What Is A Counterbalanced, Spring Or Pneumatic Height Adjustable Desk?
This type of movable top desk is raised or lowered by activating a counterbalance, spring or pneumatic gas lift mechanism.
Typically there is a lever on the underside of the work surface which allows the user to alter the height of the desk top.
Where would you use this type of desk?
This type of desk normally comes in two distinct formats. First, there are larger desks which have a similar footprint to a normal office desk. These are a good choice where you need a reasonable amount of work surface for ancillary items.
Second, there is quite a wide range of smaller topped desks, mainly with pneumatic operated height adjustment. These desks have a lower weight carrying capacity and are ideal for laptop users and smaller flat panel screen use.
How do they work?
All the desks work on similar principles. By releasing a control lever it allows the mechanism to move the top up or down. With counterbalanced desks they are weight activated where a set of weights act to balance out top movement when the lever is released.
Pneumatic or spring controls work rather like an uprated office seat gas lift. Once the lever is released the user applies hand pressure to lower the desk and reduces the pressure applied to lessen resistance when raising the top.
Simple operation through a lever release
Uncomplicated working parts good reliability
Wide choice of portable and compact tops, space efficient in use
Requires no electrical supply
Relatively light load capacity, generally 100lbs maximum
Some of the tops are quite small, not much space for additional items
Larger counterbalanced units can be hard to control when altering height
Gas lift desks are the most popular desks in this category, mainly due to the increased use of laptops, flat screens and other portable devices. They also cost significantly less than many other types of sit stand desk, largely as a result of their smaller size and uncomplicated construction. So, if you are a laptop or portable device user they are worth considering.
