A storage system, having in combination one singular shelf or multiple shelves infinitely adjustable on an upright member. The upright member is a singular support structure with at least three parallel grooves running longitudinally below a front face of the vertical support, the grooves having a continuous sectional profile and each groove opening in the front face through a channel. The shelf or shelves (6) are formed on a back side with at least three tongues (7), the tongues being integrally formed in the shelf and adjoining the back side through a neck portion (8). The tongues are insertable in the grooves while the neck portions occupy the channels. The neck portions are curved so that the tongues project upwards from the shelf upper surface at a slanting angle, such that the tongues are frictionally arrested in the grooves when the shelf is pivoted to bring the tongues to a tilted position in the grooves. In the arrested position, the back side (10) of the shelf has a load bearing contact against the front of the vertical support.
