The Ster 4MA also known as the Aries is a public transit passenger seat. It is marketed by 4ONE (formerly USSC) as the Aries 4MA in North America.

The seat frame and backing is of stainless steel or powder coated powder steel, and the seat inserts may be of a padded upholstered inserts or upholstered fibreglass inserts. For double seats, two widths are available: 35 or 37 inches. The inserts are interchangable between the two widths as the spacing between the seats is what is widened. The grabrails may be of stainless steel or injection molded plastic. A headrest option, which goes in place of the grab rail, and a tubular armrest option are available.
