I was wondering if anyone else has any discomfort issues with the driver's seat cushion? It feels like something has collapsed in the right rear part of the seat and my hip is being driven into the right side bolster. I just hit 5000 miles and during my visit to get the tires rotated/oil changed, I told the service adviser about my issue. They took the seat apart and reassembled it. It doesn't feel like its collapsing anymore, but there's still a lot of pressure from the bolsters. I don't think it's specific to my GLK as I had the same issue with the seat in the 2012 GLK loaner they gave me over the weekend. Anyone else find the bolster's a little too narrow?

Co you have the lumber support blown up too much? Or too high?

3.5L

I'm going to step out on a limb and say that it might be differences in body shape, size. My wife and I are probably a little smaller than average, but so is the GLK 350. We have done up to 11 hour days in our 2012 GLK and arrived at our destination without discomfort. Tired, but not sore. Of all of the many vehicles I've owned over the past 45+ years, our GLK has been by far the most comfortable.

I'm 5' 10" and 150 lbs. I've hauled a 6' 3", 250 lb. co-worker in my GLK and he didn't look at all comfortable. Also hauled my 6' 2" 180 lb. boss and he didn't fit well either. And he's in excellent physical condition. So, I'm left thinking that the GLK isn't the best choice for larger folks (not saying you are, though).

I've tried adjusting the lumbar support and the seat without any relief.

I think you're on to something 3.5L. My wife is 5'2" and doesn't have any problem being comfortable in the seat. I'm 6'2" 178 lb. and just can't find a comfortable position. I've been trying some homemade seat cushions that provide some relief. I found that too much cushion is bad, so I'm using some 1" batting/foam right now. I've ordered a Skwoosh gel cushion. Since it's gel, I got the 1/2" thick cushion. Hopefully it helps.

Try the tilt on the seat to give the back of your thighs more support and recline the seat a bit more.

That's how I have the seat adjusted now. It helps, but doesn't solve the problem.

On another note, after getting to drive a loaner 2012 GLK for 4 days, I'm really glad I went for a new '13 GLK. The '12 GLK was nice, but I reallly appriciate all the modifications they made for the '13, with the new engine leading the list.

I am very sensitive to seat comfort and it took me a while to find a comfortable position. I will recommend what I did and you can see if this helps. First, put the seat in the lowest possible position, lowering the front and rear to where the seat sits in its unlifted mode. Second, move the lumbar down to the bottom, or very close, then move it all the way in. Now, make the back part sit up relatively straight. It might take a little getting used to, but perhaps this might help.
