Yes!  Since the seat is attached with Velcro and can be easily removed, you can replace it with a seat that is more to your liking. While we do not sell any other variety than replacements of the original cushions, there are third party companies that manufacture custom made seats.  As long as the seat you purchase conforms to the existing size (length, width, and height) of the seating area, you may be able to replace the existing one with one that is more suited for your needs.As the third party seat cushion is not too thick, it will not impact the fold-ability of the chair.  If you do choose to put an additional cushion on the chair, or use a thicker seat, you may need to remove it for folding.
