I asked if this product had an odor before I ordered it. I was told it does not, so I purchased it. I was specifically looking for one that did not have a smell and that would help with the transfer of motion. So... it does have a strong smell that the packaging acknowledges and says will dissipate. So be warned that you may have to allow it to air out for up to three weeks per packaging info. The smell does not bother my husband but my hair, sheets, pajamas and pillows all smell like latex. I am hoping it goes away quickly as it has been over a week. As far as comfort, it is really nice. Limiting transfer of motion is maybe a 2/3 out of 5.
