Bought it new less than a year ago at Mattress Firm. No stains of any sort, very clean, firm but soft. No Smoke environment.
Mattress is about 12" thick and the box springs are 9" thick. Also have the bed frame on rollers.
This mattress is damn heavy so you'll need two strong men or boys to move it.
I do have the mattress wraped in thick plastic and that makes it a little easier to load.
I paid over $400 for the set.
Sorry no photo's because I have it stored in a corner and ain't pulling it out by ...
