I personally would think not, I've jumped my uncoordinated horse over it a tonne, and he's knocked it with no hassle, the chairs don't get in the way and personally I would think there's no chance of it hurting me or my horse more than any other jump would.
Apparently others disagree as I've had three people tell me that I deserve to have my horse taken off of me for putting him in so much danger? :-(
