Case 730,830,930,1030 Comfort King Seat. New USA Made Replacement. This is an IH Seat design with a Comfort King Adaptor Plate included to attach to the Comfort King Suspension. All steel construction. A very Solid & Quality Seat. Real comfortable with a full 4″ Thick Foam Seat and a full 2″ Thick Foam Back and Armrest. The Arm Rests are supported at the sides to make them solid, & are adjustable up or down & forward & back. The Upper Back Rest is also adjustable up or down. These features are really 1 up on the CASE. Lets keep that to ourselves. We have 1 of these seats on our 730CK and are really pleased with it. I have seen cheaper replacements, and can sell them, but I don’t like them. They are Wood backed & flimsy. Compare this seat with what you are sitting on now. Come-on, the ol’e girl deserves it, & so do you.
