2006 Electric Driver's Bucket Seat Upgrade?

Hi, I have a 2006 Tundra Access Cab that I bought from my son who bought it brand new in 2006. I love this truck! Only 120K miles on it...........literally looks like new.

I am physically disabled because of Spinal Stenosis, Scoliosis, two herniated, one ruptured disc. The standard mechanical seat is good for around town etc but when we go for 50 miles or more I have a lot of trouble getting comfortable.
I would like to switch the drivers mechanical bucket seat to a power adjustable seat. How hard would it be to do it? Do I need the whole adjustable seat? Just the seat pedestal to put my current seat on?
Thanks for your help

 

I would recommend swapping out the seat for one from an Escalade. @ethan1911 did that and looks extremely comfortable.
