This recliner is equipped with thoughtful side control buttons and a practical built-in USB port. The operation is extremely easy. Just press the side control button and you can easily switch between lying down or sitting down. Moreover, the button has a good cushioning effect when triggering the action, which can cleverly prevent you from standing up too suddenly or falling accidentally due to sudden movements, thus ensuring your safety in use. In addition, the chair's built-in USB port is a highlight. When your mobile phone or other electronic devices are running low on power, you no longer have to worry about looking for a power socket. You can charge them directly here, which is convenient and quick.
