A powerboat seat comprises a removable seat cushion supported on a seat frame. A shock-absorbing device is interposed between the seat frame and the seat cushion such that the shock-absorbing device is supported on the seat frame and the seat cushion is supported on the shock-absorbing device. The shock-absorbing device comprises an upper panel having an external face that engages the seat cushion, a lower panel having an external face that engages the seat frame, a plurality of compression springs constrained between the upper and lower panels and straps connecting the upper and lower panels to constrain the compression springs between them whilst allowing limited relative vertical movement of the upper and lower panels at the front and the back of the panels. At least some of the compression springs are located towards the front and the back of the panels.
