Ergonomic and Design Theory

The Mirra was designed to meet five criteria: support, comfort, diversity, durability, and environment. Mirra has a shaped backrest that follows the lumbar curve and the PostureFit system supports the pelvis to prevent slouching. The Harmonic Tilt mechanism is designed to allow the user to keep moving in the chair, which will help prevent back pain. The forward tilt mechanism is available to release the chair into a more forward tilting position for typing with your back at a 90-degree angle to the desk.

For comfort, the Mirra addresses the two main underlying issues: pressure distribution and thermal control. The seat is design to reduce pressure spot on the sitting bones, and the pressure is further reduced when reclining as is recommended from time to time. Both the seat and the backrest allow air to flow freely and keep both the lower and upper parts of your body at the same ambient temperature.

Erik: #herman_miller_mirra I just picked up this chair at a local store after comparing it with the Aeron and Embody. I was surprised how much more I liked the Mirra over the Aeron. Going in, I was fully expecting to buy an Aeron, so I was pleasantly surprised by this chair's performance. I always have lower back issues and require a lot of lumbar support so this chair suited me perfectly.

It is fully adjustable so that you can make it such that it's ideal for your size, weight, shape and personal preference. I have only been using it this morning, but already my ingratiating back pain has been replaced by back bliss. If you are unsure about splurging on a good chair like I was, I can assure you that it's well worth the money if you spend 7-8 hrs per day sitting (and coding).

FYI, I was considering the Herman Miller Aeron, Humanscale Liberty, and Steelcase Leap as my primary options, and I ended up getting the Mirra after some trial. I don't recommend you buy a chair without trying it out in a store. You might be surprised what choice you come home with. Jan 16, 12

    Erik: So I've been rocking this chair for almost 4 days now, and I love it even more. I pulled a very long day yesterday and I swear I was able to work for 1 or 2 more hours comfortably because of this chair alone. I've been comparing it to the Embody since we have one of those in our office on loan, and the Mirra is just that much more ergonomic.

    The Embody is a nice chair that feels amazing when you first sit on it, but it simply does not provide the support that the Mirra does. I would outfit everyone in an office with a Mirra chair because it does exactly what it needs to do and not much more.

    It's got a great balance. I've adjust the tension knob perfectly such that if i simply lean back, my own weight takes me to any angle without "bottoming out" if I decide to fly back all the way. Jan 19, 12
