What is the difference between a 2-stage and 3-stage sit-stand desk lifting column?

A 2-stage lifting column has two telescoping sections and typically provides a height range of about 18"–20" (e.g., 28" to 47"). A 3-stage column has three telescoping sections and achieves a wider range — typically 22"–24" (e.g., 22" to 48") — making it more versatile for users with very short or very tall needs. Three-stage columns are also usually more stable at maximum extension because the additional stage reduces the column's effective cantilever.
