward or backward to better match your leg length and improve thigh support. The adjustable seat depth helps users of different heights maintain comfortable clearance behind the knees.
- 65D MOLDED FOAM SEAT FOR LASTING SUPPORT: High-density molded foam balances cushioning and resilience while helping the seat maintain its supportive shape through extended use. The padded seat is designed for working, studying, and everyday computer use.
- 3D ARMRESTS AND ADJUSTABLE LUMBAR SUPPORT: Fine-tune the armrests for different typing and desk positions, while the adjustable lumbar support helps maintain the natural curve of the lower back during long periods of sitting.
- BREATHABLE MESH BACK WITH 135° RECLINE: The ventilated mesh back promotes airflow to help reduce heat buildup throughout the workday. Adjust the tilt resistance and recline from 90° to 135° for focused work, reading, calls, or short breaks.
- STABLE 330 LB BUILD AND EASY ASSEMBLY: The reinforced frame, five-point base, and smooth-rolling casters provide dependable everyday stability and mobility. Clear instructions, tools, and hardware are included for straightforward assembly.
