It contains rayon made from bamboo. This bamboo pillow can be fluffed easily by hand and with a little effort in a few minutes you can achieve a beautiful plump pillow. Grab the pillow and shake up the shredded memory foam inside. Use your hands to break up any clumps you might feel in the pillow. (You may notice that the foam has a slight smell, this is 100% normal for brand new foam and will dissipate quickly.) Now it's time to activate the memory foam! Toss the pillow in the dryer on low heat initially for 10 minutes (add a dryer sheet to help get rid of the new foam smell faster). If the pillow isn’t quite as full and fluffy as you like place it back in the dryer for an additional 5 minutes and repeat as needed.
