I have that one too. The feet are adjustable, mine wobbled because they needed adjusting, but I also placed a small rug under it and now no more wobble. If yours is the top wobbling on the stand, perhaps loose screws under the top? If it's the moveable part, it could just be defective and need replacing.What I find annoying is the way that it collapses to form the bed, but it's mostly just my wife and I so not usually a problem. If no longer on warranty, you might look for a replacement that has the two posts and mounts to the floor, then fabricate two shorter pipes for holding the bed when needed.
