Gravipod 18" Patio Umbrella Base Weight Bag - Adds Support for Offset and Patio Umbrellas - Fits Most Cantilever Stands, Up to 110 lbs Fill Sand Bag - Easy Setup and Durable

I purchased two of these for my patio umbrellas. They are very nice and made of durable materials. There is a Velcro opening from side to side that allows you to fill with sand. I used stone dust and it seems to be sufficient to be able to hold the umbrella down in the wind. Would definitely buy again, and recommend to othersUPDATE: just had a powerful thunderstorm roll through and the umbrellas were open with inset netting attached, while the wind wiped them, the umbrellas did NOT blow over - nice!

Good product to hold down our patio umbrell

I think these are a bit pricey but having said that they’re made well and solve the problem of falling umbrellas around the pool. Very good product.

A number of reviews mentioned that it was difficult to fill with sand and I thought it was pretty easy. Good weight and holds the umbrella securely.

I purchased my first Gravipod about a year ago. It worked so good I've purchase four more for all of my umbrellas around our pool. I originally put sand bags on the stands to try and hold them upright. but eventually a wind would come from a different direction and down they would go. These look great and work very well because the sand is perfectly balanced all the way around the stand. They are a bit difficult to move around once all the sand is added but not impossible. I recommend filling them up with as much sand as you can fit inside them (half way doesn't work on a gusty day). I highly recommend this product!

We have two cantilever umbrellas in our yard. We purchased that 4 piece set of triangular bases that fit in the cross base of the umbrella. Unfortunately when the wind blows the umbrella rocks enough for them to slip a little and we recently had one umbrella fall over. So I bought this Gravipod to sit on top of the other base pieces to add additional weight and support.The fabric appears to be of study construction. I've only had it a week so I can't speak to longevity yet. The top opens, maybe 6" wide, by a velcro strip. I found this very difficult to load with sand. Holding a sand bag and trying to pour while also trying to hold open the opening in the Gravipod was a challenge. Sand caked in to the Velcro and I had to keep scraping it out. TIP: Use very dry sand and a funnel to load. It's still a challenge to get the sand spread around inside the pod. I would also suggest this is a two person job to make it easier and less messy.Once I got the Gravipod 95% filled it was time to pick it up and lift into position over the pole. This was another poorly thought out approach on my part. The pod is obviously heavy and it's flexible so it's hard to lift into position. Kind of like a 3 yr old that doesn't want to get picked up and plays dead. And the hole in the center closes up because that's how fabric works. It was a two man job to lift it over the pole with my hand through the center of the pod to guide it without tearing the fabric. TIP 2: Place the pod on the umbrella base first before filling. I don't recall if there were instructions that mentioned this trick. I didn't look because this was so simple I was confident I could "figure this out myself".Overall I like the fact that is sits centered on the pole and can't slip off. I considered buying a second one for our other cantilever umbrella, but word of caution. Our 2nd umbrella swivels via a pedal on the base. This Gravipod would cover the pedal making it too difficult to use. Just something to consider before purchasing.

I purchased two of these for added stability on two 16 inch umbrella stands. These umbrellas are on our dock, and even when the umbrellas are closed, the wind tends to knock the umbrellas and stands over. These base weight bags were very easy to fill (50 pound bag of sand in each unit). The Velcro stayed open as I filled the bags and then closed up nicely. The material seems very durable. So far I have a very good impression of these. Two take-aways; not sure if I can leave these out on the dock during the cold winter months...the instructions didn't address this point. I'll most likely move these to an unheated porch, where they won't be exposed to rain, snow, and sun, however they will be exposed to the cold temperatures. Also...the filled bags would be easier to move, if a handle had been sewn into the bag (possible there is a handle and I just haven't noticed it).

Super easy to use, I purchased a 70lb bag of sand from Lowe’s for $6, it took two of us to work the sand into the weight, but it worked perfectly! Prior to my purchase, my umbrella fell over with even a small gust of wind (pictured). The base/umbrella was purchased at Home Goods and even though it’s cute, it was not designed to stand on its own!

Has been great at holding our very large umbrella in place. We are a lot mor confident in light breezes that the umbrella will stay put. Very well made.

This has made all the difference to the security of my parasol which is 3.3m in diameter. My patio is slightly raised so I get quite a lot of breeze - but it has remained stable.I filled mine with pea gravel which is easy to do using a plastic jug.I have left it out in really heavy rain and it is completely waterproof.

Great for keeping the garden umbrella in place! Good value and looks good just fill with sand.

Needs quite a lot of sand ,but works

It's as it was described.
