Beautiful, nicely made piece of outdoor furniture; very comfortable, too.  
It's easy to put together--only 8 bolts, plus four legs to attach.  Remember not to tighten any of the bolts until all are in place; this way it is easy for the parts to line up. The hardest part was putting the legs on; the nyloc locking nut is hard to turn, especially upside down and with that little wrench.  Swap out the wrench if you can; I didn't have one the right size, so I wrapped some foam rubber around it with duct tape and it was much easier to grip.  Some wax on the threads makes it easier to turn as well.  Also, it is MUCH easier to attach the feet BEFORE assembling the loveseat.
