I just put these together and have sat in them for less than 5 minutes, but so far so good based on my experience putting them together. The first chair took me about 45 min to an hour, but I was taking my time. The second chair was done in 15 minutes.  If you plan on buying these, note that there is a Velcro lining you will need to remove to assemble it!!! I got so confused but once I figured that out, it was smooth sailing. Aesthetically, these chairs are sleek and very well made. Perfect height for my 32 inch island. Highly recommend!
