We bought a Natura latex mattress 8+ years ago. It was amazing. We originally bought the softer one and resold it ASAP so we could buy the firmer model. It has a great foundational layer of denser latex with some lighter latex on top and a very soft foam topper. So it feels very plush to the touch but has great support.
Unfortunately, these many years later there is now a big valley where I sleep (and a small one where my wife sleeps) with the continental divide ridgeline between us. Time for a new mattress. If I could find that identical mattress I would buy it again but that company is no longer around . . .
