Equipped with a head fixation device, it delivers full spinal stretching during use to ease compression. The wheeled design allows easy movement before and after use without heavy lifting. Adjust the device to a comfortable length according to your height first, then lie flat for use. Secure your ankles, place the two soft foam rollers under your armpits, fasten your head with the head strap and hook-and-loop fastener, then operate the stretching function with your right hand.
