Bests & Worsts Reviews from Amazon

I am almost embarrassed to admit this but in the 7+ years of shopping on Amazon & buying an average of 2-4 items per week in the last 4 years, I think I have maybe written one review years ago if any at all. However tonight I had to write one after reading the negative reviews & trying to cancel my order because of them but luckily it was too late. First of all this mattress is extremely comfortable, supportive and IS a memory foam MATTRESS. My photo was taken 10 minutes after opening & it had already expanded to 5". Why people are writing it only expanded to 2" I don't know, but I highly doubt that is accurate & it's irresponsible of them to write when that seems impossible. The photo of the mattress on the bag shows what it would look like from the inside but it's not supposed to actually look like the photo, LOL. The "chemical smell" I read about is why I wanted to cancel my order because I am very sensitive to odors etc...this is so minor, to be expected & already dissipated. What a wonderful deal this was & I am so happy I purchased this for our guest room. Love it!
