    Having thus described my invention, what I claim as new, and desire to secure by United States Letters Patent is:An improved pillow comprising a closed casing formed by an outer porous sheet of woven fabric secured to an inner sheet of resilient, cellular, porous foam rubber, and a filling of feathers in said casing, the porous rubber and fabric sheets permitting air to flow therethrough while preventing passage of dust particles and protrusion of sharp points of the feathers through the sheets, the resiliency of the rubber sheet providing a yielding enclosure for the feathers and a cushion against said sharp points.
