14-Inch Round

This is my third Gravipod order. I live in the desert, and the monsoons can be very destructive to patio umbrellas. Although my umbrella bases should be able to withstand the winds, they don’t. I ordered these bases as extra support, and they work extremely well. They have not faded from the sun, which is an added bonus. I highly recommend these for ease of use, cost, durability, and overall aesthetics.

Used this to weigh down a patio umbrella on my deck, and it works perfectly. Super easy to fill with sand (I used play sand from the hardware store), and once it's full, it stays put. The material feels tough and durable, and the design makes it easy to center around the umbrella pole. We've had some breezy days, and the umbrella hasn’t budged. Great solution if you don’t want a heavy, bulky base taking up space. Definitely recommend!

The sand bag is a much more affordable alternative to the hard plastic weights. Look. Its awesome for an uneven grass area where the hard plastic weights wouldnt lie flat. There are some things I wish I'd have known going in. Hopefully this helps you... ...I would DEFINITELY recommend some sort of larger funnel to fill this. Even an open ended Pringles can would help. The opening to fill the bag isn't as tiny as other reviews made me believe it was, but it could be much larger than it is. It is closed securely with some strong velcro. However the velcro makes it ANNOYING to fill. USE DRY SAND!!! OMG USE DRY SAND Wet sand doesn't flow. (what a great tattoo idea) Wet sand just clumps on the velcro. Wiping it away just spreads it into the the velcro. I always hose it off with a low pressure setting. You have to or the velcro won't stick. So be ready for that fun part. Maybe have a cooler of your favorite alcoholic beverage nearby. Because it's not a quick chore, and if you're me, you'll choose the hottest afternoon so far this year to do this little project and just want to chuck the whole umbrella, sand bags and all across the yard after you've delicately loaded several dozen handfuls of sand into the bag because you don't want to manufacture an object in the hot garage to make this task 100 times more easy. Shoveling sand in with a small garden spade is also annoying....FYI. Once it's full and ready to go, the bag is well made. It's very sturdy. The stiching is great and doesn't feel at all like it will rip. In the end, I'm VERY HAPPY with it. Just...get a funnel.

I only saw this base mentioned in the comments on other bases from this company but obviously it’s the best option because it holds full bags of sand - no pouring or mess! I filled it with $2 bags of play sand from Home Depot. I went with a sand base as this was about $27 while water bases seem to start at $60. I also saw reviews that made it seem like water bases are hard to fill. They’re also 4 pieces that don’t have handles so harder to move around a patio (that flexibility is one of the reasons I wanted a cantilever/standalone umbrella in the first place) and this base has nice handles to move them around. It was definitely a squish to fit the full bags of sand inside. If the cases were a drop bigger it would be perfect, but I got them in and they look sturdy and of high quality canvas. Very happy with it and it held up well in a light wind today. The base didn’t move at all, which made the umbrella feel secure. FYI I went with this umbrella which seemed to be the cheapest on Amazon from those that had several thousand 4-5 star reviews Best Choice Products 10ft Offset Hanging Market Patio Umbrella w/Easy Tilt Adjustment, Polyester Shade, 8 Ribs for Backyard, Poolside, Lawn and Garden https://www.amazon.com/dp/B0863D7W3Z/ref=cm_sw_r_cp_apip_cL5JfMjYEZHWm

We bought two orders (total of 4 of these) to use on our large umbrella base. These are easy to use. We bought 1 order (total of 2) and used them a year. Left them out over the winter - didn't move them. And they still are looking great. Had a big gust of wind and decided to place another order to add 2 more for the umbrella base. That umbrella is going nowhere. We bought 50 lb bags of playsand (one for each Gravipod), unzipped the Gravipod, placed the sand in (unopened), zipped it up and used the two handles to carry it to where we wanted. So easy. Didn't open the sand and it works great! Highly recommend!

We are a rental company and are glad that we finaly have a solution for the umbrella bases beiing one of our logistical chalences. Our empoyees now do not have to carry the heavy "one piece" bases anymore. We now use a base plate of 10 kg plus the weigt bag. Also our clients like it including the look.

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.

Holds umbrella very well. I’m very happy with this product.

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.

Brilliant item 👍
