(under subclass 690) Mattress in which the cover or ticking is especially adapted for quick access to permit removal, replacement, or addition to at least part of the inner core of the pad.
(1) Note. The cover or ticking usually includes separable fasteners that permit easy opening and closing of the cover or ticking.
(2) Note. Unlike the mattresses with distinct movable sections, where whole separate and distinct sections or units are removable from the mattress, a mattress placed in this subclass is not formed from separate and distinct sections or units, but is filled with a homogeneous "stuffing" material or the whole inner core is removable through the openable cover or ticking.
