The FlexiSpot M7 Series sit-to-stand desk riser is designed to convert any desk size into an ergonomic, height-adjustable solution. The base has a narrow footprint of only 14.8"D so that it can fit in tight spots. There are six different widths available, from 28.3" up to 41.7". Adjust the height of the platform from 4.7" to 19.7" using a single lever to actuate the gas pistons. You will find the movement to be smooth, making it easy to change height in either direction. | Flexispot | | M7 Series 36"W Manual Corner Adjustable Standing Desk Converter | Black | Best Buy
