I purchased the 34" high stool and I would say that this is just ok!  I am not happy with some things about it. First of all, I found it very hard to assemble.  It took me almost 3 hours to assemble the first chair.  I am sure the others would be quicker to install however.  
The chair is quite comfortable to sit on but it is too high and my feet are about 5 inches from the floor  (I am 5' 8" tall).  Also the foot rest is too high to rest your foot on comfortably.  Also before even getting the stool completely assembled, I have discovered 2 places where the finish has already been chipped and the light wood under the finish if showing.  I will have to find some black paint to cover up the chips and I haven't even used the chair for one day.  
Overall, I would not recommend purchase of this chair unless you are over 6' tall.
