I need something like this for my office and storage on the 4th floor, but
needs to handle more than 200 lbs.

Haven't seen the video but make it with pieces twice as thick.

OK, I saw the video. *If 4 ropes are 200 pound test each, why is the
weight limit 200 pounds. *Don't put all the weight on one corner.

It's the old "no chain is stronger than it's weakest link" theory. I

That applies when the links are all in one chain, all in a row, or in
this case all the weight is in one corner.

If one puts 200 pounds on a platform with 4 ropes at the corners, if
the center of gravity of the load is in the center of the platform,
the load on each rope is 50 pounds. *The closer the center of gravity
is to one rope, the greater load on that rope, but unless all 200
pounds are at corner A, the load on rope A is less than 200 pounds.

wouldn't want to test it. Just get some better rope.

I agree. *
