Stable and Easy-to-Use Umbrella Stand
Size: 1-Piece, Color: Black
💧 Water-Filled Design
The ability to fill it with water makes it lightweight to move around when empty but very stable and heavy once filled. It holds the umbrella securely without tipping, even on windy days.
⚙️ Build & Compatibility
The stand feels sturdy, made from durable plastic, and the black color is neutral and fits well with most outdoor decor. It fits standard umbrella poles nicely, and the tightening mechanism is easy to use and keeps the pole firmly in place.
🚚 Portability & Setup
It was easy to set up — just fill with water (or sand if you want extra weight) and insert the umbrella. I like that it’s less heavy than concrete bases but still very effective.
✅ Pros:
Lightweight when empty, easy to move
Very stable when filled with water
Simple to use and adjust
Durable plastic design
Fits most standard umbrella poles
❌ Cons:
Needs regular refilling if you use water (can leak slowly)
Plastic may show scratches over time

Avoid at all costs. Rusty and not stable. Confusing customer service.
Size: 1-Piece, Color: Black, Size: 1-Piece, Color: Black
Do not buy!!! Cheap product and bad customer service! The product is rusted upon delivery. It is not stable and will not hold an umbrella rated for 22lb stand upright with water alone. They wanted me to refill the stand and send them pictures of the tilt even though the rust should warrant a full refund with shipping covered, if they were a good company. The company is giving me the run around on a return and conflicting information. They said they I would have to pay for the return, then that they would, then and try keep trying to offer me a discounted rate and charging me shipping. Here is a copy of the communication. They offered $10 telling me that rust is not covered in their warranty, even if it arrived rusty!
First message: "After the returned item is delivered to our warehouse with no issue, we will return your amount."
Second message: "Generally, rust can be caused by many factors and is not typically covered under our warranty. However, as a valued customer, we’d like to offer you a USD 10 price return if you choose to keep and continue using the base as it is.
Please let us know if this solution works for you, and we will process it right away."
