Reviewers say that the Herman Miller Mirra compares favorably to the Herman Miller Aeron (Est. $630), with a more modern design and comparable comfort. In fact, many owners say they opt for the Mirra over the Aeron after trying both. The Herman Miller Mirra is available in two models, basic (*Est. $600 to $800) and loaded. The primary difference between the two is in adjustability: The extra $200 for the loaded version will give you adjustable lumbar support, armrests, and seat depth, and a tilt limiter. Not surprisingly, the loaded model receives higher user ratings. Unlike the three-size Aeron, both Mirras come in only one size that's designed to automatically adjust itself to its user (thereby requiring only minor adjustments to customize fit), a feature that most owners applaud. If you want a model that's as adjustable as the loaded version of the Mirra but costs less, you may want to consider the Steelcase Think (*Est. $690), which gets good reviews from experts.
We found brief mentions of the Herman Miller Mirra at Entrepeneur.com and Inc. magazine. Owners give good descriptions of their experiences with the Herman Miller Mirra at Amazon.com and Buzzillions.com.
About two dozen users praise give the Herman Miller Mirra office chair -- the fully loaded version -- a very high average rating of 4.5 out of 5 stars. One owner writes, "The breathable weave, soft but supportive body-forming feel, and adjustment flexibility make this chair an all-day comfort experience." One reviewer warns that if you weigh more than the 300 pounds this chair is rated for, you will run into difficulties, and provides a link to a YouTube video that shows what happens.
