How to reupholster car seats yourself
Reupholstering a car seat is within reach of a patient amateur with a strong sewing machine. Expect your first seat to take a weekend. Here is the whole job, in order.
Safety first
Many modern seats contain side airbags, occupancy sensors and heating elements. Disconnect the battery as your workshop manual describes before unplugging a seat, and do not re-cover a seat with a side airbag yourself: its cover uses a special tear seam that must open exactly as designed. Leave those seats to a trimmer.
Tools and materials
- a heavy-duty or walking-foot sewing machine, and bonded nylon or polyester upholstery thread;
- hog ring pliers and hog rings, a seam ripper, sharp shears, tailor's chalk;
- thin scrim foam and spray contact adhesive;
- paper or card for patterns, masking tape and a marker;
- a steamer or a heat gun on low;
- the new cloth and, for bolsters, leather or vinyl — see how much fabric to order.
Step by step
- Remove the seat. Unbolt it, unplug connectors, and work on a clean bench.
- Photograph everything. Every clip, every hog ring, every seam from several angles. These photos are your manual when you put it back together.
- Take the cover off. Remove trims and knobs, cut the hog rings, slide out listing wires, and ease the cover off the foam.
- Label and unpick. Mark each panel (cushion centre, left bolster…) and its top edge, then unpick the seams.
- Make patterns. Trace each old panel onto paper. The old cloth has stretched, so true up the lines and restore a seam allowance of about 3/8 inch (1 cm) where it has frayed. Mark the grain direction and the centre line.
- Lay out the cloth. Plaid is cut on the straight grain and never turned sideways. Place the centre line of each seat panel on the same band of the check and mirror left and right seats. Lay out every piece before cutting anything.
- Cut and back. Cut the panels, then bond thin scrim foam to insert panels for body.
- Sew. Assemble panels in the reverse order you unpicked them, add piping if the original had it, and topstitch seams flat.
- Fit. Warm the cover slightly, pull it on evenly, put listing wires back in their channels, and hog-ring at the original points. Work from the centre outwards.
- Refit the seat and check belts, adjusters, heating and sensors before driving.
Mistakes that give a DIY job away
- a check that jumps at the seams — see matching the check;
- wrinkles from uneven pulling — fit from the centre, not from one side;
- furniture fabric that fades in a summer — use cloth meant for car interiors;
- running out of cloth — a second batch may not match the first.
DIY or trim shop?
A simple bench or a flat bucket seat is a good first project. Heavily bolstered sports seats, airbag seats and leather work are where a professional earns the fee. A common compromise: you remove and refit the seats, the shop sews the covers.
Choosing a pattern: start with houndstooth vs tartan, then order the sample set ($19).
