The seats on my 2005 HAH are just fine for an hour's drive, but for long trips, not so much. Ever since new, an all-day trip leaves the backside pretty sore. I've adjusted the seat seven ways from Sunday with no change. Likewise the (unadjustable) passenger seat gets pretty tiresome on a long drive. I love my HAH, but I can go all day with no discomfort in my 2000 Acura TL.

Has anyone modified, adjusted or replaced their front seats to improve comfort?

 

I haven't experienced any problems with seating comfort. I used to commute 4.5 hours each way, and didn't have any problems. I've driven this car for six years and +90,000 miles now. I'm sure it comes down to anatomy. Some seats are more comfortable than others for certain people. I drove a '02 TL for a while. Similar to the '00? I think the seat fit better (wrapped around you better, mostly felt during aggressive cornering), but I don't remember it being any more comfortable.

They're similar cars, so I wonder if you can just pick up some '05 or similar generation range TL seats and they'll fit right into your '05 HAH? Heck, my driver's seat has a small tear in the lower cushion. It costs more than $500 to buy a replacement cover from the dealer. It'll probably be cheaper for me to do the TL seats in my car, too.

 

One thing I did notice when test driving the '05 TL and '05 HAH is that the seats in the TL are perforated. Wish the HAH seats were perforated as well.

 

Checked a local salvage yard (why don't we call them junk yards anymore?!). No TL seats.

 

We find ours OK, firm base like old Benzes, tad wide for us but good design for large Americans BUT, I may buy an LS Lincoln or XJ8 for the a/c seats here in FL-much like heated seats for you in the other 49.

 

Hmm, other 49 states? I lived in AZ and NV, and would say those two states require cooler seats more than FL.
