In the Summer, it's very comfortable to organize activities or lie down outdoor. But the premise is that you need a piece of shade to protect your skin from the Sun. At this time, a 3-tier patio umbrella can provide you with such a large shade to enjoy the beautiful Summer. This patio umbrella adopts crank lift design, which can be easily opened and closed, so that you can use it at any time when the Sun is shining brightly. In addition, it also adopts button tilt technology, which makes tilting the patio umbrella effortless and provides maximum shade. Therefore, it is suitable for both shading and rain protection (the base is not included). Simple assembly without tools provides more convenience for you. Installation instructions and installation videos are available for reference. Please close or remove the patio umbrella during windy or inclement weather to avoid falling over (the base is not included). If you encounter problems during the assembly process, please contact us directly and we will reply you as soon as possible within working days.
