It’s made from PVC and comes with a pump and tape measure to help with inflation and sizing. Available in 55cm, 65cm, 75cm, and 85cm sizes, it can be used for yoga, Pilates, stretching, and other home workouts. It can also serve as a chair or a ball for prenatal exercises, choose a size that suits your intended use. ## Highlights This stability ball adds an unstable surface to exercises such as crunches, bridges, and dumbbell workouts, which calls for more balance and core engagement than doing the same movements on a firm floor. It can also be used for sitting or stretching, so it may suit someone looking for one piece of equipment for several kinds of movement rather than a tool for a single exercise. The PVC ball has anti-slip lines and an anti-burst design. The manufacturer says that if punctured, it is intended to deflate gradually rather than burst suddenly. That design is not a reason to use it around sharp objects: the product information recommends a large area free of obstacles. Its stated weight capacity is 250kg. Buyer feedback is generally positive about ease of inflation and use, and some buyers say they use it for workouts and stretching. Reports are mixed on air retention, durability, and whether the ball matches its advertised size. Those varying experiences make it sensible to pay attention to inflation and sizing rather than assuming every unit or fit will be the same. ## Practical tips The included pump and tape measure are useful for setting up the ball at home. The manufacturer recommends inflating it to 80% of its recommended size, leaving it for 24 hours, and then finishing inflation. Its size guide is intended to help match the ball to your height and workout, because the available sizes vary, check the chosen size before ordering rather than treating them as interchangeable. Use the ball on a clear, smooth surface and keep it away from obstacles that could puncture it. The product information does not provide specific cleaning instructions, so avoid assuming a particular cleaner or care routine is recommended. ## Usage tips For a home routine, the ball can add a balance challenge to bridges or crunches, or provide a surface for yoga and Pilates movements. Start with exercises where you can control your position, and leave enough open space around the ball. As an office chair alternative, it changes the way you sit, but it is still a round exercise ball rather than a conventional chair with a fixed seat. A solid pick if you want a multi-use ball for home fitness, stretching, or sitting and appreciate having a pump included. Not the best choice if you need a fixed-size seat or want a firm, stable platform, the ball is designed to create instability, and buyers report differing experiences with its size and air retention. ## Questions before you buy **What sizes are listed?** The product is offered in 55cm, 65cm, 75cm, and 85cm sizes. Use the size guide to choose for your height and intended workout. **What comes in the package?** The product information lists a pump and tape measure to help with inflation and sizing. **Does it stay inflated indefinitely if punctured?** No such guarantee is stated. The anti-burst design is described as allowing gradual deflation after a puncture, and buyer feedback on air retention is mixed. ## Final verdict The Core Balance ball makes sense for someone who wants one piece of equipment for balance-focused exercise, stretching, and occasional sitting, with several sizes and a pump included. Its intended instability is useful for those workouts but does not replace a fixed chair or a stable exercise surface. Since buyers disagree about fit and air retention, selecting the size carefully and following the stated inflation steps are practical parts of deciding whether it suits your routine. ## Images ![Core Balance 565769-US Exercise Ball, Anti-Burst PVC with Pump, 55–85cm — 1](https://www.ofertitastop.com/i/_sEBPCvTIuTWzb6uxB5EiYkIUidGwD7BkuWIS2oR4c2D96qs_NXHsq-SIM6vhG2iZBGvZ_VKJpUb04rsy5uYVYQ6ZLpCYxH6ArSvrG2zwbDOW_-ajg3io_GgqA.jpg) ![Core Balance 565769-US Exercise Ball, Anti-Burst PVC with Pump, 55–85cm — 2](https://www.ofertitastop.com/i/no1DwTQsafU4XEoZn2kN-NpPUeBHq5e9tVWDO7ArtYlxtfe-nQ5c6LJnh6_A-861lvnbyJVSChw15zbhKUhJsrJXgghadFDxFFBT85eM5kjkoYQ1T0yHOhi9Qw.jpg) ![Core Balance 565769-US Exercise Ball, Anti-Burst PVC with Pump, 55–85cm — 3](https://www.ofertitastop.com/i/kwxWy4TUGCEuO28zwSIOOy-TbMa2BvdZ_sIGRYTLQkdOLJivpoibE3LY-LTOvdMeMH0y8xTL2RilBU1jGIDDGZtxf7PeXcvP7UT_Bcx2njVoV0VvVleM-cZlAQ.jpg) ![Core Balance 565769-US Exercise Ball, Anti-Burst PVC with Pump, 55–85cm — 4](https://www.ofertitastop.com/i/xz-ptNWqvasxFL-nW9mO4crjx9SA0Hy68EPF81mxjAh6I1zD6qgAA-PACF0TKyD2l2CYKX9HvPqeUN4OE-ztUJZb9878ICDaWd1b3XegUVWHsCHPrNlCv3-fNw.jpg) ![Core Balance 565769-US Exercise Ball, Anti-Burst PVC with Pump, 55–85cm — 5](https://www.ofertitastop.com/i/F2uayRP_ptBzkpoIXsr-6oHxoQcL6_m8BIq10gLmGkXijX47QvlVPCHCUObi4zalNAukEysPa9EI2PMImepdcNlP6A_13DU_PRJvRitVV5Fmlhs4fuxsLYBxjg.jpg)
