I purchased this mattress on3/25/2010. There is a manufacturer's label which states the mattress was made on 3/30/2010. I don't know who they got to make this mattreess but I actually had to go retrieve my old mattress from the pick-up in my yard. I tried it for 3 days. I tossed and turned all night, I sunk down in various places in the mattress and I woke up with worse back pain. I can not tolerate this mattress. I guess you get what you pay for.
