We recently purchased our Serta mattress, and let me tell you, this mattress is AMAZING!!! We had another mattress we purchased new from a reputable competitor of Serta. After an entire year in agony, we decided to look at other options. That mattress was the most uncomfortable thing we had ever slept on. Sleeping on plywood surely would have been better. So, we decided to go with our Serta. I had forgotten what a real nights sleep was, but not anymore. My Serta is one of the best things that ever happened to me. It is so comfortable, does not make me sweat from the materials it is made from, gives me the best support in all the right places. This was the best decision we ever made. Good riddance competitor, Serta is the only brand for us from here on out!!!
