Trillium 1300 professional custom made seat (sofa style) made to fit the front contours. In the corners the foam had to be built up to over a foot thick to achieve the desired look. Easily fits all 1300 Trillium trailers. Standard size 77” long and 26” deep. Zippered covers for easy cleaning. We are going in a different direction and plan on having a dinette made in its place.
