No, it's not recommended to use the X Pole A Frame on uneven ground. The A Frame is designed to be set up on a flat and stable surface, and using it on uneven ground can compromise its stability and safety. Uneven ground can cause the A Frame to wobble, tilt, or even tip over during use, which can be dangerous for the user. It can also cause unnecessary wear and tear on the A Frame, potentially leading to damage or malfunction. If you need to use the A Frame outdoors, it's best to find a location with a flat and stable surface, such as a level concrete pad or a stable grassy area. You can also use a thick yoga mat or a rubber mat to help stabilize the A Frame on uneven surfaces, but this is not a recommended solution as it still may not provide enough stability and can still compromise safety.
