I bought this based on the reviews. We had no trouble assembling it, thanks to the reviews suggesting you just look at the order of assembly in the reviews, then figure out which hardware went where. We had no parts left over. It is a perfect fit to our Tempur-pedic CA King mattress, just enough room around the edges to put on covers. The support is just right. The bed is solid and does not squeak or jiggle when we get in. The lift mechanism works just fine, even with a heavy mattress. It arrives in 4 boxes and each clearly indicates the contents. The only heavy box is the one with the platform parts. I suggest opening this box instead of trying to carry it anywhere. There is no single part that cannot be carried upstairs by two average people. Once assembled, the bed it is heavy, so be sure to have it exactly where you want it after the headboard and footboard are connected to the side rails. It is handy to have scissors for opening the packaging and a socket wrench with metric and SAE sockets for assembly. We checked and tightened the feet on the headboard and footboard before assembly.
