ABSTRACT:
Lobed resilient lumbar pillow adapted to support the lower back of a person either sitting or reclining against a suitable article of furniture. The pillow has two integrally formed side lobes extending laterally apart from one, and another integral lobe extending upward from the midpart of the top of the pillow. Along its vertical bisector the top lobe surface is preferably recessed notchlike from its edge to accommodate a user's spine. The pillow is filled with resilient contents, such as elastomer, fibers, gas, particulates, or mixtures of two or more thereof, or partly filled with liquid, so as to flex to fit a user's spine.
