I noticed the other day while pursuing the forums, that my ass was not quite as padded as it used to be. This led to my now somewhat boney ass aching while sitting at my desk. I couldn't have that so I started browsing Amazon for replacement chairs and settled on a Serta Hensley, as it is designed for big and taller people. The chair has honest to God springs in addition to the foam padding in the seat. It went together fairly easily, although my better half had to do almost all of the work as I have Rheumatoid Arthritis and have been sick this week. The chair is quite comfortable for my 5'11" 235# frame and well worth the money I spent. I did go ahead and buy some better wheels as my office is carpeted and the chair wheels are designed for smooth flooring.
