I was suffering so much from stiff shoulders that I bought this online, hoping for some relief. It was so amazing that I bought one for my family too, but since we shared one, this one is extra. It's a great product that can be used anywhere, on the bed, sofa, or floor, and it's very light. 【Product Description】 ★ This is a neck relax pillow. ★ It's designed to gently reshape your neck into a normal arch just by lying down. ★ Use it for about 5 minutes a day, up to a maximum of 30 minutes. ★ Six protrusions apply acupressure to the muscles around your neck, spine, and shoulder blades. It feels like you're being massaged by a chiropractor. Material: EVA resin Product Dimensions (Length x Width x Height): Approximately 23 x 21.4 x 12.4 cm ■ Shipped in simple packaging.
