Hi RJ29,
The better options or possibilities I’m aware of in and around the Chicago area (subject to making sure that any mattress you consider meets the quality/value guidelines here) are listed in posts #2 and #4 here.
As you know Quality Sleep Shop is one of the members here which means that I think very highly of them and I believe that they compete well with the best in the industry in terms of their quality, value, service, knowledge, and transparency so you are certainly heading in a great direction and I’m looking forward to your comments and feedback after your visit.
