The OEM carpet does not run fray so you can just cut a plus sign the size of the bolt. I marked and cut the holes before I put the bolts in. That way the carpet lays flat. Holes are tiny and the whole process could be easily reversed.

All the brackets are double bolted in the rear and single bolted in the front. The seat does not have a headrest but neither does the center rear seat. This has become a favorite seat for the kids as they have a clear view out of the front and sit up a little higher. Tall adults fit it too but you are 1 inch closer to the ceiling and your knees are 2 inches further forward than the captains chairs. Driveshaft hump is fine for kids as they use it as a footrest but adults will find it comfier to share the footspace with the adjacent captains chairs rather than keep you feet on the hump.
When used as an arm rest, it's just about perfect height and similar to the front. Probably a little more cushion to it. I had to remove the oem arm rests and still have the holes unfilled. You can barely see them but I’ll probably cover them soon with a bit of plastic.

Overall project was a 2/10 in difficulty and a 10/10 in functionality and a 8/10 in asthetics. The vehicle has white stitching in dark black leather and this jumpseat has black stitching in black vinyl. The black plastic of the jumpseat looks a little cheaper than the rest of the suburban and I would prefer to have had softer foam and matching mahogany leather but it does not exist. No special tools were required other than a cheap drill bit and a bit of oil, I spent a lot of time making sure the height and angles were perfect. It took me about two weeknights after I had ordered all my parts. Using this post, two sets of deep sockets, two 3/8th ratchets and a drill, I could install it in under 2 hrs.
