A seating support device for use in conjunction with a seat to support a user during travel. The support comprises a main body of flexible material that is capable of being manipulated to alter a three dimensional form of the body into one of multiple usable forms. At least one of the multiple forms is a support form having a recess for a user to rest their leg and/or foot therein. Other forms include a second support form and/or a pouch or carry bag form. An attachment mechanism associated with the body is provided for attaching the body to a support structure separate from a seating surface of the seat in the at least one support form. The body is also configured to couple the seat in use.
