My sleep quality has improved.

I had a very firm latex mattress for almost 20 years. My sleep quality had degraded during the past few years but I cannot be sure of the reason. My old mattress may have been partially to blame. My new Saatva Zenhaven latex mattress is slightly less firm than the one it replaced and I was concerned that this would be a problem for my back. However, my sleep quality on the new mattress over the past few months has been excellent. Also, I've detected no odor from the latex material.
