just recently upgraded to a king bed so we needed to upgrade our mattress. After putting in on the bed realized I could have gotten a higher mattress but its all good. The mattress is very nice. My bf & I love it so far. It comes rolled up. Once you open the box its packaged in 2 separate plastics. You have to cut one first & then the 2nd one. The mattress will unroll & inflate to its size. I'm very pleased with this purchase. I paid for expedited shipping (regret it because we had to sleep on it on the floor since our bed was like 3-4 days late) but regardless, we were told it would get here by Thursday but we received it Wednesday so that was cool.
