Seat question on 07 suburban

[smurfskier]

I have an 07 suburban Ls that I have put about 40,000 miles on. My question is this. My back has been getting sore after I am driving my truck. I drive about 160 miles a day 2 or three times a week. I am wondering if the seat foam may compress over time causing the lumbar to be in the right place. And just incase you are wondering I only way 150 lbs so I do not think it is a weight isssue on my part. Oh and my truck is an ls so the seats are the low end ones. Would a lt seat have better support? Any help would be appreciated.

I have the LS seats and I'm a big guy. I haven't noticed any abnormal changes in the seats. Not sure if there is an internal difference between the cloth and leather seats.
