When you take your office space and add decorations and a personal sense of style, you make that space feel like your own. Turn your office chair into a seat of inspiration after you learn how to sew a slipcover for an office chair -- in a few steps. Cover the back of the chair and the seat, or just do the back by itself; with basic sewing skills you can make a slipcover for your desk chair that will have all your co-workers feeling jealous.
Measure the height and width of your chair back; if the chair back has thickness to it, divide that in half and add that to the width measurement as well.
Add 1 inch to your height and width measurements, and then cut two pieces of home decor-weight fabric to match these measurements.
Fold up the bottom of each piece of fabric by one-fourth inch toward the wrong or back side and press, then again by another one-fourth inch, and press again. Use straight pins to hold this hem in place, and sew along the bottom edge with a straight stitch.
Position the two pieces of fabric together with right sides facing, lining up the bottom edges you just hemmed. Sew a straight seam around the top and sides of the pieces, leaving the bottom edge open entirely. Position your straight seam approximately one-half inch from the edges of the fabric.
Clip the corners of the fabric at the top, outside your stitching line, so that you don't cut your seams. Turn the fabric pocket you have just made right side out, and slip it down over the back of your office chair.
Remove the base of the seat from the seat frame, if possible. Sometimes you can unscrew the seat underneath so that the seat cushion comes off; other times this isn't possible, so leave it as it is.
Cut a piece of fabric that is approximately four inches wider and taller than the dimensions of the seat cushion. Drape the fabric over the seat cushion, and center it.
Wrap the edges of the fabric around the seat so that the edges come underneath the cushion. If you have removed the cushion, the easiest way to do this is to put the fabric right side down on a table and then place the cushion upside-down on top of it. If you keep the cushion in the chair, then just turn the chair upside down as much as you can to facilitate this process.
Staple the edges of the fabric to the underside of the cushion using a staple gun. If you don't have a staple gun, you may be able to use sturdy glue for this step or even heavy-duty duct tape. Secure the edges of the fabric all under the cushion, and you will have a new slipcover for both portions of your office chair.
