Twenty identical trays let a studio give every color family, marker set, or sticker pack a level of its own instead of one deep bin where the yellows disappear. Each tray measures 13 in by 10 in by 2.5 in, deep enough to stand paint tubes on end and wide enough for brushes and letter-size sheets to lie flat. Trays glide on metal channels and lift free when a project moves to the easel. The 25-in by 15-in top stages a palette, a canvas panel, or a small printer, and the 18.5-lb frame rolls on four casters with two locks to hold it beside a work table.
