Local mattress company in the greater Detroit area

i live in a suburb of Detroit and am looking to visit manufacturers near me. Any advice?
I am interested in an innerspring coil mattress for a platform bed. I would like very good quality at a fair price. I am not interested in pillow top or foam or gel.

Hi s-sue,

The better options or possibilities I’m aware of in the Detroit area (subject to the quality/value guidelines here) are listed in post #2 here.
