Where is a good place to buy a mattress?

I recommend the Original Mattress Factory. They manufacture their own brand of mattresses and sell them at their own stores, cutting out the middle man. When I was looking for a new mattress, I discovered that all the national mattress manufacturers only offered pillow tops on one side of the mattress, not both. Original Mattress Factory mattresses were the only ones I saw that had pillow tops on BOTH sides of the mattress, plus they were reasonably priced. Additionally, they have all their different mattress styles on the sales floor so you can try the fit and feel of each one.
