Chicago Mattress Direct helped me choose the MST 101 Firm, best night of sleep Ive had in years! I couldnt believe the price, either. I am a firefighter/EMT with chronic back pain. I was able to sleep a full, restful, night of sleep... FINALLY! Dave was very knowledgable about his products and was able to make a suggestion based on a few questions. Thanks again guys! I wont go anywhere else, and I live over 4 hours away! well worth the drive!
