I haven't unboxed and set up yet, but arrived on time and Def has some I'm box weight to it. You might need help lifting it upstairs if you have them.(or a strong man/woman) 
*update* I set it up, well WE set it up. You'll Definitely need at least 2 people(you and another person) to set it up. It's really cute. Love the soft fluff patted material. It's pretty simple to put together.(like 6/10 on how easy the assemblage)
