Designed to be mounted on the backrest tube, the Arm Hook X3 caters to individuals with compromised trunk stability. By hooking the arm around the arm hook, activities such as adjusting the sitting position in the chair or holding on to pick things up from the floor are made easier. 

It's essential to note that the Arm Hook X3 is not intended for lifting the chair with the user and should be used strictly for its designed purposes.
