With the Silhouette Teacher’s Sit + Stand, teachers have the flexibility to use the desk as an add-on conference top when paired with a bullet Cascade teacher’s desk or as a mobile teacher’s lectern when pulled away. The edge of the tabletop features your choice of a bumper t-mold or 4mm t-mold, which is then fastened to the underside of the work surface every 6 to 8 inches to assure a long lasting fit. *Silhouette® Teacher Sit + Stand is not intended for student use.
