Hi! Tipping over is a common problem for BA and I've tried every possible method to get this bag to stay upright. I tried storing it with unused phone to weigh down but it always managed to tip over. Next I tried storing with stone coasters but I notice the middle part sagging a bit and over time I was afraid that it would be permanent so I removed it right away. Long story short, what I ended up doing is I just stuff the strap and air paper inside and just use rolled Chanel ribbon under the front pocket to level the bag as in the photo. Hope this helps.
