The ladder profile sets each of the four tiers a little further back as the unit climbs 52.4 in, so the deep bottom shelves carry the weight while the top stays light and open for display. Two drawers close off the base, giving chargers, batteries, and stationery a home that visitors do not see. Both open by a cut-out grip milled into the front panel, so there are no knobs to catch a hip in a narrow study. Each shelf holds 22 lbs and each drawer 11 lbs, and an anti-toppling device anchors the frame.
