Inflatable Lumbar Pillow
I often recommend that patients use a lumbar pillow whenever sitting for prolonged periods. The inflatable McKenzie Airback is portable enough to bring to the theater, performances, and long train trips without being too conspicuous. There is also a self inflating version found below.
