Wow! Arrived earlier than expected but then Wayfair has been exceptionally consistent in customer service. Very easy to unpack age and it only took minutes to unfold! No smell and thank God because after a long day of moving, it couldn't have arrived at a more perfect time but the best of all was the perfect feel of it when I laid my tired achy self down for a great nights sleep!! I am so very glad I selected this topper. Admittedly I was a little skeptical at first because typical toppers are 4 inches. This one is beyond fantastic!! Not too soft, just perfectly right! So glad I took the chance!!
