The Essence of Bamboo Pillow is as described on the product description page. This is a premium stay cool bamboo rayon covered pillow. Bamboo is a naturally dust mite free, cool, strong and absorbent fiber. The inside of the pillow is down alternative fiber. It is machine washable. I like having different types of pillows around for different things. I have memory foam, shredded memory foam, down and fiber. I like different pillows for head support, lumbar support, to prop my legs, etc. This one expanded nicely and will be great for lumbar support. I find it a bit hard for my sleeping comfort but find it great for many other activities. I love that it is made in the USA. It came all wrapped up like a cocoon, which I found interesting so I taped the unwrapping. It really got larger as it was exposed to air. I purchased this queen size Essence of Bamboo pillow with a promo code.
