First of all I had to have help getting the box in the house because the weight of this was more than I could carry  the quality of the bed is super. It took me about an hour and half to put together  I followed each step to the tee on the instructions. The pets are numbered so that it was super easy to follow . I ordered the King but my mattress hangs over in the front about 3 inches  but still a very solid bed without any movement . I would recommend this bed . Oh yeah I forgot to mention that I really love that it has a usb built in to plug in my phones
