This mattress didn't even last us two years. It started showing signs of losing it's firmness within 6 months and the box spring frame broke after 1 year. My husband and I aren't big people (both under 150lbs) and the center is so saggy, even with a 3 inch foam topper, we've been opting to sleep on the couch the past few nights until our new mattress arrives. Very uncomfortable. I would absolutely not recommend this mattress unless it's going into a barely used guest bedroom.
