TV-Lift
A Television-lift, TV-lift for short, or also TV lifting system, is an electrically powered mechanical system which lifts or moves televisions vertically or horizontally out of furniture, ceilings or partition walls. The main reason for using a TV lift system is in order to integrate a television into the existing interior design of a room without the television disrupting the overall design appearance. Due to the high overall project costs associated with TV lifts, they are regarded as a luxury product and are as a consequence most commonly to be found in more up-scale homes and apartments, conference rooms, private jets or yachts.
