What We Like

  • The listing states lumbar support as present, and the title lists it too.
  • The title lists adjustable arms, and the spec details give the arm type as Adjustable.

Watch Out For

  • Build is the weak pillar: its sub-score of 3 ties for the second lowest among home office chairs, with the warranty earning 3 of 9 points and weight capacity, certifications, owner rating, base and gas lift all at zero.
  • Its 3.7 average ties for the third lowest rating among home office chairs that state one.

At a Glance

The Herman Miller Mirra is titled as fully featured, with adjustable arms, lumbar support and a FlexFront seat.

Who This Chair Is For

  • Shoppers who want hard floor casters, which the title and the spec details both give.
  • Buyers who want a mesh back upholstery, which the spec details give.

Who Should Look Elsewhere

  • Buyers weighing cost against comfort scores: the displayed price is the sixth highest among home office chairs, yet the Comfort Index of 12 ties for the third lowest.
  • Anyone who wants a deep owner track record: 43 reviews is the twelfth smallest review base among home office chairs that state one.

FlexFront seat, forward tilt and upholstery for the Herman Miller Mirra

The title names a FlexFront seat, forward tilt and a tilt limiter; the fields give the seat upholstery as synthetic over a foam seat material, on hard floor casters. The listing does not state a recline angle, a tilt tension control or a seat height range.

Alternatives to Consider

Why consider: Gives a 5 year warranty against 3 years here, along with a center-tilt mechanism and a tension adjustment.

Why consider: Names a BIFMA mark and 3,657 reviews, where this Mirra lists no certification and has 43 reviews.

Frequently Asked Questions

How tall is the Mirra backrest?

The backrest is 24 inches tall.

Is the Herman Miller Mirra still sold by the manufacturer?
