Input:
I bought this mattress for my 3 year old granddaughter and me to sleep on at a family gathering.  My pregnant daughter set it up and she and my 2 year old granddaughter slept next to us.  Strong fumes coming from the mattress woke us up during the night.  The baby moved off the mattress and slept elsewhere in the room.  The next morning I read the fine print on the bottom of the box.  It warned that this bed could cause cancer, birth defects, and reproductive harm. Made in China.  I called Coleman and talked to someone who wouldn't comment on my situation but said that someone from the company would call me within the half hour.  No one called.
