Title: Fitness Ball Chairs
Post by: digitalleftovers on Thu, 14 April 2011, 13:02:44
Someone brought one of these into our offices on monday, and now the whole company is in a frenzy over them.  Our company doesn't offer choices in chairs, so these seem to be a good compromise between ergonomics and price for people who want to buy their own.  Atleast one other person has purchased one this week and I suspect there are more to come.

Any thoughts about this product or products like it?  Is this a good ergonomic option?

Note: Even though this is Amazon's product image, the ball sitting in this frame is overinflated for what the company recommends.  There needs to be a divet in it when you sit on it. they include a measuring tape so you can get the correct circumference.

All I can say is, this most certainly ain't a fitness chair:

the pettibon system is a better suit for office excercise.

comfy is not practical

The ball makes you work a little to retain your balance and sit upright? Is that the idea? It sounds like an interesting theory. I'm not sure how well it would work in practice. It seems like the frame and the backrest defeat the purpose at least partially. I have spent one or two hours at a time sitting on a bare exercise ball while watching movies, and it was neither unpleasant nor heavenly.

If you suffer from back pain, as I did some years ago, I think the second best thing you can do is to dispense with a chair and work standing up. The very best thing you can do is to strengthen your back through regular exercise.

Having a sitting ball fixed by a construction around it defeats the point of having a sitting ball: To keep your muscles active for balance. If the ball stays put without any work, you can just return to slouching.

Yes, I recommend the ball. But without anything extra.

the pettibon system rotates in 3d.

I too recommend using the ball without the rolling fixature. It's bouncier that way and if you want to keep the ball from rolling away, just use something like that

As said before, the whole point of this ball is to keep you in motion during work to prevent back problems and such.

They're offering something similar on amazon

kneeling? THIS technique does not need your backside...

No, I kneel vertically - and my ass is not on the ball - but that gets uncomfortable pretty damn quick.

Although it should prevent slouching in the 1st place, it's still possible as this man proves

Those balls may pop if the same spot is always on the floor, which might explain the ring. There was a Youtube video of someone using a plain ball and then just suddenly ending up on the floor. I wish I could find one now, but it's all just dumbasses intentionally popping them.

I've been owning one for ages now and you'd really have to pump it up till its limit and put it on the same spot all the time. Otherwise, I have never heard of one popping and I know a couple a people who are using them.

I used a ball (without the chair bit) for a while.  Makes a nice change but I'd recommend that you keep your existing chair as well.  When your core muscles get tired you'll just end up slouching on the desk.

I've moved to an ergotron sit to stand solution - works far better (for me) than the ball.

I read a medical study some months ago which stated that sitting inproperly on this causes spondylosis (not what you want when your back is already aching). I can't find it just now, but should be on Google.
Better get a knee chair.

I cant stand no back support. It would be useful to throw at people though...

Kneeling charis... I remember those.  I missed the back support on them as well, but a well made version can be compfortable.  I don't think I have seen anyone use one since 1995.  Does anyone here (http://ecx.images-amazon.com/images/I/81DZI96ixlL._SL500_AA300_.gif)use one?

I don't think I could use a contraption like that. Well, maybe, I do slump at times.
Is there really any comfort involved? I like to lean back a little.

If you lean back in a knee chair, you fall over. I had one once; it wasn't pretty.

If I recall correctly, you must sit up straight in a kneeling chair.  If you don't, then you put too much pressure on your shins and cut off circulation (because your shins actually rest on the knee rests).  Perhaps that was an intentional feedback mechanism?

The research cited on wikipedia is not conclusively favorable of the kneeling design over a conventional chair.
