I have a king size one from Costco...I remember it was like fighting a bear just to unroll it, and then it took nearly a week for it to fully plump up and destinkify, it was soooo compressed when I got it. I think even the paperwork warned of this urethane odor situation. But now, ahhhhh, I can't imagine life without it. Make sureyou have a coverlet for it because it's rubbery and tidbits stick to it.
I was about to order one from Serta via Overstock when I read reviews that said it smelled. The ones I've gotten from Costco were fine- but they don't have that kind anymore. Who has bought one from Walmart or Overstock or elsewhere, and did it have a strong odor? Did the odor go away?
