Abstract
Abstract A self-balancing support means particularly adapted for holding a book, magazine, newspaper, or the like, to which are attached adjustable and removable bags containing fluent material which may be adjusted to various positions to balance and hold the support at various inclinations to the horizontal, movable biased means provided on the support and releasably engageable with a book, magazine, newspaper, or the like, so that the pages of the book, magazine, or the like may be turned. A modification of the support means provides a configuration thereof better permitting it and the balancing means to rest on portions of the human body with facility, and in desirable position for reading the material supported thereon.
