We bought the midnight elite to replace an 8 year old temperpedic. Costs drove us to look around and the research had Helix checking all the boxes. Great reviews, good information on the products, variety of options, warranty, made in the USA and the cost was thousands less than others. Very pleased with our purchase. It came in two boxes and was ready to sleep on that night. (About 5 hours of expanding). Be sure when removing from the packaging that you have it on the box frame or where it is going to be used because it is a heavyweight.
