A chair sled attachment assembly includes a base structure and a chair sled receiver supported on the base structure. The base structure is connected to a gaming machine cabinet in a base position projecting in a front direction from a front side of the cabinet and a base cover of the base structure defines a base volume separate from a secure volume of the cabinet. The chair sled receiver includes a chair sled receiving feature adapted for receiving a portion of a chair sled assembly when a chair sled is placed in an operating position on the gaming machine. A removable cover portion of the base structure is removably secured to the base structure in a cover position covering the chair sled receiving feature.
