The ornamental design for a chair, as shown and described.
FIG. 1 is a right front perspective view of a reclining chair showing my new design. A left front perspective view is omitted because it is a mirror image to the right front perspective view.
FIG. 2 is a left side perspective view thereof. A right side perspective view is omitted because it is a mirror image to the left side perspective view.
FIG. 3 is a front view thereof; and,
FIG. 4 is a left side elevation view thereof showing the chair in a fully reclined position.
A right side elevation view is omitted because it is a mirror image to the left elevation view.
A bottom view of the claimed design is unornamented, and thus, has been omitted.
A back view of the claimed design is unornamented, and thus, has been omitted.
Portions of the chair not shown, such as the reclining mechanism, form no part of the claimed design.
