Abstract: Cushions for use in seating for boats and methods of using the same. According to one embodiment, the cushion is designed for use with a bucket-type boat seat and includes an insert and a casing. The insert has a J-shape and is made up of three foam pads joined to one another, with a first of the foam pads designed to be positioned over the boat seat, with a second of the foam pads designed to be positioned in front of the boat seat, and with a third of the foam pads designed to be positioned under the boat seat. The casing preferably conforms substantially to the shape of the insert and is designed to permit the insert to be inserted into and/or removed from the casing. The cushion additionally includes a fastener coupled to the casing for use in securing the casing to the boat seat.
