Hi Glenn1,
The first thing I would always suggest is to make sure you have read the post that is linked in my signature at the end of every post. The steps in this and the information it links to will give you the best odds of finding the best possible mattress for your specific needs and preferences. It also includes a link to the members here that sell online that I recommend (including SleepEz)
The better options and possibilities I’m aware of in the Pittsburgh area are listed in post #2 here
Hope this helps.
