Build a motorcycle seat

Step 7 Add pad

I used carpet padding. We have way too much of the stuff, and rather than watch it become a condo for more spiders, I figured I'd use some of the excess. I could have grabbed more foam, but I figured ol' ironbum would be fine with a little more than one layer. I was wrong. Use at least two full layers.

Cut your pad to roughly fit your seat, with overhang on all the sides possible. Sharp corners to the inside of the thigh aren't fun. You want to pad those.

I stapled my foam to the plywood in the back to hold it roughly in place while I taped. Don't count on stapling everywhere with your handheld staple gun. Since you are going to be brighter than I was and use two full layers, you will need to glue your second layer to your first. Then cut two strips of pad as long as your seat and about two inches wide. These will go on either edge to help ensure you don't feel that sharp plywood edge. Ideally, they should cover the corner and extend far enough in so that your hipbones sit on them. Trust me on this, you want the bit your hipbones rest on to be higher than your tailbone's resting place.

You can just set these strips in place.
