Reviews mention stinky smell. That is right on! That is the only reason I gave this a "good" rating instead of excellent. Left ours in very cold garage where gets lots of ventilation for a week. Brought it in, as it got warm got rather stinky again - took away my breath! However, after a lite spray down with Febreze and letting it lay on top of bed to dry for 2 more days; we got rid of the smell. Febreze is an amazing product and I think if I had used it at the beginning the airing out process would have moved along a lot quicker. Very comfy - fixed a problem with older mattress with indent in middle.
