An improved sled provides a support member having an ice block removably coupled to its underside. The ice block is coupled to the support member by an adjustable retention means. A pair of support blocks are connected to the underside of the support member and have threaded holes disposed therethrough. Locking screws are placed through each of the holes, and are coupled to compression blocks. As the locking screws are turned, the compression blocks move inwardly, thereby gripping the ice block. As the ice melts, the locking screws can be tightened, so as to maintain a firm grip on the ice. In the preferred embodiment, the support member is formed in the shape of a seat.
