From the Coop website: “Finally! A nappable throw pillow that’s as comfortable as a bed pillow. We created a truly blissful solution to flat, sad, and uncomfortable throw pillows. Lined with a solid sheet of gel-infused memory foam and filled with an adjustable cross-cut memory foam and microfiber blend, ours is the first throw pillow that won’t fall flat.” This is one throw pillow insert, 18x18 inches.
