I've got the rain x silicone blades. They have been great now for about 2 years. Crazy expensive though

It's latex (rubber) sap straight from the tree. It is whipped into a foam poured into a mold and baked. It is supportive and springy/bouncy unlike memory foam, but it still contours to your body. The latex foam doesn't break down and sag like memory foam from what I have read. I have only had my mattress and pillows for about 2 years, so I can't really comment much on the actual longevity. Also I have never had a solid latex pillow only shredded so I can't say much about those.

Very breathable and not anything like memory foam. Latex doesn't sleep hot like memory foam, and latex actually has bounce to it unlike memory foam.

Natural latex pillows. I have a shredded latex pillow that came with my latex mattress and it's the best pillow I have ever had.

We love ours. We sanded, stained and lacquered it and it is beautiful and built incredibly solid. We needed something solid for an insanely heavy latex mattress.
