Quick answer：

An open-air air cushion swimming pool is a pool with an air cushion base instead of a solid ground. It provides a soft, floating surface for swimming and is often used for recreational purposes. These pools can be found in parks, resorts, or as part of water parks. They are designed to be safe for users of all ages, including children and the elderly. The image would likely show a pool with a smooth, cushioned bottom and surrounding landscaping, possibly with people enjoying the water.
