Raptor is different. We designed Raptor to be as comfortable as possible, for as many people as possible, without requiring you to do much of anything.

We call it body-regulated ergonomics, which simply means that when you sit down, your weight serves as the primary control mechanism. The tilt of the chair is automatically adjusted to make you comfortable.

Does that sound revolutionary?
It is.
We even have a patent on it.

Chairs like this don't just happen
 
They start with a lot of research. That's where we discovered that although tilt tension is one of the most important aspects of chair performance, people rarely knew how to set it properly. So our designers went to work devising a chair with an automatic and dynamic tilt-tension adjustment.

Here's how it works
Technically, it's called an Inverse Synchro-Tilt mechanism. All that means is that as you recline, Raptor makes two adjustments to keep you comfortable.

First, it raises the back of the seat, so you can keep your feet on the floor, where they belong. Second, it opens the angle between your torso and your legs, which redistributes your weight and improves circulation. Because your back is always touching the back of the chair, your lumbar region gets all the support it needs.

With Raptor, there are only two manual controls: tilt-range limiter and pneumatic seat height.

One more thing about how it works
We wanted Raptor to be comfortable for as long as possible so we used computerized pressure-mapping equipment to make sure that the shell distributes your weight evenly across the seat. Then we packed the seat with memory foam, a handy tool that NASA developed, to reduce the pressure on your legs and back.
