We have covered the VARIDESK Pro here in the past. It is a wonderful tool that enables you to work while you sit or stand. You can change your position quickly. The folks behind it have now improved its design and introduced the VARIDESK Pro Plus. Unlike the previous model, you get a lifting keyboard tray here. The desk has a surface area of 36″ x 27″. You still get a companion app that suggests when you should sit or stand.
The VARIDESK Pro Plus fits on most desks. It offers spring-assisted lift. With 18” (desktop) & 14” (keyboard), the VARIDESK Pro Plus allows you to get your work done comfortably. Not cheap but quite useful.
