Hi Doug,
I don’t own one but I have talked with the manufacturer and various retailers about them and they are Knickerbocker’s strongest bedframe (even stronger than the Knickerbocker Monster which would work for anyone) but it also carries a very high price that is more about its appearance and aesthetics and would be difficult to justify unless the appearance was important to you.
There is more about steel bedframes including several heavy duty versions that are in much lower price ranges in post #10 here.
