The best bed height for you can depend on your age. Many older people with moving difficulties find it easier to get out of a higher bed. If you need to raise a low frame, such as a platform bed, try a set of bed risers. Try to sit on the edge of your bed, with your feet flat on the floor. If your knees are perpendicular to your body instead of raised or lowered, then your bed is probably at a good height for you.
