SmarterLife Exercise Ball Yoga Ball for Fitness, Balance, Stability, or Pregnancy, Gym Ball for Core Workout, Physical Therapy, Yoga Ball Chair for Office, Anti-Slip Anti-Burst

I love this exercise ball! It’s sturdy, doesn’t slip, and feels super durable. Great for workouts, stretching, and even as a chair for better posture. The anti-burst design gives me confidence while using it, and it’s perfect for core exercises and balance training. Also works great during pregnancy for stretching and comfort. Easy to inflate and a great addition to my home gym!

I recently purchased a 65cm Smarter Life exercise ball to use as a deak chair. As I was useing it on a tile floor I put a mat under it to give it protection. All went well for about a week when to my horrorI I heard the sound of hissing air being expelled from the ball. Inspection revealed a small hole in the ball that resulted from either a defect or me rolling the ball over some sharp object (I very much suspect the latter). I e-mailed the company to ask if there was a warranty. A gentleman named Tim wrote me back asking for the amazon purchase number which I duely sent him. Shortly afterwards another message said they were sending me a replacement, no questions asked. For customer service they deserve 5 stars plus.After my first e-mail I had no idea if they would replace it or tell me to get lost. Assuming the worst I looked around on amazon for a cheaper replacement and settled on the Black Mountain ball and for further protection I ordered the Cando ball base. Having tried all three products I thought I would give a comparative review....As far as functionality goes both ball work equally well. The material the Black Mountain ball is made of seems remarkably like the beach ball you had as a kid. The Smarter Life ball seems to have more substance to the material. It seems more rubbery and thicker. The Black mountain ball claims a bursting strength of 2000 lb. Fortunately I weigh just a little shy of that so I can't put it to the test, but so far so good and I really can't imagine that the Smarter Life ball would be any less strong.Both balls come with their various but different accessories. The Black Mountain ball apart from the plugs and pump has a small fork to get under the plug to remove it should you need to put more air in it; so far I have not had need for it but in a pinch I find a flat bladed screwdriver (if you're careful) will do the trick. As for the pump, I found it perfectly adequate for the job. A lot of people complain that it's a little on the cheap side. You pump, air gets sucked in through one side and out the other and the ball inflates. What more do you want for $15.50? A motorized pump?The Smarter Life ball comes with 2 plugs, a hand pump and a tape measure. It's the tape measure I liked. Its just a strip of plastic with a hole in each end. You wrap the tape around the ball and pump till the two holes align. That's when the circumference reaches about 80 inches. The reason I liked it so much is that I pumped the ball up till I thought it was pretty darned hard and I thought it still looked small. I wrapped the tape around the ball and still had 6 or 8 inches of slack. At this stage I began to think that thet sent me either the wrong ball or the wrong tape. Their balls are color coded (65cm is purple - and a nice shade of purple) so I knew I had the right ball. So I thought I'll just keep pumping till the holes align and if the ball bursts in the process I'll complain. Well, it did not burst and it was exactly the right height for my desk as is the Black Mountain ball (I'm 5'10"). Any time you need to check the circumference or put more air in the ball you have an exact measurement.The Cando base does give me some protection. The ball/base relationship is not a tight fit so you do have some wriggle room to move about but you can't move your pelvis around and have the ball move freely on the floor Mostly if you wish to change your position in relation to the desk you have to lift your body off the ball move it and then reseat yourself. The unit is one piece and I'm quite happy with it. Hope this helps somebody decide.

Update-Revised my ratings, Smarterlife group has been wonderful to address my issue and gave me good information on how to prevent tears and they are sending a replacement! I will definitely order again.Didn’t have the ball for a day and it has a hole!!! These are not anti-burst.

Gets round with the pump, seems tough, nice color, useful for exercise, like it!

Seems to be good quality. Great for work outs.

This was a great purchase. It is exactly as advertised. It was easy to blow up and went up really quick with a hand pump. I didn’t quite get the measurements they recommended in the instructions but it seems to be the right size. It has held the air well and been used a ton!

AWESOME exercise ball!! I'm tall and have long legs. In the past, I've struggled with finding an exercise ball that's tall enough for me. But, this one works nicely!! VERY durable!!!

I recommend this product. Rubber is thick. Good quality. Perfect for my back stretches. As it turns out, it the same manufacturer that my physical therapist has.
