have had mine for roughly 2 years. The manufacturer I believe is Sarah Peyton. The top 2.5" features channels allowing heat to dissipate, then there is 8" solid foam underneath.
I occasionally rotate the mattress, it has not developed any body impressions. In my journey from 345 pounds to 290 it has been nothing but comfortable. Never being able to sleep on my back before, I now do so well, even while recovering from surgery.
I will never use anything but memory foam from now on.

Beggin' your pardon, it must have been the w@@t soup.
