I have two of this exact shed, plus the big, wide version with a lift-up top! I love them all. No issues whatsoever with these tall ones tipping over… but they are on my concrete patio. I have a 25lb umbrella stand in one, which I’m sure helps secure it. The other one has a lot of “vertical” items (shovels, rakes, pieces of a hammock stand) and is situated between the second shed and a set of concrete steps. Everything made it through this windy Midwestern winter. I put some faux locks on the doors (these) so just incase one did tip, something would keep the doors closed. Super happy with all purchases!
