I see the Tama HT750 is pneumatic. I wonder how it compares to the HT741?
I chose not to get the pneumatic, as I have had seals leak on some chairs I've had. Since this is of top quality, it probably would stand up, but it is so fast and simple to spin the collar to adjust height, I am glad I don't have to worry about anything going wrong. The cowhide seat is very tough, and has no scuffs in three years.
The comfort level, especially with the backrest, allowed me to play three hour gigs last Sat. and Sun. very comfortably.
