The old mattress in my mother's guest room was a lumpy mess. My wife complained every time we went to visit. My mother would never replace the mattress so I finally decided to replace it for her. I searched for hours to find the right mattress, I read and read reviews until I found this one.My wife likes firm mattresses and I like soft mattresses so finding one we both enjoy was a challenge. I finally settled on this mattress and I could not be happier. Mywife complains back pain after childbirth, she said this one makes her back relief a lot. And we both  are heavy people, this mattress supports us fine.The only problem is now I like the guest bed at my mother's house better than my own. I highly recommend this mattress, I love it, my wife loves it. We will soon be getting one for our house. I highly recommend this mattress and you should definitely give it a try
