Modular furniture equipment structured to form a mobile computer workstation for users; the modular furniture equipment comprising: - a box frame approximately parallelepiped-shaped, the box frame having a longitudinal reference axis and being provided with a side peripheral rim, a larger front wall and a larger rear wall, which internally delimit, together with said side peripheral rim, an internal containment compartment; - a user interface panel coupled at the top to the larger front wall of said box frame; and - a folding seat connected to said box frame so as to rotate about a first rotation axis approximately orthogonal to said reference axis, between a rest position, wherein said seat is arranged inside said compartment so as to be hidden inside the frame, and a work position, wherein said seat is arranged outside said compartment to allow the user to sit down; - a rest plate pivoted on said frame above said seat to rotate about a second rotation axis parallel to said first rotation axis between an extracted position, wherein the rest plate is approximately orthogonal to said reference axis, and a retracted position, wherein the rest plate is arranged inside said compartment in a position approximately parallel to said reference axis; said modular equipment being characterized in that it comprises: - a backrest, which is pivoted on said seat to rotate about a third rotation axis parallel to the first rotation axis between a reclined position, wherein said backrest is folded resting on the seat when the seat is in the rest position, and a raised position, wherein the backrest is approximately orthogonal to the seat when the seat is in the work position; and wherein, when the rest plate is in the retracted position and the seat is in the rest position, the rest plate abuts against the backrest in the relative reclined position. - a box frame approximately parallelepiped-shaped, the box frame having a longitudinal reference axis and being provided with a side peripheral rim, a larger front wall and a larger rear wall, which internally delimit, together with said side peripheral rim, an internal containment compartment; - a user interface panel coupled at the top to the larger front wall of said box frame; and - a folding seat connected to said box frame so as to rotate about a first rotation axis approximately orthogonal to said reference axis, between a rest position, wherein said seat is arranged inside said compartment so as to be hidden inside the frame, and a work position, wherein said seat is arranged outside said compartment to allow the user to sit down; - a rest plate pivoted on said frame above said seat to rotate about a second rotation axis parallel to said first rotation axis between an extracted position, wherein the rest plate is approximately orthogonal to said reference axis, and a retracted position, wherein the rest plate is arranged inside said compartment in a position approximately parallel to said reference axis; said modular equipment being characterized in that it comprises: - a backrest, which is pivoted on said seat to rotate about a third rotation axis parallel to the first rotation axis between a reclined position, wherein said backrest is folded resting on the seat when the seat is in the rest position, and a raised position, wherein the backrest is approximately orthogonal to the seat when the seat is in the work position; and wherein, when the rest plate is in the retracted position and the seat is in the rest position, the rest plate abuts against the backrest in the relative reclined position. - a backrest, which is pivoted on said seat to rotate about a third rotation axis parallel to the first rotation axis between a reclined position, wherein said backrest is folded resting on the seat when the seat is in the rest position, and a raised position, wherein the backrest is approximately orthogonal to the seat when the seat is in the work position; and wherein, when the rest plate is in the retracted position and the seat is in the rest position, the rest plate abuts against the backrest in the relative reclined position.
