I'll add my experience with the LSEAT covers as I recently completed installing them on the two front seats of my '96. My factory seats weren't too bad but the leather was tired and the foam on the sides of the seats next to the doors was a 'deflated'.
I ordered the LSEAT sample swatch and while I was tempted to spice things up a bit with Burned Orange or Sapphire I decided to match the factory colors and chose 'Bisque'.
I ordered the replacements for the two front seats and it also came with the the armrest leather for the doors and center consol which was nice. I also got the set of hog ring pliers which was essential to do the project. Once I got the leather in the mail I decided to see what it would cost to have an upholstery shop install these covers for me here in Seattle. I stopped by Rick's upholstery which has half a C2 Corvette embedded into their sign and they wanted $800...per seat. Well I got out of there as fast as possible resolved to save some money. I was already $350 in the hole for the covers and spending another $1600 seemed crazy. I need my money for real upgrades.
Removing the seats is fairly straightforward, just remember to disconnect the electrical connections. I also had a problem with my motorized seat gears that I replaced with the Gamiviti replacement parts. Unfortunately the threads for the outer caps were a bit stripped and thus would pop off when I moved the seat forward or backward I solved this by using some epoxy to hold them in place. I didn't go wild with it and hopefully it could be broken loose if necessary in the future.
The main thing that I wanted to share was how I ended up fixing the aging seat foam. I bought some high quality upholstery foam from my neighborhood fabrics store, foam adhesive, and an electric carving knife off amazon and cut out the chunk of bad foam.
Here is the new foam in place and carved.
While most may call this good I worried that repeatdly entering and exiting the truck would cause the new foam to be pulled away from the old foam and I thought this may be an issue for the long term. My solution was to take some old cheap soft flannel PJs that my ex gave me and create bandages that I glued to the foam using the foam adhesive. This way the border between the new and old foam would be bridged and would hopefully prevent the two from pulling apart in the future.
While it doesn't look too pretty now this will obviously all be covered up with leather, and the soft thin flannel wont transfer through by sight or touch.
Another change that I made involved bolstering the bottom layer of the seat foam where it rests on the seat springs. The factory foam sits on a bed of consolidated fibers that provide a foundation to distribute the weight onto the springs. There isn't much in the way of support though and after 20+ years this foam could use all of the help it can get.
I first went to the local sporting goods store and bought the cheapest foam yoga matt without any texture to the foam. I believe this was around $15. I then placed a layer of foam into the lowest areas (when seat is upside down) as shown above. There are areas of the seat frame that fit into these recessed but we won't prevent that by adding this foam.
Next I basically covered the whole bottom with another layer of the yoga mat.
Next I added a layer of recycled fiber moving blanket which is about 1/8" thick. I think this is available at uHaul. This provides a nice new foundation for our yoga mat before transitioning to the aging foam while helping to support our new foam patches. I thought that adding this may make it tougher to install the seat bottom leather but it didn't make the cover too tight. I probably could have added another layer without issue. Without it I'm afraid the leather would have been too loose on the old foam. Once its complete and you sit down for the first time your derrière will thank me...Iasda
