This one fits the bill perfectly in terms of size and durability and is a breeze to set up. Every chair needs to be equipped with this cup holder.

After a week of use, I no longer have to worry about it slipping and falling. My full coffee cup has no effect on it.

My wife finds it convenient because she can carry her huge smartphone or her coffee mug.

This is the best one there is. It won't budge from its target.

This cup holder is fantastic, by the way. The quality is excellent, and the cost is reasonable.
