Question: Can I add wheels to this base to turn this+ball into a "chair"? If so, what size wheels?
Document: Received it on time and cradles the balance ball perfectly. I will probably add some wheels, so I can use it as a chair as someone else did.
I orderedWire Rack and Small Cart 3" Caster Kit - 4 Pack - 3/8" x 1-1/2" Threaded Stem. Make sure your wheels swivel! The stem on these is 3/8" and uses coarse (size 16) threading.
Maybe I missed the point, but all this really does is keep the swiss ball from rolling around the floor. I guess you can slip elastic bands beneath it and sit on the ball while working out with the bands ... except it doesn't come with any bands and how one would get the bands through the holes is beyond me. It adds no height, has no wheels, and cannot be used to add wheels.
This ball paired very well with my 75" stability ball. I use my ball + base at work (replacing the conventional chair) - and let me tell you, the base is essential! Good color, good size, shipped in time...not too heavy either.
After reading previous reviews, I ordered the base and then went to my local Lowes store to purchase wheels, nuts and washers. Works OK, but I like my Gaiam chair better.
I bought this for an exercise ball I use as a chair in the office. It performs its job at not letting the ball roll around on the floor, but the piece itself is difficult to make small adjustments on a carpet floor. Would be perfect if it had wheels, but then the whole purpose of keeping the exercise ball in place would be moot.
This is good for keeping an unwieldy exercise ball from rolling around. I use an exercise ball as my chair at work and this is nice for stowing it when I get up.I tried adding wheels to it as another commenter suggested, but found that it wasn't really suitable as the wheels got stuck in the rounded nooks where the screw holes are and it didn't roll freely.
This is a very simple product that fits the description and works well for a ball base. It would fit the larger size balls better than the 65 cm size, but is sufficient.
I used this to turn my ball into an office chair. It works well, though sometimes it does roll partially off. I've never slipped or fallen though.
This is a great base for your exercise ball. It keeps it from scooting out from under you, but doesn't restrict the necessary movement of the ball as you go through your exercises. It is minimal in height, so doesn't add to ball height profile. It is made out of firm plastic that will last a very long time - longer than the ball itself.
Answer: yes
