I have a Casio Privia 160 and had the single crossbar stand. It rocked when I attempted to slide in on the chords. With this stand there is not any movement at all. It is rock solid. Set up was a snap. It took maybe 5 minutes including adjustment time. The straps seem to be useless for me though I have yet to flip my keyboard over and verify. My first look did not show any obvious connection points. I have had it about a month and play at least an hour every day. I have carpet and have simulated a hardwood floor by placing small pieces of 1/8" Masonite almost the exact size of the bottom piece under each bottom leg of the stand. Even without these there was virtually no rocking. This is a well made product despite what I have read on some of the negative reviews. You will not be disappointed purchasing this stand.
