Mattress Forum

As I was doing research online, I came across this awesome forum. I just purchased this furniture set from costco and it should arrive a in few weeks.

After some research I narrowed down my choices to

and

http://www.overstock.com/Home-Garden/Bodipedic-10-inch-California-King-size-Memory-Foam-Mattress-and-Cover-Set/1898764/product.html

and optional Foam topper (only $75, seems like a steal!)

Currently I am on a full size Sealy Posturepedic spring mattress and after sleeping on my brother's Bodipedic Foam mattress, I feel like it's time to upgrade. What do you guys think?
