I have a 2005 LS430 and would like to replace the front seat foam. It seems that the support is just not there. Has anyone done this? I can purchase the seat foam from my Lexus dealer and have it installed by another interior company.

Will this give me the new car support? Will this cause any problems?

Looking for more comfort on my drives.

My father and I took the seat bottom out of his 2005 and in the middle section cut out some of the old foam and installed some memory foam. Worked out pretty well!

 

You can buy the seat cushion from lexus and have a upholstery shop install it. If you have an upholsterer rebuild the seat possibly the cooling feature on the seats will be weak, or weaker than it already is.
