Input: Consider Input: My best friend got this mattress before summer started and I've slept on it many times and I get the best sleep at her house. I asked for the mattress as a birthday present, I opened it on the 9th and as I was unrolling it i was starting to smell something musty but i thought it could be because it just traveled in a box for a few days. It's now the 12th and my ENTIRE BOTTOM FLOOR WREAKS OF SOME NASTY MUSTY SMELL. It smells like the bed is rotting. OH and the mattress I ordered is classified as a 6inch mattress but its measuring between 4 and 4 1/2 inches... 3 days later. Today is the first day I have done anything other than touch with my fingers or sniff. The bed feels very firm and if you sniff it you will want to gag. I've already filed through amazon that I'd like a replacement. I'm just puzzled how the mattresses could be so different. We both slept on her brand new, 6 inch, Zinus mattress less than 24 hours after she opened it but mine is like I picked it up off the side of the road. When I get the new mattress I'll edit my review accordingly.
