How does this expand and what are the three adjustable heights?

It does not expand. Height raises to 6.25 x 11. I use 3 extenders. It is able to fit 2 stackable legal folder drawers.

yes, there' are around 3 preset heights that the legs snap into as you adjust them up or down.

My brother set this up for me, so I am not positive, but it appears that there are four height adjustments at the bottom.

Yes, the height is adjustable. There are holes and a button that locks in at the height that you choose. If you look at the picture, you can see this.

Can only extend height to parameters listed. Not sure what install into previous set means...

I had measured it previously and believe it rises to over 5 foot fully extended, but it adjusts to whatever you need. One great feature is I have had the front legs long and back short so I could place it on stairs without falling.

When you assemble it, you can set the height. Then you would have to partially disassemble it and reassemble it to "adjust" the height. So it is not simple and I would not term it "adjustable.?

Height is not adjustable. It will tilt through a few degrees from vertical, though.

It's adjustable but it probably extends out 6 to 8 inches. Very nice product. Sturdy and capable of supporting a fairly large 3 ring notebook full of music.

According to my son, who was the recipient of this set up, the brackets are expandable. They vary from 3 to 5 feet.

On the one I got has a handle that pops out just above the three legs that you can twist to extend the top up to 72"

There are two adjustments for the width. It is good for narrow areas or expands for larger areas.

It's adjustable. I supplemented mine with additional length by aquiring hardware from the local store.

Use a metal straight edge to adjust the height with the supports pulled in, then extend the supports.

It's adjustable in 1/2" increments. The maximum clearance is 3 1/2". The minimum is 2".

Yes it's adjustable. I'm not sure how high it goes but it looks pretty long

It has 3 height adjustments, and yes you must disassemble (though not entirely) to change them.
