Received the harmony lux anchor island firm a few weeks ago and have been having the best , most restful sleep I've had  in a long time .  I wake up feeling rested , refreshed and the best part with no back or hip pain . Husband sleeps on it as well but I don't feel him move throughout the night thanks to the motion isolation technology, he absolutely loves it as it has helped him with his back pain but also because this mattress feel much cooler than our previous mattress. Overall this feels like a great quality mattress and I definitely recommend it to anyone on the market from a new mattress.
