Unlike basic lumbar support office chairs that simply target lower back cushioning, ergonomic models take complete spinal alignment into consideration. Through customized features that calibrate to individual user proportions, ergonomic chairs like Ovios' designs conform to the head, neck, shoulder, and hip postures for full support. Adjustable seat heights from 16-22 inches, depths, pivot armrest widths, and tilting seat angles facilitate personalized comfort for the way you sit. This total body approach aims to eliminate circulation loss, disc injury, and muscle strains that accompany poor computer postures when sitting inactive for consecutive hours. Yes, ergonomic chairs exceed basic lumbar cushions in price, but their health benefits also exceed much further by cradling the entire spine's natural curvature, not just isolated problem regions. For those occupying desks most of the day, invest in complete ergonomic support.
