I've never done any seat trimming before, but I decided to have a go at it - the foam and additional Alicante turned up today, so why not?

I'd bought a driver's seat from Aeon in April - this is what it looks like:

The foam was quite large - larger than I envisaged it. I cut it to 38cm wide, and also in half (so about 4.5cm deep). This was one sheet - and I'd bought three!

I then cut the bottom to the right widths (after marking the widths at certain key points):

And also the top:

And using the remainder of the base, I made a top:

Which I then rounded off:

Next, I got the tub of contact adhesive, and pasted the two parts of the back together:

And after it had stuck:

Maybe I'd watched too many car restoration programs, but I decided to have a go at putting pleats in the base - it I made a mistake I would be able to cut a new one fairly easily.

So, I got a sharp Stanley blade, measured some slots 6cm apart, and then cut grooves into the base foam:

The first groove was at tha back, and I didn't do a very good job of it. However, the rest looked quite good!

I then cut out a square of Alicante, and covered it. Since this needed to be done fairly quickly, I didn't take any pictures of the top being glued in place. However, when it was done, I was fairly pleased with it.

I then glued the back, then the sides and finally the front to the underside:

By the way, I am doing this in the kitchen, because I was able to keep the back door open and take the fumes away.

Finally, I got some black thick board (like MDF, but a bit more flexible) and stuck it to the underside. Sorry about the exposure of this picture - the camera got a bit confused!

And as a last test, I put it in the seat:

There's a bit of creasing in the far back corner, but the back foam should hide a lot of it.

Tomorrow, I'll put some pleats in the back, and cover it with Alicante (assuming I don't run out of contact adhesive - the base took a fair amount of glue).
