Trymaker Kayak Seats with Back Support is a thick, adjustable replacement seat that adds lumbar support, comfort, and onboard storage for kayaks, SUPs, and inflatable boats.
Whether you paddle for hours or enjoy casual outings, this upgraded seat combines a plush 1.97-inch (5 cm) cushion with a high, ergonomically shaped backrest to reduce fatigue and stabilize your position on the water. Built with reinforced straps, zinc-alloy buckles, and a waterproof storage pouch, it’s designed to fit most sit-on-top kayaks, inflatable kayaks, SUPs, tandem boats and other small craft.
Yes—the seat base includes Hook and Loop tape and heavy-duty adjustable straps so it remains secured to most kayak surfaces and doesn’t slide during strokes. The reinforced stitching and metal buckles give extra reliability when you lean, twist, or brace.
The seat uses a layered cushion for padding plus a 3mm high-hardness PE board inside the backrest to hold an ergonomic shape. That combination supports the lumbar curve and spreads pressure, helping to limit lower-back strain during extended paddling sessions.
Materials were chosen for marine use: corrosion-resistant zinc-alloy buckles, robust stitching, and a waterproof PVC storage bag keep the seat functional season after season. The straps and hardware resist salt and freshwater exposure when rinsed and dried after use.
The Trymaker replacement seat uses a universal mounting and sizing approach to work with most inflatable kayaks, sit-on-top kayaks, SUPs, and tandem kayaks. Its adjustable straps and flexible base let you adapt the fit to different cockpit shapes and deck layouts.
Who is this for? Paddlers who want more comfort and support on every outing—recreational kayakers, SUP enthusiasts, weekend anglers, and anyone who spends long stretches seated on small watercraft. If you frequently feel lower-back discomfort, need a stable seating position, or want onboard storage for essentials, the Trymaker seat upgrades basic factory seating into a more comfortable, durable setup for day trips and extended paddling.
Q: Will this seat fit my inflatable kayak or SUP?
A: Yes—the universal design and adjustable straps fit most inflatable kayaks, sit-on-top kayaks, SUPs, and tandem kayaks.
Q: How much padding does the seat provide?
A: The cushion is approximately 1.97 inches (5 cm) thick with a three-layer build for added comfort and shock absorption.
