Hi GVSourkas,
The three factory direct manufacturers that are closest to you are …
Magic Sleeper and https://www.mattressandfurniturestore.com/ Pottstown (or Pottsdown), PA. Local factory direct manufacturer that makes a range of good quality and value mattresses including two sided innerspring mattresses and a number of latex and latex hybrid options. Family owned and good people. They also make custom designs and sizes and and they are also a member of this site.

Furniture Row®. Real Furniture. Real Value. York. Regional factory direct manufacturer. They make a range of mattresses of all types with good value (they also carry other brands which I would avoid). they may not carry their latex models (as of about t months ago but that may have changed).
https://www.verlo.com/ West Chester. Regional factory direct manufacturer. they also carry a wide range of mattresses of all types with good value. See post #17 here for some feedback about the West Chester outlet.
I would focus my attention on these three as it’s unlikely you will find better value or selection at other stores in the general area.
I purchased my adjustable base here and they have the best value that I know of. Serta is the Ergo with a few minor options added and the Reverie (which I purchased because I thought it was the best combination of features and value) is the manufacturer of the Tempurpedic base.
There are quite a few pages on the site which should help give you a few guidelines.
This article will help you avoid most of the lower value choices so you can focus more on the outlets which have better knowledge, service, and most importantly value. Local manufacturers almost always use better quality materials and sell for lower prices than the larger national brands which I would avoid completely.
Post #11 here has an analysis and review on the iComfort lineup.
Tempurpedic are high quality memory foam mattresses but are also significantly overpriced IMO compared to equally high quality (or better) mattresses made by smaller manufacturers.
I would also read the overviews that are in the mattresses section of the website to gain a bit of general knowledge about the materials and construction of a mattress as it will help you in your search.
This page has some guidelines that are connected to weight and this page has some guidelines connected to sleeping positions.
With stomach sleeping it’s especially important to make sure that the comfort layer isn’t too thick and that you have a firm support layer as well to prevent swayback. The Revolution is probably one of the least suitable mattresses for your weight and sleeping position and it would put you at real risk of worsening your back pain (your pelvis would likely sink in too far and hyperextend your back into a swayback position). Memory foam as a group is also quite tricky and I would seriously consider latex which is just as pressure relieving but far less risky for back issues. If you do decide to go with memory foam … I would use the highest quality possible (5 lbs and up) because with your weight a lower density memory foam will wear out much more quickly (including the 4 lb memory foam in the Cloud Luxe). Memory foam is also the hottest of all foams and regular polyfoam is cooler and latex is the coolest of all.
So overall I would take a little time to do some reading on the site … ask questions as you come across them … and put your focus on local manufacturing and definitely test the feel of latex as it would fit what you are looking for much better and would be far more durable than any memory foam.
