Abstract: A tri-fold lid storage box which enables the user to convert available storage space underneath a bed into usable storage. The storage box is comprised of a separate box and lid, the box having a triple reinforced front panel for pulling the box outward, the lid having a specially designed lid which can fold back either 1/3, 2/3 or be completely removed. The lid is also removably attached to the storage box and is specially designed so the user may lock the lid into the 2/3 open position so that the user can view and manipulate the contents of the box without having to hold the lid open. The boxes are specially dimensioned so that they fully utilize the storage space available underneath a standard size bed.
