DEFINITION

Classification: 5/727

Sectional with regard to firmness:

(under subclass 690) Mattress having a body supporting section with a different compressibility or body support characteristics from another section either lengthwise, widthwise, or heightwise of the pad.

(1) Note. The mattresses in this subclass generally have a planar top supporting surface and generally provide a firmer portion for the heavier midsection of the human body, or in the case of a mattress adapted to support two users, one longitudinal section of the mattress may be less firm than the adjacent longitudinal section to provide a softer portion for one of the users.

(2) Note. Included in this subclass are reversible mattresses that have plural homogeneous layers of different support characteristics, one on top of the other.

(3) Note. Excluded from this subclass are inflatable mattresses that have sections inflatable to different firmnesses.
