Tested & Reviewed by Dennis Robbins (Mesa, Arizona)
If you’re hunting for a straight answer to the sihoo m59as ergonomic office chair review question, here it is: the M59AS Dual is a genuinely comfortable mid-range chair with a smart dual-backrest design that supports long workdays. I spent weeks testing it in my Mesa home office, sitting through spreadsheets, video calls, and marathon writing sessions. I judged it on lumbar support, adjustability, build quality, and how my back felt after eight hours. This sihoo m59as ergonomic office chair review covers what worked, what didn’t, and who it truly fits.
Key Highlights & Real Specifications
- Dual backrest with adaptive lumbar support that moves with your spine instead of poking at it.
- Breathable mesh back, adjustable headrest, flip-up armrests, and a tilt mechanism for reclining.
- Sturdy nylon base with smooth-rolling casters, rated for everyday home and office use.
What I Like
- The split dual-backrest flexes independently, so my lower back stayed supported even when I leaned sideways to grab a notebook.
- The adaptive lumbar piece follows your posture rather than forcing one rigid position, which cut down my mid-afternoon slouching.
- Flip-up armrests let me push the chair fully under my desk, freeing up floor space in my small office.
- The mesh back stayed cool through Arizona afternoons — no sweaty back after long calls.
- Assembly took me about 25 minutes with the included tools, and every screw lined up without fuss.
What Could Be Better
- The seat cushion is on the firmer side, so if you prefer a plush pillow feel, it may take a week to get used to.
- The headrest is adjustable but sits a bit high for shorter users unless you angle it carefully.
- Reclining tension is controlled by a dial underneath, which means reaching down to fine-tune it mid-session.
What Real Amazon Buyers Are Saying
- “The lumbar support is the real deal — my lower back pain eased after the first week of use.”
- “Solid build and easy assembly, though the seat is firmer than I expected at first.”

My Personal Hands-On Experience with M59AS Ergonomic Office Chair, Dual
In my daily use, this chair handled a demanding schedule without complaint. I start work around 7 a.m. and often sit through back-to-back calls until mid-afternoon, and the dual backrest kept my spine aligned far better than my old single-panel chair. During a two-week stretch of heavy writing deadlines, I noticed less lower-back fatigue by day four. The mesh back breathed well even with Mesa heat pushing past 100 degrees outside, and the seat foam held its shape instead of flattening out. I wheeled it between my desk and a side table constantly, and the casters rolled smoothly on both carpet and tile. The tilt function made quick reclines easy during reading breaks. Durability-wise, the frame felt solid with no creaks after weeks of use. One honest note: the firm seat took some adjustment, but I grew to prefer it because it kept me from sinking into a slouch. For anyone building out a full ergonomic desk setup, this chair fits right in as a dependable centerpiece.
How It Compares to Alternatives
Compared with the Sihoo M57, the M59AS Dual trades the M57’s single-back design for a split dual backrest that hugs the spine more closely, which I found noticeably better for long sitting sessions. The M57 is still a solid pick and often costs a bit less, but the adaptive lumbar on the M59AS feels more responsive. Against a popular entry-level Herman Miller-style clone, the M59AS wins on adjustability and breathability at a fraction of the price. Build quality sits comfortably in the mid-range: not premium, but sturdy. If you’re weighing these two Sihoo models directly, my Sihoo M57 Vs M59as: I Bought Both—This One Gets My Vote breakdown goes deeper. Overall, the M59AS Dual delivers strong value for the money.
Who Should Buy This?
This chair suits remote workers, students, and office staff who sit six-plus hours a day and want real lumbar support without spending premium money. It’s especially good for people with lower-back sensitivity who need adaptive support. If you’re taller than about 6’2″ or prefer a plush, pillowy seat, consider a larger or softer option instead. Gamers who want deep recline and a footrest may also want to look elsewhere.
FAQs for sihoo m59as ergonomic office chair review
Is the Sihoo M59AS good for lower back pain?
Yes, in my testing the adaptive dual backrest gave steady lumbar support and reduced my lower-back fatigue over long days. It’s not a medical fix, but it encourages better posture.
How long does assembly take?
Mine took about 25 minutes with the included tools. The instructions were clear and all hardware lined up without issues.
Does the mesh back stay cool in hot weather?
Absolutely. The breathable mesh kept my back dry through hot Arizona afternoons, which was a big plus during summer.
What weight does the Sihoo M59AS support?
The chair is built for standard adult use with a sturdy nylon base. Check the Amazon listing for the exact weight rating before buying.
Can the armrests flip up?
Yes, the armrests flip up, which lets you tuck the chair under the desk and saves space in smaller rooms.
Is the seat cushion firm or soft?
It leans firm. That supports posture well, but if you love a soft pillow feel, give yourself a week to adjust.
Conclusion
After weeks of real use, the M59AS Dual earned a spot in my daily routine thanks to its adaptive lumbar support, cool mesh back, and sensible adjustability. It’s not perfect — the firm seat and high headrest take some getting used to — but for the price, it’s a smart buy for most home-office sitters. If you want dependable ergonomic support without overspending, this sihoo m59as ergonomic office chair review points to a solid yes.
