chair came with pre drilled holes , easy assemble.  However one leg was shorter than the other, so the chair wobbles back and forth. Also there is a large tag on the bottom of the chair that reads warning, law requires that company must advise those in the state of California, this product contains materials that can cause cancer. WHAT???????????  I think this should be an advisement to everyone, had I been able to see that at purchase I would have chosen another product, or not purchased anything at all. If I could leave a negative star I would. No more shopping online for furniture for me.
