When I opened the packing the (lavender) odor was super strong for 2+ full days and for a couple more when I turned the bedding back at night.  Also, I had no idea that I would need to leave it laid out flat for 48 hours before I put it on the bed.
Finally, it’s so soft it seems to curve in like a dog-bed rather than support my curves.  It’s creates or holds in body heat too, so will be nicer in the cooler months.
