Here are the seats for the 1967 Cessna 150G. These are original equipment seats which have been previously upholstered with an aftermarket upholstery kit.

It appears as if this was installed over the original cushion supports which have since further deteriorated.

Disassembly begins by first removing the seat back screws and seat backs. Next come the upholstery.  The seat upholstery is installed using "hog rings" sometimes known as "steel staples".  The first pic here is an out of focus photo of myself. I can't stress enough how important it is to use heavy wire or bolt cutters for this and wear protective safety gear. These things are so sharp they'll literally tear your hide to pieces and I'm not kidding.

Here's what was causing the vinyl upholstery to rip on the outboard corners. The seat frame extenders had pulled loose at the attachment screws allowing the sheet metal extenders to flex and move back and forth. This, in turn, caused the cutting and other wear on the fabrics. This will be remedied after we install the new cushion supports and re-install the seat back extenders with some new screws and make sure we get them on the frame tight.

Here they are now all ready to begin the cleaning and refinishing of the frames.

The frames are shown here disassembled and the cleaning begins. The rollers are removed and all the excess dirt, grease, lint, etc. is washed away leaving the clean parts to inspect. The frames are primed with epoxy primer and then finished with the Jet-Flex Grey Beige low gloss interior finish.

Next, come the cushion supports. After attaching to the seat frames, the new foam cushioning is fabricated from medium density base cushioning graduated to soft density for the top layer. The new leather upholstery is now fabricated using 1/2" additional quilt cushioning. This assembly is now installed over the new cushion supports & refinished frame.
