X bases are so logical for convertible standing desks; it is such an easy solution for getting different heights. Danish design firm KiBiSi have created the X-table, a hand-cranked convertible desk and it is elegant and simple, one of those solutions that make you wonder why one would do it any other way.
The designers write:
XTable is a manually height adjustable desk. A piece of office machinery that accommodates multiple working positions and daily reshuffling. XTable uses manual kinetic power instead of electricity for height adjustments – saves energy and keeps users active. All technical features are constructively integrated in the table top. It uses a century old principle known from carjacks, ironing boards and other iconic tools. The principle coupled with a desk is a radical redesign of the traditional office desk. XTable is designed with an optional storage solution for office supplies and other belongings.
