I purchased this queen size mattress 5 years ago. I see that its price went down $160! But this is not why I am disappointed. I realize that products do get cheaper over time. The mattress itself is where I am disappointed. It kept its shape and firmness for the 1st two years, but than it became mushy. now it keeps being compressed where I lay down, and does not return to its original form till days later. So basically, I get very little support from it, since it stays in compressed form all the time. I am much more versed today in foam technology, so I would have chosen, a firmer and thicker one.
