Seat cushion fix

The drivers seat in my 2005 is getting uncomfortable after a while driving. Is a good remedy to replace cushions or maybe remove upholstery and add some?

 

I have a 1st gen and I had a professional upholstery shop remove the cover and add foam. Much better and done correctly.

 

Thanks. I'm leaning that direction too. I think its a matter of lumbar support. It feels best with the lumbar adjuster all the way out. But it's still not enough.

 

Anyone else experience degradation of the seat comfort? There's 150k miles, mostly from me. I'm 170 lbs. So I guess it's to be expected at some level. I just wonder how common it is.
So I was also considering finding a used seat assembly thats newer. Should be easy enough since they fit many years.

 

i think the left side of the seat pan foam gets mashed down alot from sliding in and out.
