It is poorly manufactured. Blocks dont align and are off center. Absolutely do not trust the strap to secure it to the wall. We tested it and the fabric ripped and broke loose. We replaced it with a wire one we bought at the store. Product isnt worth investigating in. Honestly the only reason we kept it is because it would have taken more effort to break it down, box it up and return it. It serves its purpose (outside of the failed safety strap) bit isnt great quality.
