Pacbed Original Bed in a Box Memory Foam Mattress Review

I purchased the PacBamboo King 11" Memory Foam Mattress. Read all the reviews and thought it would be a great deal, I have slept on the tempupedics and thought they were great. So trying to save a little money and after reading all the review I bought the Mattress. Well this thing is like sleeping on a rock, my wife and I toss and turn all night long and it is not what I expected at all. The bed has no give to it, maybe if we were each 300 plus pounds not sure. So now I'm looking for a new mattress, hopefully one we can get a good nights rest on.
