The Comfort Test showed me mattresses that did not match what my preferences are. Why would that be?

There are some remote results from our Comfort Test that could be at opposition to your stated preferences. For example, maybe you prefer firm mattresses but our Comfort Test recommended C-10, which is our softest construction possible. In this rare case, you likely also stated that you sleep on your side or stomach.
Our Comfort Test is designed to weight the answers to the test, meaning that from our research, a side or stomach sleeper would benefit more from a soft mattress, even if they think they prefer a firm mattress.
In this situation, we invite to give our recommendations a try. We believe in our research, foam experience, and our Comfort Test. If we're wrong, which is certainly possible, we'll bring you out replacement Comfort Layers for your mattress free of charge to make things right.
