A pair of arm supports that clamp onto the plastic tray and give the child somewhere to rest their forearms while they are standing. They mount left and right on sliding brackets, so you can set the spacing to suit the child.
Supported arms make a real difference to how long a child tolerates being upright. With the weight of the arms taken, the shoulders settle, the head follows, and the child has a stable base to reach and play from without bracing on the tray edge.
They are worth considering for any client whose arms drift or drop during standing, or who fatigues quickly through the upper body.
