Can anyone tell me what the 2 height settings are (in inches) please? I want to be sure it'll work with our table/chairs before I buy it.

I'm just about to buy one and had the same question. The Kaboost website says: "KABOOST is designed with a choice of 2 elevating height positions (4.5" and 3.75")." Those don't seem all that different to me, but I still think it's worth a try!

Would this fit on a child's size chair like those In a preschool?

I laid one out and the smallest it will fit is 18" if you go diagonally from outside of legs. Hope this helps.

what are the dimensions that the Kaboost has the capability of EXPANDING to be? We have wide chairs at our dining room table.

We have a chair with standard size of 15 inch by 16inch (length by width, not diagonal). I tried to pull the kaboost by extra 4 inches, it looks just fine.

What is the length it can stretch?

I purchased this for use on a bar stool so my granddaughter isn't so tempted to kneel while at the kitchen island. The bar stool legs measure 24 inches diagonally from leg to leg. On occasion when we need a taller chair at the dining room, we switch the Kaboost to one of our dining room chairs, which are quite sizable chairs. Those chairs, when measured diagonally across the legs are 29.5 inches, and it appears it would extend another 2 to 2/5 inches. If you pull it too far there is NOT a break or a stop, but the leg pulls apart and you can see the spring/cables inside. I would take care not to pull it to the max just in case! By the way, my daughter and son-in-law initially scoffed at this purchase, but soon realized it was a genius design that has worked really well. Once on the bar stool, it is more stable and less likely to tip if my granddaughter starts to move around and change positions. In addition, it is strong enough that when you don't want to remove it from the bar stool an adult can still sit on the stool if they don't mind the extra height. Hope this helps.
