Block seat (BlockSeat)
Also: BlockSeat
A block seat is a box-shaped inflatable seat. It adds height and wedges itself between the tubes.
The Anfibio blog describes a trick: an extra block seat in the middle of the boat acts like a stable ¾ floor mat. It stiffens the hull and adds buoyancy and stiffness in whitewater. On land it serves as a seat cushion. According to the configurator, the Anfibio BlockSeat weighs 300 g.
