This seat cover is a direct replacement for the original upholstery fitted to Grammer MSG97AL, MSG 90EL, and MSG 97EL suspension seats, including Dual Motion and swivel-base variants. It encloses the foam cushion and backrest, protecting them from dirt, moisture, and wear during daily operation. The cover is cut and sewn to match the original contours, so it fits the seat frame without sagging or bunching. A torn or worn cover exposes the foam to accelerated degradation, which can lead to discomfort and reduced operator support. Because this is an original-manufacturer part, the stitching pattern and material grain match the factory assembly, preserving the seat's intended appearance and fit.
