This was my first purchase from Wayfair and I am completely satisfied. The bunk lived up to the reviews. Shipment came in two boxes delivered together.  FYI the instructions and hardware is in the long box. Make sure you don't lose any screws/bolts since there are no extras which is also the only way to know what is needed with each step.  
My 5 and 2 yr old are thrilled with their bunk bed. I would recommend this!
