Oh I could definitely fall in ours and I have quite a fat ass, not sexy fat I’m just fat. Also it’s not strength, it’s balance. I lift my husband from bed to wheelchair etc daily, my legs are plenty strong. That’s also why he never leaves the seat up. If I were to fall in, it’d be my own fault. I’m going to try to find a link to my toilet, it’s pretty new if I can, I’ll edit.
