I was afraid when I saw the packaging. The outer box looked pieced together with gaps taped over and it was coming apart. The tape job was impressive. But the plastic wrap inside was significant and protected the mattress. It puffed up pretty quickly once unwrapped and unfolded, and is perfect - firm and comfortable without being hard. it has a smell but it's not unpleasant. Kind of woodsy. I'm sure it will air out but I don't find it offensive and it might keep the cat from making herself comfortable. I couldn't be more pleased.
