DEFINITION

Classification: 5/699

Having waterproof or allergenproof outer surface:

(under subclass 690) Mattress comprised of material(s), on at least a substantial top portion thereof, that prevents the passage of liquid or spores, dust, insects, etc. therethrough.

(1) Note. A part of the top portion of the mattress may be made from an inherently waterproof material, may have been chemically or physically treated to be waterproof, or may have been provided with an integral waterproof covering portion, primarily to prevent the passage of liquids into or through the body of the mattress.

(2) Note. Removable covers or tickings that may incidentally be made from water resistant materials are excluded from this subclass.

(3) Note. The mattress top, or cover thereof, may permit the passage of gasses, vapors, and microscopic particles, such as bacteria, but will prevent the passage of liquids.

(4) Note. This subclass includes allergen-proof mattresses that in addition to preventing the passage of liquids into and out of the mattress, will prevent the passage of allergens, such as mite and mite feces.

(5) Note. Gas containing mattresses, which inherently prevent the passage of liquids, are excluded from this subclass.
