The Teeter Hang Up's F5000 Inversion Table is one of the simplest and best tools you can use to relieve back pain and correct poor posture. Inversion table therapy works by turning the table on gravity’s downward pull. When inverted, your body is placed in line with the downward force of gravity. This elongates the spine, increasing the space between the vertebrae, which relieves the pressure on discs, ligaments and nerve roots.The Teeter Hang Up's F5000 inversion table is constructed of high quality, heat treated carbon steel – a feature that allows this table to have a weight capacity of more than 300 pounds. The nylon mat is triple stitched and removes easily for cleaning. It is UL Classified 2601-1 for Medical Equipment in a Clinical Setting which requires a 400% safety factor. It also outperformed 6 of the most widely distributed inversion tables in product quality tests for structural integrity and durability.The Teeter Hang Up's F5000 Inversion Table Features:
