DEFINITION

Classification: 5/186.1

Surface:

(under subclass 400) Device wherein the support surface comprises a thin flat bottom structure composed either of assembled units connected together or of one continuous material; the structure being a substantially planar member which is so flexible as to require marginal tension for its support.

(1) Note. Wire fabrics are proper for this class (5) only when there is special marginal modification to adapt the wire fabric for connection to a frame or when the fabric is otherwise specially adapted for use as a bed bottom.
