First thing, customer support is second to none! My first mattress was lost by UPS. I contacted customer service and had another one on the way in days! Finally got it a week later and went to set it up. It’s heavy!!! Open the package in its final spot. My wife and I have been tracking sleep with fitbits. They have both drastically changed for the better. My back doesn’t hurt when I wake up and my wife’s legs and back don’t hurt. Long story long, it’s worth trying. You have a 100 day guarantee and nothing to lose! Totally worth it and a great company too! It’s crazy comfortable!
