This is the only smart bed that helps alleviate back pain and other aches by monitoring your sleeping position and automatically responding with your desired amount of support. Paired with an app available for smartphone or tablet, the unique bed monitors nearly 2,000 pressure points across the body and adjusts overnight to provide each sleeper?s preferred level of firmness in five zones under the head, shoulders, lumbar, hips, and legs. Three operating modes lock in these settings in advance or continuously adjust depending on your position. All mechanical components are imperceptible beneath layers of dense memory foam, and the medical-grade, leak-resistant air chambers inflate and deflate quietly to not interrupt shuteye. Cover removes for laundering.
