Query: This thing is going back!

I bought this walker, and after putting it together I immediately had misgivings about it. It didn't seem very stable, and I was right. When my 9 month old son tried to use it to pull up it flipped over backwards. Luckily, since I had my suspicions about it doing just that, I was standing right behind him and able to catch him.In addition to tipping over, withing 1/2 hour he had the two "mailbox" panels pulled off the front of the activity area.I've already disassembled the walker and put it back in the box; it's going back to the store.
