Update  we were eventually able to assemble this greenhouse.  It took several days but was easier than trying to return. The door has never slid right and often gets stuck.  Less than six months after assembly and we have holes chewed in the side. Too pricy for the quality 

We have yet to put this together.  It took 4 very smart people pretty much a full day to put one panel together and we dont have that kind of time to finish it right now.   Parts are mislabeled, instructions are missing.  There is no possible way to put this together per the instructions.   I will be attempting to return if we dont have better luck the next time we can dedicate a day to this.  Pretty Disappointed Wayfair.
