This made my mattress feel new again! It was sagging and dipping! I thought my mattress was just getting bad after three years, but it was the old bed frame! Where it was breaking, the mattress was getting bad in those areas. As soon as we put this one, it was like magic! My mattress is firm again, and feels like it did in the beginning. With the old frame, I didn’t need to use my stool anymore to get on, and with this new frame I do again! I highly recommend it! Bought it on a whim, and it is fantastic!
