Just measure how wide it is when fully open, count the number of ribs, and search for replacement covers that fit those parameters. More on reddit.com

I just bought a Högön umbrella with the Svartö base for a rooftop patio. It’s been up for a week and so far so good, I keep it closed when I’m not up there. You will need two 50 pound bags of play sand or something similar to fill up the base and weigh down the umbrella. It swings a bit but not wildly. The vents at the top help to keep it from blowing around. The top half of the umbrella is secured with a few screws so it could be removed pretty easily in preparation for foul weather.

Having gone thru many an umbrella my advice is it’s not a thing to spend a lot of money on because freak storms don’t care if u spent $50 for it at Walmart or $5000 for it at jardin de ville. Better off putting your money into the patio furniture and considering the umbrella as a short term item. My 2 cents! (And no I didn’t pay $5000 for an umbrella 😝) More on reddit.com

I have a super cheap patio umbrella and simply bringing it in whenever I am not using it has allowed it to last 10 years. No point in leaving it to battle the elements if it isn't in use. I paid $30 for it at a discount store. More on reddit.com
