Not only does this need at least one more stabilizer bar, they all need to be a lot sturdier. Mine has bowed out on both sides. So much so that I pounded stakes in the ground on each side to be safe. Very unhappy with this but too much work to start over...
I love the concept but not satisfied with the product. The walls are thin and the stabilizing bar inside pulls the walls in. We thought the soil would push the walls out but it didn’t.
Metal strip for stabilizers is thin cheap strip. Not the strength or quality I expected. Need to do a lot better on the stabilizers. Sides are fairly sturdy.
