Base for stability ball

I’ve been trying to figure out a way to sit on my stability ball at work. Although I own the biggest sized ball on the market, it’s still a little low for the desk. Additionally, the ball rolls away every time I stand up, which is often. I needed to figure out a way to raise the ball up a bit and also keep it where I put it. They sell bases for stability balls, but at close to $100, they are a bit pricey for me.

I tried several different options to raise up the ball…but none of them were very effective. That is, until I filched a furniture dolly from the facilities department. This dolly was built in the shop at the school of music and is very rudimentary. It works great, but I know they’re going to want their dolly back. So, I decided to make my own stability ball dolly.

Base for stability ball

A 2×4 piece of wood
4 caster wheels
8- 2 1/2″ #10 wood screws
16- 1 1/4″ #12 wood screws (or as appropriate to attach your casters)
Measuring tape
Straight edge
Power drill
Power screwdriver

1. Measure out four equal lengths on the 2×4. I wanted a 12″ space in the center, so I cut out 4 pieces that were 19″ each (12+3.5+3.5). By the way, a 2×4 is actually 1.5″ by 3.5″. Keep that in mind when you’re deciding your measurements!


2. Layout your pieces into a basic square.


3. I suggest drawing in the screw holes and outline of the casters. This way, you can avoid screwing the wood together where you then plan on screwing your casters in. Also, you’ll have a nice pattern for later on…


4. Pre-drill two holes. I did mine slightly on the diagonal and inside the area where the casters will later be attached.


Pre-drilling the holes is really helpful. It makes the screws go in nicely and keeps from splitting the wood. I strongly recommend using the right tools! That means a power drill and screwdriver! Of course, that’s only if you’d like to have feeling in your hands the next day. I bought my drill at a yard sale NEW for $30! Someone else’s folly was my boon! The screwdriver was also a similar steal…I just don’t quite remember the details of that purchase!


5. Using the 2 1/2″ long screws, attached the sides to the bottoms. Attach all four pieces together.

6. Pre-drill the holes for the casters. See why it was a good idea to draw the outline AND the screw holes earlier?


7. Attach the casters using the 1 1/4″ screws.


8. Rinse, lather, repeat for all four casters.


The finished project:


I suppose you could paint it to make it more attractive. I’m not too worried about it, since it’ll be hidden under the ball.

Here it is at work:
