Corvette C5 and C6 Seat Rebuild

It is no secret that the seats of the Corvette C5 & C6 have a reputation for being less than satisfactory in the area comfort and support.

Over the last year or so, I’ve developed a repair process and want to share it with everyone. I wanted to see how it worked out in my car for a year and can say I feel its 100% better than OEM. There are two problems: The side bolsters from the factory do not have any support under them. So as you climb in/out of the seat, the outside bolster foam tears where it sits on the steel seat frame and quickly sags or goes flat. The steel wires in the center area cut into the foam and quickly cause the foam to sag and pinching around the hip area. I found this extremely uncomfortable after only 15 minutes.

Send me an email if you would like more information.

Here are the photos of a recent rebuild on my C6 seat. The C5 and C6 seats are basically the same under the cover. The information below is just the high points.

1. Unbolt seat.

2. Disconnect wires harness.

2. Remove seat belt.

3. Remove side controls, cut numerous hog rings, peal back Velcro, and until string

holding bottom seat cover then pull out bottom seat cushion.

4. Using spray upholstery contact cement, attach new fabric to the underside of seat foam. The center support wires cut into the foam quickly causing the bottom seat cushion to sag. This returns the bottom seat foam to its original position.

5. Using spray contact cement, attach new high density upholstery grade foam to underside of bolster area.

This adds the missing support under the bolsters.

6. Add jute pad on top of center support wires for additional firmness if desired.

This is optional and you should try this out before reinstalling the seat to see if you like how it feels.

7. Reassembled and Finished.

8. Finished and reinstall.

    I would like to add factory heated seats to my 2010 Grand Sport. Can anyone recommend a company who can help me add factory (not aftermarket) heated seats or the reason why it can’t be added?

    Thanks!

    I’m a big man hip to hip touch door to console,and obviously the seat is breaking down and the reclining mechanism broke so I’ve got the parts to replace and the electrical control panel has separated from the side of the seat (have part to replace) is it possible to add a small frame that connects to spring pan that will hide in side the bolster for extra support surrounding the elec,and recl,bolt to keep it from breaking your thoughts
