This seat has enough flexibility to fit a Pro-form GL36. The seat on the GL 36 is extra wide (0ld school) I tried other covers, but they were too small. The gel pad doesnt exactly fit the width of the OEM seat, it is a little smaller, but the shroud will fit around the seat and you can cinch everything down. It elevates you a inch or so. It feels soft and comfortable. This was a good deal. Ive had to rejuvenate my old GL36. New motor $101. new pedals $26 (OEM straps were $45 each ?), new seat $2See full review
