Mattress arrived in good condition.  It took both of us to get it up the stairs and onto the platform bed frame.  It was fully expanded within a day and the odor from the foam was gone in less than two days.  We have had the mattress for almost two weeks.  My husband is no longer waking up with his right arm being numb.  The quilted bamboo charcoal memory foam top has kept him cool -- he hasn't complained about being too warm.  The depth of a 16" mattress is a plus for larger size people and how many products these days come with a 25 year warranty?  Happy so far with this purchase!
