Super convenient, easy to unpack, it fluffed up almost immediately, but I gave it 72 hours before using it just in case. Zero smell to it, and doesn't appear to contain fiberglass according to the label. Not as soft as I was expecting - more like a 3.5/5 firmness. Sometimes I wake up with mild shoulder pain. My lower back feels better than it did with my old mattress, though. Overall, pretty good mattress for the price.
