office chair neck support pillow

bought this on Amazon for $20 and it's too late to return. it works great on different chairs but unfortunately not on mine. very firm, super dense memory foam, removable cover for washing. it's literally brand new, I took it out of the packaging tried it on my chair, realized it didn't work and now we're here. excellent for everyday use. supreme materials and excellent craftsmanship ensure long-lasting durability.
