Make sure the forward edge of the footrest. NEVER exceeds the front tip of the chair legs at floor level.

Had ours for eight years, and it has never tipped.

My children have tipped the chairs forward and back. However, they are older (and bigger and heavier) than 4.

Going on 7 years with two monkeys in Tripp Trapps and they've never tipped. Check the chair.

Sounds like perhaps it's not put together correctly. Did you follow the guidelines regarding how far forward the bottom footrest can be, compared to seat?

I'm a big fan of anything Stokke, and in my 8 years of having 2 Tripp Trapp chairs none of them have tipped.

However I did hear that the chair could tip backwards. Not sure what happened to make it tip forward - is it a wrong installation, or just that your DD is very athletic?

I think you might have put it together incorrectly.

We've had our 2 yrs and has never tipped- not sure what happened. Was she really pulling on the top to get herself up? Try lowering the bottom step?

Just gave my 4-year old the Tripp-trapp chair, and she stepped up on the bottom foot rest with one leg to get up onto the chair part, and the chair tipped completely forward! If I hadn't been standing right there, the whole chair would have fallen top of her. I installed the anti-tip plastic extenders for the back legs, but that is for preventing it tipping backwards. Is this just a dangerous chair, or did I put it together incorrectly?
