I bought a mattress less than 3 years ago and within a year, I couldn't even imagine what made me buy it. I was wondering what sales pitch I heard and how I could possibly have been convinced it was a good idea....So I was on the verge of taking a hit on this mattress and unloading a newish, clean, mattress that was just sub par and literally uncomfortable. I searched overstock for a workable solution and bought this. It definitely made my mattress exponentially better as in I am not longer needing to replace it. I didn't have any issue with off gassing. Truthfully I didn't even smell the crazy odors I had read about and was expecting. Unrolled it in a spare bedroom forgot about it for a few days and then presto, in normal shape and ready to put on said bed. For me and my family it totally worked. I actually find the bed really comfortable now and am happy I didn't have to turn over a mattress that I had so recently purchased.
