Mattress. Queen Size. Used (like new). Marilyn Monroe Collection

This mattress was purchased from Mel Lastman's 'Bad Boy Superstore' in Toronto, Ontario. I'm listing it as used because I did sleep on it (using a mattress cover) for 1 week until I realized that it was too soft for me. There is some some light wearing at the foot of the bed (on it's backside: NOT sleeping side) shown in the pictures from me leaning against it for about another week (because I didn't have a chair at the time). Otherwise the mattress is in pristine condition and has been wrapped up in it's original plastic enclosure until resale. The mattress is on the softer side but it was too soft for me. The original MSRP was around 900$. I am selling the mattress ONLY (not box spring or frame with wheels) for 600$. It's a great quality mattress but lacks the support that I need.
