Query: Better sleep

My wife and I have used a similar mattress topper that was a 2-inch that lasted for about 3 years. We thought if that lasted 3 years we should try a 4-inch. That only lasted about 1 year but was great for the first few months. We then decided to try the 3-inch to see how that works for us. We have had this 3-inch topper now for about 3 or so months and I sleep very well. We both agree that for us this is better than the 4-inch topper and comparable to the 2-inch topper we had a few years ago.
