I was able to assemble this bench by myself. Only the foundation with the two upright would have been easier with an extra hand. All the pieces were present. One of the barbell supports had some damage in shipping and with one call to warranty service a replacement was authorized (but backordered). The equipment is still fully functional, but of course I paid for undamaged fully functional. My sole complaint after about 1-month is the difficulty in adjusting the bench/seat with the screw in pin. Why couldn't Marcy have put in a quick release pin. This addition to my home gym allows me to do a vast array of routines and it love how it folds up, opening up the workout area for exercises -- not monopolizing a huge amount of space.
