If you are like most people the backrest is an absolute must. It is the difference between relaxing and tension, between an enjoyable kayaking experience and enduring the day. The backrest are phenomenal area there adjustable with the straps in the attached directly to the kayak held on by metal loops attached to the kayak with metal rivets or screws. Having a backrest that is comfortable like this one allows you to enjoy hours on the lake. Of course, if you are like me you will still need to stand up from time to time and stretch the limbs and get the blood flowing to enjoy more time on the water. The backrest is especially helpful if you are fishing. You obviously use a lot of your arms and shoulders when casting and reeling in and leaning back slightly the backrest can handle all of that just fine. The backrest is not cheaply made. Fortunately, it is included in the purchase. It is made of high-quality material and helps provide an enjoyable kayaking experience maintaining decent posture and back support. In addition to the backrest there is a padded seat-they go hand-in-hand. You aren't sitting simply on a plastic surface. Our goal is to provide the best kayaking experience.
