ABSOLUTELY LOVE!  We were nervous but given the price and the shape of our last mattress, we had nothing to loose!  The package is heavy but set up is quick. Our old mattress was 14" so that's what I ordered however, it seems taller and we easily could have done with a 10" or 12" mattress.  Ordered a plush mattress and it feels deceptively firm yet, is truly a great sleep.  There is minimal movement with a partner as in, IF you are awake you will notice if they get out of bed or make a major movement but barely. All in all, the risk was absolutely worth it and we are sleeping very well for the first time in years!
