Wow! That Zinus is cheap! I just bought a Ghostbed mattress which is about 3 times more expensive. I slept on it for the first time last night - it was really good.Here is the Sleep like the Dead review: http://www.sleeplikethedead.com/memory-foam-nitetherapy.htmlIt looks like it is decent (76% positive user rating) but has some outgassing issues, lack of support for larger people and couples which would make it a no go for us.
