Arrived quick, packaged perfectly. Absolutely No Odor, unrolled and puffed up within 10 min.  Popped it on bed and made a huge difference with my new extra firm mattress.  sealyChill  is not warm to sleep on.  Soft but not to soft. 2” was perfect.
Sleeping much better is. TY Wayfair and Sealy !  I would recommend this.
