Take a step up from the ROHO standard cushion and go with the Premium. The ROHO Premium Car Seat Cushion was created for the long haul traveler that spends hours in the saddle. Providing additional shock and vibration absorption, the Premium provides a more pain relieving ability and a more stable seating environment.
Because of its pressure distribution qualities, the ROHO Premium seating system has been very effective in reducing discomfort from sciatic nerve problems, hemorrhoids, and other medical conditions.
Only the ROHO Premium model features the unique and patent pending ISOFLO Memory Control. This control enables the driver to make quick adjustments to allow specific sections of the cushion to have more of less air in the cells than in others. Having problems with numbness in your legs? Use the ISOFLO control to easily lock air out of the front rows of the cushion, relieving the pressure on the back of the legs and promoting blood flow.
The ROHO Premium Car Seat Cushion inflates by mouth or with a small portable hand air pump that comes with the cushion. The key is proper inflation which means very little air. The goal is to sink or immerse yourself into the cushion to allow the cushions air cells to even out across your seating surface. Detailed instructions, with pictures, are included.
