finally managed to remember to measure last night passenger seat sitting surface: 21" wide, 18" deep base: 22" wide, 21" deep seat back: 22" wide, 5-1/4" high on port, 6-3/4" high on starboard (follows curve of deck). driver seat: 23" wide at widest point base: 13" wide, 21-1/2" deep, with 1-1/2" lip sticking down in front. If you need anything more speciffic, let me know.
