I claim the ornamental design for a bed, as shown and described.
FIG. 1 is a front right perspective view of my new design illustrated with a portion of the headboard illuminated;
FIG. 2 is a front view thereof;
FIG. 3 is a detailed front right perspective view of an upper corner of the headboard of the bed, also illustrating the illumination; and,
FIG. 4 is a detailed front right perspective of the pilaster of the footboard of the bed.
The views of the bed not shown form no part of the claimed design.
The groups of diverging broken lines shown in FIGS. 1-3 represent illumination of a portion of the headboard. The dash-dot line in FIGS. 1 and 2 provides an unclaimed lower boundary of the headboard portion of the claimed design. The dash-dash lines elsewhere in the figures represent features and environment that form no part of the claimed design.
