Experience Freedom of Movement
Yes, workers can crouch, squat, and bend the knees completely when using the Apex. It can provide support in the crouched position and assist when coming back up to standing. It is designed to offer as much freedom of movement as possible.
If workers find the support/assistance too extreme in some positions, the amount of support can be adjusted (or disabled entirely) using the on/off switch, easily accessible on the shoulder strap.
