Bought it mm 3 months ago I say, expected the topper to be softer after some use - pretty firm still , regardless my cuality of sleep has improve since I got it.
I have one of these on our king size bed and it incredibly comfortable. We had to buy a very firm mattress because of hubby's weight and back problems. This topper adds the perfect amount of cushiness that we both love. Our son has one on his bed too. Loves it.
I bought this topper after I was bed ridden for days, my mattress was painful after so many hours, I bought the topper instead of a mattress due to funds, It was the best investment to date. I don't feel any of the old mattress. Thank you Tempurpedic
