Sitting all day is bad for your health. People with sedentary jobs have a much higher chance of heart disease than those who move around more. The wobble seat provides a solution similar to the Locus Seat deigned by Focal Upright Furniture (www.focaluprightfurniture.com) without breaking the bank.
This seat should be used with a stand height desk or drafting table. (Note the tabel in the first photo of the seat in use is not quite high enough, sorry.)

Do you have measures of the Concrete basis please ? Il would try to make it in autocad to fit to my taste :)
Thank you !
Excellent I really like this idea and will be making something similar when I get a moment.
I particularly like sitting this way when working on fine practical or drawing tasks.
Some of the old timers used similar "chairs" at the crap tables in Las Vegas for many years. I think they might have all died now though because I haven't seen any of them around in a while. They would have appreciated the large wobble, low center of gravity base improvement because it wouldn't fall down when they got excited and jumped up. Would need to be a lot lighter than concrete though to be portable. Many of the guys had handles for their "chairs" and used them as canes when they were walking.
Also, a thought about "rubberizing" the base.... Could you wrap large rubber bands around it until it provides both some cushion and grip? That might help for wood floors.
See the many comments above about rubberizing. There has been some really good discussion about it.
The only thing that concerns me is that on some floor surfaces it could be prone to sliding away, I would hate for all the health benefits to be cancelled out by sudden & painful contact with the floor :-(
Perhaps some anti slip covering suitable for the surface it's to be used on would be worth considering.
It's actually a bit more like a ball joint on a car - the base is flat with a socket on top, and a ball fits into the socket.
Perhaps you could alter this design to add a concrete cup beneath - then you could simply put rubber non-skid feet on the bottom of the cup.
Make a box big enough to hold the entire molding. Fill the bottom with concrete and then press the basket ball (covered in vasoline or other mold release) into the bottom. Then pour the rest of the concrete inside the hemisphere. It should expand into a neat hemisphere.
Mark an alignment mark on the ball and the cement because when you remove it the ball will almost certainly shift and you want it exactly back where you left it. You might find that simple compression will keep it in place during use but you'll probably want to use flexible vinyl glue to make it snug.
Hmmm, just now it occurred to me that you could section the top of the basket ball like an orange and then fold those over the concrete. If put bolts in the concrete while its wet, you could then just screw down a holder of some kind. Would look ugly but it would work.
Alternatively if you were to cut car tyre strips with a chamfer & fix them into the mould before pouring the concrete they would stay in quite well on their own, cycle tyres may be even easier as you could simply cut it into sections complete with sidewall & beading fix them into the mould with a low tack adhesive & pour concrete into the lot.
