New Member - and new 2025 AT4...
I've been working the seat issue for 2 weeks, and would love more detail on Master Chief BT's setup especially the foam work. Love the color combo he chose!
Here's what I've found...Regarding the Seat Bottom Only (Ventilated/Heated)
1. GM uses same seat bottom Foam Cushion, Spring, Frame in every 1500/2500 series truck they make in 2024-2025.
2. Leather in the Denali Ultimate is a different quality and softness.
3. 30 min drive in Ultimate = no pain vs. 30 min drive in AT4 = Pain
4. The quality, design, and softness of the Denali Ultimate is the only difference in the seats.
5. The foam could definitely be improved but simply changing the seat cover from the AT4 to a Denali Ultimate makes a world of difference. I think the Denali Ultimate cover is not as tight and therefore allows the cushion to expand and not be as firm.
@Master Chief BT would you mind messaging me the contact information for the shop in Tyler Tx that did your work. Love to replicate exactly what you / they did.
