High rise mini rolltop desk is a great desk design when floor space is at a premium or you just need a compact desk. It is based on our High Rise Standard and is really a High Rise Standard slimmed down to a single rack width (outside width is just 21 inches!). There are 10 rack spaces below and 3 above the tabletop. Plus, the rack rail above the tabletop is removable if you need a tall clearance for things such as video monitors.
