See a lot of likes? Mom is coming out of rehab next Thursday and I bought a ROHO softflex cushion as I have heard great reviews. Question is, do you still have to turn the patient every 2 hours or can the patient sleep uninterrupted for 4-5 hours? I have been told they can. They also get out of bed and sit in a chair and on the sofa during the day. Any additional feedback would be helpful.
