Practitioners in Human Factors and Ergonomics

Hi everyone, I'm looking for some insights on workspace setup. Lately, I've been dealing with persistent lower leg numbness and thigh pressure during long hours at my desk. I adjusted my chair height according to standard guidelines, but the issue persists. I was reading a case study on AdsNovia Desk Comfort about how seat depth and improper lumbar alignment compress nerves over time. For those working with long-shift professionals, do you recommend switching to a mesh-based ergonomic chair to reduce under-thigh pressure, or should I look into active footrests first? Would love to hear your professional thoughts.
