I didn't know Millenium sold "boat" seats until I read this thread. Their treestand seats are supposed to be very comfortable so I'm sure the boat seats are the same. I have to replace the fishing seats in my boat and I'm going to give these a hard look.

Both seats are rated at 400 lbs so why is the saltwater seat considered heavier built? Just uses larger tubing?

Also I can't find anything that says the B100 has UV resistant material but the SW100 says it's made with UV resistant material. Does the B100 have the UV protected material on it? If not I'll go with the SW model just because of that.
