I have had my firm Tempur-Luxbreeze for almost three years.. It is the BEST investment I have ever made for my Fabulous nights sleep ..I look so forward to sleeping on my mattress every night.. The firm mattress helps me relax more then the softer levels ..It has been so worth the money ! People talk themselves out of having the best due to price , they live to regret it..I also got the Tempur sheets to fit the mattress and that makes it easier to change them.This mattress is so cool in the summer.. I have NOT had "sweating" since sleeping on this mattress ... The Tempurpedic policy for return is excellent but in reality, I don't think there are that many returns..This is a longterm investment with GREAT rewards for a much better sleep, less aching pain, more enthusiasm for activity during the day and waking up grateful for the beauty of a restful sleep.... Thanks Tempurpedic!!
