I'm glad you've found the NovaFoam to be your mattress of choice and Costco is a great place to get it. More importantly, your back feels great.
I too tested the NovaFoam, ask people whom have them, and read forums not associated with specific brands. I just decided on the Tempur-Pedic and couldn't be happier. It's just another mattress from many to choose from.
Foam mattresses are not the cure of all mattresses, like the notorious Z---- debate.
