The most common seat found on scooters is a chair-style seat similar to those found on boats. The basic seat is molded hard plastic or fiberglass, but most manufacturers offer a padded-seat option, usually with a choice of vinyl or fabric upholstery. Vinyl upholstery is frequently less expensive, but because it is a slipperier surface, it may not be the best choice for those whose disability makes it difficult to maintain position or balance.
