I had a small issue with my Seth Laam seat that I could live with. I called him up to let him know what had happened so he could avoid it in the future.
He called back and said he would send a prepaid label to send the seat back to him. He fixed the issue and added some more padding to the passenger portion. Then shipped it back to me at no charge.
I was very happy. Pricing | Laam Custom Motorcycle Seats
Seth does good work. He learned his craft working for Mayer saddles. His communication was not great at first when he started his company but may be better now, I heard he hired someone to help with admin issues. He has done a couple saddles for me and I was pleased with his work.
With that said if I wanted a custom seat the only choice would be a Russell. Seat comfort is a very subjective issue but I cannot recall an unhappy Russell customer. I cannot say the same for ANY other seat company.
