Can I reupholster a chair myself?

Sure, you can do it yourself. First you'll first need to disassemble the cushion or the upholstered parts. Some dining chairs have seats that can be screwed right off and some are attached. If the padding is in good condition, you can cover the seat easily with new fabric. Either upholstery glue or staples are a simple way to attach the fabric where it is concealed. If you cannot dislodge the upholstered area of the chair, you'll need to neatly tuck the fabric around the edges and do something that will conceal the seams, such as roping or fabric beading.
