We’ve had this mattress for 3 years and I am already searching for a new mattress. After about 18 months the mattress started sagging in the middle. I was so excited to finally replace my old mattress I had for over 15 years. There were so many positive reviews and I did so much research. I couldn’t believe the sag in this mattress in only 18 month. On the search for a new one but I will never recommend this company.
