We have one but it has the plastic spacers and rubber boots so must be a newer model or something. I can see how it could be a dnager if the kid managed to push it off certain surfaces, but you know what, the instructions clearly state NOT to use on specific types of table. On a normal solid timber four legged table with the clamps firmly tightened the seat is very stable, I have put my full weight into it and not been able to budge the clamps. It is a bit like them recalling the bumbo seat in the US because some kids fell off tables backwards, when the instructions clearly state not to be used anywhere but on the ground and to always supervise the child whilst in there.
