I was looking for a mattress topper for my fully firm mattress and came across this one. I've been using it only for a month now and I've had no problem with it so far. The mattress didn't take any time to inflate unlike most toppers which take around 2 days after opening which was a surprise and the colors were pleasing. It added a comfort layer and there were no depressions in the mattress after prolonged use and bounces back to its original shape. I feel well rested after waking up now which is the most important thing I look for while buying. All in all, a great product at a reasonable price.
