Drivers Seat Sag

I have a 2009 Silverado SLT with leather interior. I have noticed more and more lately that the drivers seat is more and more like sitting in a peach basket. The seat-bottom is sagged somewhat and the side of the seat bottom has cracked (the pleather) where it bulges towards the driver door. I get a loaned usually when I take my truck for service ans always notice how less firm my seat is than the loaner (after driving the load for a few days). My truck has about 55k mile and I weigh about 165.

 

Is anyone else experiencing this sort of failure? Is there a fix or a way of replacing or adding foam to the seat bottom?

there's a TSB on the leather seats, not really sure what it entails, search the forum and you might find it.

I've been only able to find a TSB on deteriorating leather seats in the 2005 model year range. There is also a more recent TSB for black cloth seats.

Felt the same issue in my '03 when new. Seat front bolster which should support shorter driver under their knees constantly put pressure on my long legged thighs. Very uncomfortable. No leather here, but...

I ended up threading strips of very dense 3/8" thick felt between spring and underside of existg padding.

Ended up installing 2 layers of the stuff. Big improvement.

I have definitely noticed sagging in the seats in my truck, which I'm sad to say is quite a bit older than yours. I did add the factory power lumbar device, which helped... but it seems to press on my back way too high, as if the seat bottom has in fact, sagged...

Unfortunately I have experienced this problem with several GM vehicles. My '07 NBS is starting to do the same thing. The worst by far was an '04 Impala where there is literally a pipe in the seat frame that crosses under the theighs. The factory foam broke down within the first 30K miles to where the pipe could be felt through the foam padding. GM replaced the spring base and foam under warranty but it fail again in the same mileage.

 

I found a decent fix is a layer or 2 of high density carpet foam inserted between the spring lattice and the seat foam. Most cases this takes the sag out of the seat. The Impala was bad enough that I eventually ran zip-ties through the small coil springs to limit their sag.

      2 speed transfer case optional now?

      By Chuck FB · Posted

      Yes, and also pulling heavy trailers or a large camper up steep grades as well as descending grades such as the more rustic off road camping locations and using engine braking with that low gearing as well as soft ground can just suck the power . I realize pickups these days tend to have an over all lower first gear ratio compared to automatic transmission pickups from years back so that has helped a lot in its ability in high range but there comes a point if in four wheel drive the torque runs out at the wheels, certainly with a gas engine. They don't put two speed transfer cases on pickups for a cool factor, they have a function if one needs that massive torque to the wheels that high range can't deliver.

      Notes 7/18/2026   3,400 miles on this batch of Mobil 1 Euro 5W40 since the GDI pump replacement. Alcohol runs very clean when ring seal is tight and the sump isn't getting hosed with fuel. Checked oil level at fill up today as is my practice and grabbed a white Kleenex to look at the color. What color?  I was going to change it but.....

      Gas Prices

      Interesting, I suspect I would have fueled up in Lee Vining as the day prior I would have filled up either in Laughlin or near there and maybe again before I entered Death Valley and once out the other side late that evening as I kept on driving into the night up near Lee Vining. Next morning I most likely fueled up in LV before heading over Tioga Pass into ( as I refer to it as "Yose .... Mite" 😁 ). And again that was 19 years ago but the price then must not have jumped out at me like the 5 bill a gallon theme of nutty cult hippy country Big Sir or head so far up their rear Aspen. I'd be curious to know where the highest prices are in the lower 48, I probably would not be far off to guess somewhere in Cali forn ie. Coldfoot and Prudhoe bay may have those prices beat but that is a whole other world up there and when prices are more normal elsewhere that is about what they can be up there I believe in no mans land. Anyway interesting that the 395 corridor is hosing people and the thing is, its tourist season and its not like there are a lot of competition options when driving up that highway from what I could see. Yup, big ole Boaterhomes and various other RV's ahead and behind me at the Yosemite entrance gate and they have to get their fuel somewhere.

      Those can be high, as well as the big California cities. The ones that will pop your eyes out are the 395 corridor on the Eastern side of the Sierra Nevadas. Lee Vining, $7.19 for regular and $8.89 for diesel is what the Google said right now.
