Rebuilding seat.

So after weeks of trying to trade a 2004 GSA low seat for a standard or high I got impatient and decided to cut into the seat and build it up.

For anyone with a low and needing to add an inch or two it was quite simple IMO the 2nd time around as the first time I tried to use spray foam to fill in any gaps. Let's say spray foam is not fun to deal with when building a seat lol.

I took 5lbs foam that I got from Home Depot at $0.25/yrd to raise the seat and build up the sides. 3M heavy duty adhesive spray for contact and a hack saw blade and scissors to trim.

I did not have a sufficient nail gun or grinder attachment to smooth out the sides and reshape it all the way like I would have wanted to but it's simple enough if you have the tools. I did not so I took it to a shop for them to take out the minor humps, stetch vinyl, and staple.

Overall with the upholstery shop doing the finish it only cost me $140 and I got to keep the BMW seat foam for my top base which I actually think is really comfy.

Added about 2" in the front and 1.5" in the rear which was perfect for me to be on the balls of my feet and with the SM lowering pegs I am soooo comfortable now.

However, next time I do a seat I will use more of a dense foam to fill I'm any gaps as opposed to the 5lbs foam I used. While it works it's tedious to constantly cut strips and layer it while a harder more dense foam you'll be able to cut and shape the whole section in one piece.

A couple of tips.

If you are building the seat foam based on the old seat pan use some plastic to lay on the pan, makes it easier to work with, if you get glue etc on it. When you are done you can just trim the plastic and mount it all between the seat pan and the cover. Avoids overspray onto the seat pan, bike etc.

Memory foam may be OK for a very thin top layer, but never use it to build the entire seat. It is too soft. If will initially feel really good but as you ride down the highway you slowly will sink down to the seat pan. The firmer foams are always better for building seats.
 
It's comfy for long distances but it's slightly too wide/tall. I have since ordered a new foam and cover for the seat.

I didn't realize I could just order the normal height foam and cover for less than $200 which even after my initial investment still saves me over $100 from any upholster.
