We bought this to replace our ottoman, and it's turned out to be so much more! I'd visited a house where they replaced their ottoman with yoga balls, and I loved the idea because they can also be used as seating and as exercise equipment. The 75 cm ball was perfect for my 6'4" husband and 6'2" son to sit on, and it was so comfortable for me (at 5'6") that I ordered a second one (65 cm) to switch out with my office chair. I'm a fidgeter, so it's great to sit on something that moves with me. There are videos online with exercises you can do at your desk with a yoga ball, and there are studies that claim even sitting still on the ball helps strengthen your core since you have to keep yourself balanced. The two balls that I ordered from BalanceFrom both came with a foot pump, extra plugs, and a paper measuring tape, and they were easy to fill. They have kind of a pearly finish to them, which looks nice in my house and in my office. My younger kids have used them for extreme living room sports, and they've held up with no sign of losing air. Highly recommend!
