Laminate Desktop Elevator
The Desktop Elevator is an adjustable height surface that is easily placed on top of your current desktop. This is a great choice for those who are not able to replace their current desk with a full sit to stand unit, or do not want to be burdened with assembling a whole new desk. It effortlessly raises and lowers to 14 positions using nitrogen gas pistons, making this a convenient and electricity free ergonomic workstation. The Desktop Elevator comes in Yorkshire Cherry, Wild Cherry, Kensington Maple, Fashion Grey and Natural Almond, and is available in either 24'' or 27'' depth models, so you can easily accommodate different sized desks with an elegant look.
