I've been a big fan of memory foam for years, but haven't found a topper that's been exactly right... until now. The Sensus 1-inch topper is perfect for us. My husband prefers a firmer bed, and didn't like the feeling of sinking into a thicker topper. Even 2 inches was too much. This topper is very supportive, yet gives just enough "cush" to relieve pressure points. As other reviewers have said, it's difficult to believe that just one inch of foam can make that much of a difference.
Another plus: I was surprised (and pleased) that it fully covered our king-sized bed; it's actually just a tad over the dimensions of a king.
I only have one slightly negative comment. We received it the day before we left on a 6-day vacation. We unrolled and set it on top of the bed the day we left, but there was still a bit of an odor after we got back. It took about a week and a half to fully air out. However, having said that, it still fully deserves 5 stars. We've been sleeping great, and muscle and joint pain has been greatly relieved. I love this topper, and would highly recommend it!
