Thanks for the info on how to remove the rear seat cushions, as I just finished replacing the rear struts on my 83 year old mother in law's TL-S. Without this information it would have been harder than it already was, as the lower seat cushion bolt is very obscure and buried under the cushion. I found that when putting the bolt back, it was easiest to wedge a flashlight into the area, thus giving light as well as spreading the cushions apart at the same time. The upper cushion is not easy to remove, especially with a 13 year old car with +230,000 miles. I used a crowbar (carefully) as a lever to push upward to dislodge the metal tabs from the plastic inserts; on reassembly I put the plastic inserts in the body panel first, then sprayed them with silicone; it went together much easier than it came apart!
