First of all NO assembly instructions came with either package. I had to go online and search for the product at the manufacturer's website to see if there were any and was lucky enough to find similar products. I had to inventory all the parts as I thought I was missing key components of the structure. To my surprise the manufacturer had changed the assembly of key components which were not annotated on the online assembly instructions. After some deductive reasoning, I was able to proceed with the assembly of the product. Overall the product is well designed and was not difficult to assemble once the parts where identified and accounted for.  I highly recommend that better Quality Control be adhered to by the manufacturer. I do recommend the product but buyer beware you may have to do some research.....
