Hi winter1 and welcome to the Mattress Underground 
67yo female, 115#, 5’4", side and back sleeper. Looking for full size mattress. Shoulder pain started 9 months ago and I think it is caused by my mattress. Given my age and size, I am concerned about being able to lift the packages of any mail order bed if I went that route
Remember…as you already experienced with your extensive local testing (BTW… good job on that!) any mattress you finally choose will be unique to you, based on your Stats (height, BMI, sleeping position(s) and any underlying health concerns) and your PPP (Posture and alignment, Pressure relief, and Personal preferences). Thanks for providing your Stats! As you have a lower BMI, there are many mattress options that will provide support as well as comfort. You don’t say what type of mattress you currently sleep on, or what types of mattress you are looking at - foam? Latex? Hybrid? You can compare the Mattress Specifications You Need To Know to the Mattress Durability Guidelines to see how different mattress components hold up over time. You might also want to read the Mattress Shopping Tutorial to see how to find a great retailer. Have you narrowed things down
to the type of mattress you like? I would recommend a pocket coil mattress, as it’s lighter and easier to handle.
Do you have any suggestions for Northwest Indiana? I live between Gary and South Bend (46360 zip).
Unfortunately, with all the turmoil with businesses over the last few years, we cannot provide a geographic listing of manufacturers and showrooms; however a few Trusted Members of the site are located somewhat near to you:
-My Green Mattress has latex, foam and hybrid models in La Grange IN which is about 50 miles from you;
-Quality Sleep Shop is also in La Grange and has latex, innerspring, and hybrid mattresses as well as organic wool, cotton latex and other organic materials
-Mattress To Go is in Shelby MI and carries a variety of foam, latex and hybrid mattresses
-DIY Natural Bedding is in lafayette, they have latex mattresses and DIY components
you can call for an appointment to view their showroom
If you need to order online, the shipping should be somewhat less for these. As you have seen, most of the major mattress brands lack transparency in their materials, components and construction, and are staffed by salespeople who have very little information on the products they carry…I would not wish Chicago traffic on anyone! In person testing is
best, but if you need to order online, just make sure they have good return/exchange policies.
If you find any mattresses you like and have any questions, feel free to ask and we can possibly comment on them.
I wish you success in your search for a great new mattress!
