This product acts just like the Lumbar Roll except that this roll is 4" (inches) in diameter unlike the Lumbar Roll that is 5.25" (inches) in diameter. The Mini Roll is perfect for smaller people and can be used for slightly less aggressiveness for any size person. It is also a perfect travel pillow and is a perfect substitute for a cervical roll when traveling or away from home. The Rucken Mini Roll is very versatile and convenient in any application whether relaxing or for therapeutic use and workouts.
The foam used is Vita Ultracell Polyurethane foam wrapped in plastic to prolong the life of the foam and product for years of proper compression and resiliency.
