The AngleChanger System is the proprietary patented technology and absolute reliability for the adjustment of the backrest. AngleChanger allows you to adjust the backrest in 6 positions. The movement system of the back of the beach chairs is one of the most stressed parts and therefore subject to breakage. In the panorama of Italian Style sun loungers, AngleChanger is the most reliable product being virtually indestructible, and more performant (offering 6 positions, from the completely flat to 0, up to the reading position at 60 degrees with steps of 12). Important features of the System are the fact of not sticking out with the tip to avoid accidental breakage, not to have the side "stops" of the end of the run also subject to breakage, not to have counterweight metals inside it that over time oxidize, to be installed with repositionable bolts for any replacement of damaged parts and to have all components ambidextrous to facilitate the unlikely replacement of a component. The Classic version is super-controlled and allows the lifting of the backrest by pulling it up to the preferred position, while to get out of position, you need to operate the lanyard, lower it at will and release the lanyard. From 2024 it will also be available in the wireless version: it is a new proprietary patented technology, an evolution of the Classic AngleChanger System in which the System loses the use of the cord necessary to make the descent of the backrest, which in this case occurs only after lifting the same over the most vertical position, up to about 65 seat; after that it will be sufficient to lower the backrest to the most horizontal position and then go up to the preferred position. It is therefore a semi-automatic Sequential movement system. An important feature of the Wireless AngleChanger System is the possibility to perform at any time and in a few seconds, the Downgrade to the Classic AngleChanger System, removing the Receiver and Tongue components and applying the Lanyard, as well as the Upgrade back to the Wireless AngleChanger, by reinserting them and removing the Lanyard. Thanks to this feature, we obtain the highest level of customer satisfaction as it maintains the full freedom of choice on how to operate the movement of the backrest that remains one of the most delicate parts in the use of the beach bed.
