How to Reupholster Back-to-Back Boat Lounge Seats

Item # X-HT-300103

On-board our Powerboat Makeover, a 1982 Regal 245 XL Ambassador, all of the original upholstery had seen better days, so we reupholstered all of the seating on the bridge deck. That included a back-to-back lounge seat, which also functions as the helm seat. In this video we’ll show you step-by-step how to reupholster a back-to-back lounge seat.

Before and After Back-to-Back Lounge Seat Upholstery

A back-to-back lounge seat is comprised of two chairs with adjoining backrests. All of the pieces of the chairs are on hinges, so the seats and backrests can be laid flat to create one, long lounger. There are several different styles of seats like this, so yours might not be quite the same as ours. We recommend paying close attention to how your chairs come apart, maybe even take photos of the disassembly process, so you can put it back in reverse order. It’s also a good idea to remove the old fabric carefully so it can be used to pattern your new fabric pieces.

We kept the upholstery in the same color scheme as the other seats on this boat, using three colors of Morbern® Seabrook Vinyl; a Lite Glacier channeling fabric, and Stinger Bisque and Midnight vinyl. To keep the look consistent we reused the pattern we made for the lounge cushion (200704XHT) so we could replicate the same curved design.

We don’t cover the disassembly or reassembly process of the seats in the video, because this is specific to each seat design, but we do include how to upholster the base the seat sits on. We’ll also show you in detail how to pattern your fabric using the old fabric, how to cut the foam and how to upholster the seats.
