Came rolled up in box. Struggled to remove both pillows from the “see through wrap.” Once opened, they began poofing up slowly while being laid flat. After 24hours, they remained flat so I followed Cooksey’s recommendation and placed both pillows in the dryer for about 15-20 on low heat. They billowed up nicely. The grove in the pillow helped me to sleep comfortably while shifting my head from left to right. It’s not as firm as I’d like it to be, but since it is comfortable to my neck-I’ll keep these pillows. No odor from the plastic they were wrapped in.
