An object storage assembly includes a pair of storage units. Each of the storage units may be positioned beneath a dashboard of a vehicle on a passenger side of the vehicle. Each of the storage units has a rear wall and a front side. The rear wall corresponding to each of the storage units is curved. Thus, the rear wall corresponding to each of the storage units may follow a contour of a floorboard of the vehicle beneath the dashboard. A passenger may sit in the passenger side of the vehicle when the storage units are positioned beneath the dashboard. The front side corresponding to each of the storage units is open to store objects.
