Easy to assemble and very comfortable. We ordered 6 and 1 came with a small rip in the back. We didn't contact the company because they are for out in our barn. I had to contact the company about something else and I'm sure they would have replaced it if asked.
I recently purchased 16 chairs for my basement and I was very pleased with how solid and heavy duty these chairs are!! Assembly was easy with 4 bolts into the bottom of each chair with predrilled bolt housings, every one lined up with no issues. It will take you longer to remove the protective wrap then it does to bolt the seat to the base! LOL For the folks in other reviews saying they lean forward, you assembled them incorrectly. I know because I did the same thing on a few of the first ones I did. Make sure you follow the instructions on the install guide as you need to line up the base where is says "Top" and bolt that to the FRONT of the chair so the seat leans slightly back and then you are all set. These should last you years no doubt at all!
