I'm hoping someone here has the knowledge to share with me.

I have a 2018 Accord Touring 2.0T It is my first Honda ever (I'm 59 been driving since 16) and I LOVE it EXCEPT for the seats. My GAWD these are the most uncomfortable seats my *** has ever been on in my life.

Saying that, I hear the Acura RDX seats are extremely comfortable. Which brings me to my question. Will RDX seats fit without huge modifications and operate in an Accord?

 

I wouldn't bet on it. That said, for enough money they can most likely be made to fit and to operate correctly.

 

You would have to do your homework to see if it fits.

The first part is to see if the rdx seat will bolt to the floor of your accord.
Look at OEM part numbers for the base of the seat for your car and a donor rdx on OEM parts sites like hondapartsnow.com and acurapartswarehouse.com. You may be lucky and they have an identical base. Then you would be able to bolt the rdx seat to your accord floor. If not, then it may be challenging to bolt the seat to the floor.

The next item is to look at what electrical components you have on both seats and how to wire them up.

 

That would be my guess also ....
