Strong smell, long out gassing time.
I bought a two pack of jumbo PureLux  pillows at Costco for $10. The insert that came with it said it might have a slight, harmless chemical smell that will go away in 24 hours. Not!  The chemical smell was strong, and after two weeks of airing it out it still has a smell.  I have only napped on it for a short time, it seems nice to sleep on.  I will continue to air it out.  Be ready for a long out gassing period.
