Rafio is a rare ultra-low bed (as low as 15cm) that considers users with swallowing difficulties. Its backboard, split into upper and lower sections, not only broadens the bedridden user's view but importantly aids in achieving an ideal eating posture (reducing the angle between the larynx and esophagus), reducing the risk of food entering the windpipe and mitigating choking hazards in the elderly. This is a distinguishing feature from other electric beds. The upper backboard effectively bears the user's upper back weight, relieving pressure on the buttocks, especially the sciatic nerve area, and decreasing abdominal shear force, significantly reducing the risk of pressure sores from prolonged bed rest. Rafio can be adjusted according to different users' height and body shape, preventing slippage and friction from long-term use, thus avoiding additional physical issues. Therefore, Rafio is not only suitable for general elderly users, but it's specifically designed for those with severe diseases, such as stroke, advanced Parkinson's Disease, and severe Alzheimer's Disease, which can lead to swallowing difficulties.This bedframe can be adjusted to fit different body shapes and heights, preventing discomfort from prolonged use. Rafio is particularly beneficial for individuals with severe conditions like advanced stroke, Parkinson's Disease, or Alzheimer's Disease, who may face swallowing difficulties.
