Great mattress for the money! I slept on mine the day it arrived. I weigh over 300 pounds and this mattress supports my weight with no problem, and my 13 year old pug that sleeps at my feet. I don't really know where plush comes from, but I am more than pleased with this purchase. I weighs 77lbs, so get help if you need it. We'll see how well it holds up and I'll amend my review appropriately after a few months.
