However, due to their high price, they have failed to catch on until now. Recently, Ikea has brought out Bekant convertible(可變換的) standing desk that can bee a normal desk at the touch of a button. The $500 adjustable desk can transform from a standard desk to a standing one, and Ikea hopes it could make the standing desk mainstream. Experts say that changing from a seated to a standing desk can improve productivity. Similar desks have bee a mon sight at tech firms such as Google, where some employees have even installed treadmill (跑步機) and bicycle desks. The desk is not the first convertible on the market.

The desk can even be programmed to move up and down slightly, making it appear to take a gentle breath to remind the user to change their positions. To move between sitting and standing positions, owners simply double tap on the screen. The desk can learn the user39。s preferences over time and suggest the best seating position. The Stir Kinect desk was created by a team of exApple and Disney engineers. It has a builtin touch screen to control and track movement, and can tell users exactly how many calories they burn by standing during their working day. It also has devices containing power points and USB ports for charging phones, to keep cables hidden. Ikea39。s heightadjustable desk is great for opening up the lower end of the market, said JP Labrosse, founder and CEO of Stir.（1）What is the text mainly about?
