Made of environmentally friendly PU material, non-toxic and odorless, this back support cushion helps support the neck and back, releases pressure, and provides comfort for spinal support. Unlike standard lumbar supports, this ergonomic back stretcher is designed to help improve sitting posture. Use for 15 minutes at a time to help relieve tension and support muscle relaxation. It may assist with discomfort related to muscle strain, nerve pressure, disc issues, sciatic discomfort, and tight muscles. While stretching and massaging the lower back, the PU cushion helps reduce pressure on the spine, and built-in massage points provide gentle spinal massage for enhanced relaxation. Designed for users of various ages and fitness levels, it can help promote flexibility and comfort during use.
