The Rubix kayak seat is made from high quality corrosion resistant materials for your supreme comfort. It features a detachable bum pad - great for a bit of lift (takes the pressure off your hamstrings), but you can take it out if you want more stability. The back is nice and high with 2 adjustable straps on each side so you get the perfect angle of support. The clips are brass to prevent corrosion. There are additional rear straps to keep the seat upright when you are getting in and out.
