Whats the most comfortable?

“Seats” Leagcy . They are made in Reedsburg WI. Not cheap but probably the best out there ​

 

I prefer the bostrom wide ride xl w memory foam they are pricey 800-1000 but after a year I blew out a seat cushion air bag and w nothing but the seat serial number I got a brand new seat bottom for free! no hassles no fuss and as far as comfort... the back cycler is the bomb I drive / sit 14 hrs a day and weigh 300lbs seat is awesome I have tried almost everything on the market except the bose$$$$

 

I will agree with you on those KW seats, I hated mine, they were terrible, and that was in a new W900. I would look at Seats like was mentioned above. You may need a seat adapter for the floor if you go with them. Their bases tend to be a bit smaller vs the National seats. I like Seats as the actual seat is a tad bit shorter than the National seats.

I also like some of the Bostrom line too. One of the best seats I ever had, that was in a 2004 Pete, fit my tail end and lower back like a glove. Very comfortable, but I don't think they make that particular line anymore.

 

Most likely your seat cushion foam is worn out, compacted and flat which makes the seat uncomfortable.

If you want don't want to spend thousands on a new seat, and the original seat cover is still good, you can order new seat foam and recover it with your original seat cover and save some money.

 

National Seats are comfortable. Had stock freightliner seat tossed for one of these. Not pricey, i think maybe $700 with two armrests.

 

Broomstick.....Thats Funny!
I have the same issue with the same truck but its a 99!
I remember a thread about this subject a few years ago, the best was a Bose, but its over 4K.
Knoedler seems to be a good seat which starts out just under 1K but with all the options could get in the mid 2K, i am leaning towards the Knoedler Low Rider without the heat, cool and vibrator.

 

I had knoedler low ride in my last truck.

Best seat I've ever had

 

I'm personally fond of National I've had my current one for 4 years and it's still comfortable. It cost me around 700 iirc

It's my second new one (in different trucks) when I buy another seat it will be a National

 

Swap the seat bottoms with the Pass side. Does not take but a minute or so and you can swap them. That will be fast and may well get you through until you can get a new seat.
The T600 I have, some one put the same seats in it. That is in my 2005 Chevy Kodiak C5500. There high dollar seats, and I did not think I would like them. But man there like sitting at home in my Lazyboy.
