This is a very sturdy and quality built unit. The lowest seat position is taller than what most would want to use as a stool for use in kitchen food prep or such use. For me it works just perfect. I have back problems and need to sit while I try to cook and this works great to push around on my hardwood floors. I did order another set of casters that were made for wood floors after reading another reviewer that stated that they would recomend doing so. I am not sure if it was needed or not. I just did not want to take the chance.The legs are metal and strong so I feel that there will be no issues or problems with them. I bought a different stool made with plastic legs that had one break and I fell in a heap on the floor and with my numerous back fusion surgeries I really could have had a major problem on my hands! The backrest on this one is much nicer than the previous which lacked one.Shipping was very quick and because I choose the Super Saver Shipping it was no charge freight. Assembly was very quick and easy with just a Phillips screwdriver to attach the seat base and a hammer (I prefer rubber mallet) to tap in casters and foot ring / gas lift in place etc.The overall quality and fit and finish I think that you will find above average to most anything else that you will find anywhere near this price point. Those of you familiar to seeing the short medical stools that most Dr. office's have, I think will most often be this same brand and seat base- regardless of black or beige..... both colors available here. (only mentioned for you to use for reference).If any of this information changes after I use it further I will return and update the info!
