This cat tree arrived with a warped and cracked bottom board along with a defective bottom rope handle that did not have the screw threads inside one end of the plastic ends which prevented it from being screwed into the bottom board below the cat hammock.  Rather than hassling returning it, I paid $14.00 dollars for a new rope handle I ordered from Archie & Oscar and have lived with the cracked base board because it did not go all the way through and appears to provide enough stability. My two cats enjoy climbing and hanging out on the two perches the most and completely ignore the cat hammock.  It's a good, easily adaptable product for cat lovers, but the quality control was certainly an issue for me.  In terms of the buying experience, nothing is more frustrating than to have the anticipation of a new item arrive only to discover damaged and/or defective parts.
