| I feel your pain!! Last fall I got a very adjustable but affordable chair from Staples; best one I've ever had. Reg. $199 and WORTH IT, but frequently on sale for $99. PLUS 30-day risk free trial, return no questions asked. Staples Carder Mesh Office Chair, Black http://www.staples.com/Staples-Carder-Mesh-Task-Chair-Black/... In addition to swivel, height adjustment and back height and tilt, it features a tilting seat "pan". This is crucial for changing how your spine is loaded. Tilt it forward to shift weight from your spine to your legs/knees/calves/feet. This helps you curve your lumbar spine. Then tilt it backward cradle your lower spine to reverse the lumbar curve for a time. Then zero it out level for a time. Rinse and repeat. The combo of the height and seat pan adjustments are the only practical way to achieve the position advocated by PTs, i.e., your hips should be above your knees; though this position should be only one of many you assume throughout the day. Also important: place chair on wood, tile or other hard floor, not carpet, and use plastic mat to make it easier to roll to/away from your desk without straining your back. Good luck!! |
