Okamura Contessa II vs Herman Miller Mirra 2: Which Should You Buy?

Intro

The Okamura Contessa II and Herman Miller Mirra 2 both target professionals willing to invest in long-term comfort, but they take different paths. Okamura's Japanese flagship costs $2,040 and emphasizes executive refinement—integrated headrest, polished aluminum, premium materials. The Mirra 2 undercuts it by $440 while earning stronger user ratings and a longer warranty. Both offer 4D armrests and lumbar support; the real question is whether the Contessa II's extras justify the premium or if the Mirra 2's proven value wins out.

At a glance

Okamura Contessa II — strengths & weaknesses

Strengths:

• Improved circulation and posture. A user switching from a 15-year-old Aeron noted dramatically better blood flow and a "refreshing feeling" after sitting.

• Excellent lumbar support. One reviewer praised the chair's enveloping comfort and lumbar design, enabling extended sitting without lower-back strain.

• Convenient armrest-mounted controls. Adjustments for backrest lock and height are accessible while seated, a thoughtful ergonomic touch.

• Premium material choices. Mesh, fabric, and leather options let buyers match aesthetics to their workspace.

• Well-suited for women and smaller frames. A designer with chronic neck issues found it particularly accommodating.

Weaknesses:

• Limited online review volume. Multiple reviewers noted difficulty finding detailed feedback before purchase.

• Mixed fit experiences. One user reported unusual pain when adjusting seat height, and another found the Aeron more comfortable despite the Contessa II's reputation.

• Higher weight, less portable. At 28 kg, it's 9 kg heavier than the Mirra 2, making moves or reconfigurations more cumbersome.

Herman Miller Mirra 2 — strengths & weaknesses

Strengths:

• Proven pain relief. A buyer suffering back pain from inadequate chairs called it a worthwhile investment after a full year of daily use.

• Stays cool all day. Multiple reviews highlight the TriFlex polymer back and AireWeave seat for keeping users comfortable during long work and gaming sessions.

• Extensive customization. Adjustable lumbar, tilt limiter, arm options, and color choices let users dial in fit and style.

• Strong overall ratings. At 4.3 from 12 reviews, it outscores chairs that cost more; one tester called it "possibly Herman Miller's best chair."

• Lighter and easier to move. At 19 kg, it's nearly 50% lighter than the Contessa II.

Weaknesses:

• One seat size only. Unlike the Aeron's A/B/C sizing, the Mirra 2 can feel too small for taller or larger users, risking posture issues if fit is off.

• Hard seat-pan edges. Some users noted discomfort along the front edge during extended sitting.

• No headrest option. Buyers who lean back frequently or want neck support must look elsewhere.

• Price creep. One three-year owner noted the chair's cost jumped over 40% to $1,300 (though our current data shows $1,600).

How they differ

Headrest and executive presence. The Contessa II includes an integrated headrest and a taller backrest (62 cm vs. 58 cm), making it the clear choice for users who recline often or want neck support. The Mirra 2 has no headrest option at all.

Breathability vs. cushion. Mirra 2 reviews consistently praise its cool, breathable TriFlex back and AireWeave seat. The Contessa II uses high-density foam and offers fabric or leather upgrades, which can feel more luxurious but may retain more heat.

Fit and adjustability. The Mirra 2's single seat size and hard edges drew criticism, yet its adjustable lumbar and tilt limiter won praise. The Contessa II has a slightly larger seat (45 cm × 52 cm vs. 43 cm × 51 cm) and fits taller users (up to 198 cm vs. 195 cm), but some reviewers still reported fit issues.

Price, warranty, and ratings. The Mirra 2 costs $440 less, ships with a 12-year warranty (vs. 10), and scores 4.3 vs. 3.8. The Contessa II's premium lies in materials and the headrest, not proven user satisfaction.

Weight and portability. The Mirra 2's 19 kg frame is far easier to move than the Contessa II's 28 kg build—a real consideration for renters or office reconfigurations.

Who should buy which

Buy the Okamura Contessa II if:

• You're 180 cm or taller and want a headrest for reclined work or calls.

• You prioritize executive aesthetics—polished aluminum, premium leather or fabric—over maximum breathability.

• Armrest-mounted controls and Japanese precision engineering appeal to you.

• You've had success with Okamura chairs before or specifically need the enveloping lumbar design some reviewers loved.

Buy the Herman Miller Mirra 2 if:

• You want the best-rated chair in this matchup at a lower price.

• Staying cool during 8+ hour days matters—its breathability is proven across multiple reviews.

• You're 165–190 cm and the single seat size will fit (test if possible).

• You value a 12-year warranty, lighter weight, and Herman Miller's service network.

• You don't need a headrest and prefer extensive lumbar and tilt customization.

The verdict

The Herman Miller Mirra 2 wins on value, ratings, and real-world comfort reports. At $1,600 with a 12-year warranty and a 4.3 rating, it delivers pain relief, all-day breathability, and extensive adjustability without the $2,040 ask. The Okamura Contessa II earns its premium only if you're tall enough to need the headrest and backrest height, or if you're drawn to its executive materials and fit. For most buyers—especially those working long, warm days or gaming after hours—the Mirra 2 is the smarter buy. If you're over 185 cm and recline often, spend the extra $440 on the Contessa II; otherwise, pocket the savings and enjoy Herman Miller's proven track record.
