Abstract
A climbing apparatus that rests on a surface includes a flip ladder that can move between a straight configuration and a stepladder configuration. The apparatus includes a tray having a plane attached to the flip ladder that moves with the flip ladder between the straight configuration where the tray plane is essentially parallel with the ladder in a stowed position and a stepladder configuration where the tray plane is essentially parallel with the surface in an open position. A method for climbing includes the steps of moving a flip ladder between a straight configuration and a stepladder configuration. There is the step of moving a tray having a plane attached to the flip ladder from a stowed position where the tray plane is essentially parallel with the ladder to an opened position where the tray plane is essentially parallel with the surface. There is the step of moving the flip ladder from the stepladder configuration to the straight configuration which causes the tray to move automatically into the stowed position.
