Happy bench building folks. I hope you make it your own and not worry too much about what someone else thinks it should be. Use the rules as a guideline, they have validity, but make it your own in the end. If the rules fit you that’s great, if they don’t quite fit you then make it to fit yourself. It’s you using it, not some guy making a nice living off of telling you how he thinks you should do it. One size does not fit all. Never has, never will.
While a strict figure for the bench’s weight capacity is not available, a quick browse through their other stand and bench products shows a general weight capacity well above most other brands. As such, while we cannot say for certain that this bench provides the best weight capacity, it is more than likely that it the capacity is similar to the other products in the catalog.
