This mattress is beyond what I expected in quality and comfort. I ordered a King Size. It came in a large, weather proof, duffle type bag. I was able to easily maneuver it inside and to the correct room by myself. Once I opened the bag and unsealed the inner bag it was almost instantly the correct size. I did let it set for 48 hours before lying on it but honestly I did that only because I was in no rush. I am very sensitive to chemicals and such… there was zero odor. And the comfort… Ahhhhhhhmazing!!! I give this product 5 Stars because of Cost/Value, Packing/Shipping, Comfor/Quality. I could not be happier. I highly recommend.
