driver seat springs weak...?

Hi, this is Bo, an auto expert on RepairPal's Car Genius team! It sounds like the seat cushioning or support springs in your 2019 Toyota Avalon’s driver seat might be wearing out early, which could be a defect or just a comfort issue. A common fix is to have a shop reinforce the cushion or springs, or replace the foam padding with something more supportive. This could be done by an upholsterer or a dealership, depending on whether you’re looking for original parts or simply a firmer feel. Toyota seats are usually known for durability, so if they are under warranty, check with the dealer to see if they'll replace or repair them.
