DEFINITION

Classification: 5/709

With solid filler (e.g., foam, spring, fiber):

(under subclass 706) Mattress having a confined gas in which the flexible container, in addition to a gas, contains a solid filler that provides support for a user of the mattress.

(1) Note. This subclass includes camping mattresses that can be rolled up or compacted by expelling air from the solid filler (e.g., porous foam) within the mattress, which the mattress, upon unrolling to its full size, will absorb air and fill up to its original uncompacted size and shape.
