Review on Ultimate Comfort On-the-Go: Travel Pal Auto-Inflating Mini Lumbar Support with Lifetime Warranty by Dangelo Toliver

Many lumbar pillows are too big. A good support pillow follows the curve of the lower back. Not over/under the curve because that defeats the whole purpose. This pillow is true to size. Rolls up to a small size so you can easily put it in your pocket. It's easy to use. Unscrew the lid - another plus, the lid doesn't unscrew completely so you don't risk losing it - take a few breaths to fill it completely and tighten the lid. To deflate, uncap and roll up the pillow. Tighten the lid and the pillow stays rolled up for storage. Highly recommended for travel, especially for people with back problems.
