First impression wasnt that great since the box was very beat up. With help I got it in my room it was wrapped in an outer sleeve of plastic then another that holds the mattress. It fully inflated quickly. I needed a mattress with more support, I had a pillowtop for 10 years previously and had a lot of wear. I woke up with constant low back pain so after reading the reviews and constantly looking I settled on this Lucid. It has great support and I havent gotten hot in the week Ive had it. Im not sleeping fully throughout the night liked I had hoped but I am not using pillows to support my hips like I did with my old pillow top. I dont believe this is to firm or to soft it is just right in a medium support. 4 stars for mainly the packaging and even after over 24 hours without laying or putting sheets on it is short about a inch and a half. Overall a decent quality mattress.
