Mine is held in not just by the velcro, but also by the hip braces which are over the seat bottom. I has held up well. The velcro just keeps it from sliding around. If I remember right, the creature comfort seat came with a special glue for the velcro, and it has not come up. The hooks are glued to the hull, and the loops are sewed into the seat cover.

: I tried the velcro route and ended up gluing my seats in. A couple of times
: getting wet and the velcro let go. It wasn't the glue to the seat or the
: boat but the glue backing to the velcro cloth that let go. I tried contact
: cement on the velcro but it eventually let go as well. All I can think of
: is to glue the seat to something thats held in mechanically or epoxied in.
: But then that will bring the center of gravity up. I guess I'll just leave
: well enough alone for now.
