This is really a serious boat chair. It has a metal folding/hinge mechanism with heavy foam rubber cushioning, enabling you to sit in it comfortably – without fatigue – for long periods. It has a securing strap to hold rear seat down. It comes with a set of 4 stainless steel metal thread mounting screws with threaded inserts. It features a high back for further comfort. You could fit a pedestal or combination swivel to this easily
