Very poor quality, design and materials.  This chair was extremely difficult to assemble.  The predrilled holes do not line up and it took 3 people to squeeze the parts together and put the screws in.  I literally spent several hours trying to get the screws in.  After getting two people to help and finally get the chair assembled, the back is crooked and impossible to straighten.  Wayfair said I could return the whole chair for a refund but would have to pay shipping which is not a reasonable option as the chair is assembled and the base is impossible to disassemble. The 2nd option was for them to send me new parts which is not an option given the difficulty of disassembly. The last option was a  $28 refund to keep the chair.  All the options offered were unacceptable given the defects.  The chair is junk so do not waste your money or time on it.
