I purchased a Serta Tamron Plush King mattress because I was waking up in pain due to my back and neck. I decided that I needed to switch my mattress. Prior to purchasing this new mattress I had a Beauty rest Plush King Mattress. Don't get me wrong I loved it however over the years it became too soft for my body and what it was going thru so that is why I decided to give this mattress a shot. It is really comfortable and is doing wonders for my back and neck. It is so nice to wake up after a yr and feel good to be in your own body!!
