A positionable platform for an interior of a vehicle comprising: a planar top surface; a bottom housing with a channel; and a releasable locking mechanism disposed between the planar top surface and the bottom housing. The releasable locking mechanism includes: a first bracket; a second bracket layered beside the first bracket; a button accessible for manipulation connected to the first bracket; a locked state where the second bracket extends into the channel; and an unlocked state where the movement of the button in a first direction causes movement of the first bracket in the first direction, which causes movement of the second bracket in a second direction different than the first direction that withdraws the second bracket from the channel or reduces the extension of the second bracket into the channel.
