I bought this mattress because I wanted a larger bed. The mattress arrives in a very long (~70") box, so it takes two people to set up. It is wrapped in layers and layers of plastic and expanded almost immediately. I was able to sleep on it the very same night. For the first two days the chemical smell was noticeable but not overly disturbing; it has now completely disappeared. 

I am a side sleeper, and this mattress strikes a good balance between providing good support and not feeling like a brick. It has now been a week and I have had great sleep every night! 

The only issue is that the mattress tends to get a bit warm, so for those of you who sweat a lot at night, caveat emptor. For everyone else, I highly recommend this mattress. :)
