Hi Catcat1128,
There are a lot of mattresses on your list that I wouldn’t consider either because they use lower quality foams or because they have poor value.
A mattress is only as good as the materials inside it and without knowing this information (including the density of any memory foam and polyfoam inside … there is no way to make meaningful comparisons with other mattresses, estimate how durable it may be, or know it’s real value.
Post #10 here may be helpful and will give you a step by step process that can lead to finding a mattress that meets your needs and preferences and will have better quality/value.
While Plushbeds uses good quality materials and has “better than average” value … there are some very similar mattresses with more options that have better value in the list of our members who sell online in post #21 here. These members are all very good at helping people make the best possible choice and many of them provide exchange options after a purchase if your online choice isn’t quite right.
On a more local basis there aren’t a lot of good options and these would require more research to find out whether they are willing and able to give you meaningful information about their mattresses and are one of the “better” local outlets (along the lines of this article). I’ve included the brands they carry that may have some better value (depending on the models they carry and their willingness to give you the layering information).

Further away there are some better possibilities in the Baltimore/Washington, DC corridor but these would involve a longer drive.
List centered on Washington, DC is in post #2 here
List centered on Baltimore, MD is in post #4 here
There is some overlap between these two.
Other than a longer drive or a good “discovery” from the local outlets I listed … your best options if you are comfortable with it may be an online purchase from one of our members from the list I linked.
Hope this helps and feel free to post with any more questions along the way.
