I have a Purple Restore premier. It's top of the mid tier of their mattress (Also a hybrid since I'm over 200LBS) and it was the one that was for us. In my opinion you need to let your body tell you what mattress is for you. and the base will most likely work with it.
I just want to know if I should go with Capser or Purple smart base. I'm getting a purple mattress but the casper bases are cheaper and I think the zero gravity seems a bit better with Casper
