What is 2D armrest,3D armrest and 4D armrest?

<1>2D, 3D, and 4D are an example of some nifty jargon that you see in the Ergonomic Office Chair world but it is often not explained which makes the constant reference to it quite unhelpful.

 

It simply refers to the number of dimensions the armrest can be adjusted. As a general rule of thumb, provided the build quality is good, the greater the adjustability the better.

 

So when we are looking at a 4D armrest, the adjustments which will be available are height,pivot or rotation inwards or outwards, an adjustment in or out from the body(to increase or decrease the width), and forward and back. If you are looking for a chair with 4D capability then the Hero is ideal.

 

In our view,most users will get more than enough performance for their needs from a 3Darmrest, as the forward and back adjustment in our opinion is of limited appealto most, provided that the chair is otherwise set up well. The Hi chair is anexcellent example of a chair with brilliant 3D armrests.

 

When it gets to2D it is actually quite important to double-check which of the two dimensionsof adjustment are being offered so that you in fact get what you think youneed. If 2D is what you need the Owen is a classic choice and difficult tobeat.
