Pressure sores on the heel and elbow are a real concern for anyone with limited mobility, and prevention is far better than treatment. These Gelbodies protectors use a medical-grade pressure-relieving gel — the same type used in high-end wheelchair cushions — to cushion those vulnerable points and spread weight more evenly. Better pressure distribution means better circulation, which is what keeps tissue healthy. Comfortable enough for extended wear, though it’s recommended to remove them after 12 hours. Supplied in pairs.
