The dimensions of the bar stool on the site said the maximum height was 33", however, it only measured at a 31" maximum height after assembly; and after I sat in the chair it lowered down another 2 inches to 29" (I weigh 210 lbs).  The minimum height is exactly 25" as advertised.  To conclude, all four bar stools I purchased measured the same and appear to be of good quality.  Just wish they were 4" taller when i'm in them.
