Fill the void of space behind your head, neck, or back on your recliner or almost any seat with this highly-adjustable and customizable pillow. This is a SUPPORT device and is NOT soft or cushiony. It's primarily for FIRM support, although you can create softer support by adjusting the filler OR removing excess filler. Patented design allows for custom adjustments on-the-fly. Rest your head against the bulbous (top) end of the pillow for firm support for alert activities like reading, driving, conversing, or watching television. Or use the concave (bottom) end of the pillow behind your head or neck for more relaxed support, like resting or napping. For lumbar support, use the concave end of the pillow for support that’s shallow at the center and flared at the sides, like a traditional lumbar pillow. After selecting your pillow-end, you can further customize the support by transferring the loose filler to make it more or less full. Once you position it, Body Prop stays in place because of the non-skid backing, along with the counterweight effect of the pillows. If you experience excess slipping, ensure the nonskid backing is clean and doesn't have lint on it. Also ensure the weight of your two pillow-ends is nearly balanced. Surface-washing is recommended, although it can be gently laundered if the loose filler is removed. (There is not an internal casing for the filler because that would make the product too firm and more difficult to adjust.) Two sizes to choose from: Classic (26"), and Long (38"). Body Prop is the redesigned and re-branded version of our original products, Headbone and Backbone (collectively called Bone pillows, which are discontinued and sold out). Manufactured in Maryland, USA using Silky Minky fabric from Korea. Non-skid (PVC coated knit poly) and zipper made in USA. Package printed in USA. Buckwheat hulls from USA. One-year satisfaction guarantee. This product is sold by and shipped from the inventor.
