This is a neck and shoulder-soothing pillow (Brand: CALQS). It's a hot pillow designed to help you achieve comfortable sleep by warming your neck at a 40-degree angle for 15 minutes. *It does not have a massage function. It comes with a light gray cover (washed). Includes a brand new charcoal gray replacement cover. I used it for about a month, and while it's in very good condition, I think it has a slight indentation from when I first bought it. Please understand this before purchasing. It's still perfectly usable. This is a used item, so please refrain from purchasing if you are concerned. There are no instructions or box.
