The SIHOO M57 is the most capable ergonomic chair available under $250. It has more adjustability than chairs costing twice as much, a reinforced aluminum base. If you want a serious step up from budget chairs without spending on a Steelcase or Herman Miller, this is where most people land.

Check Price on AmazonWhy the M57 Stands Out at This Price
Chairs under $250 usually make you pick one or two things: good lumbar or good arms. A decent headrest or a sturdy base. The SIHOO M57 does not make you choose. The lumbar adjusts in both height and depth so you can fine-tune exactly how much support your lower back gets. The 3D armrests move in three directions. The headrest tilts and lifts. The base is reinforced aluminum, not the nylon you find on most chairs at this price.
The full mesh design is the other thing worth noting. Most chairs in this range use foam seats and mesh backrests. The M57 uses mesh on both, which means air circulates below you as well as behind you. After three or four hours in a foam-seat chair, you feel it. In the M57, you do not.
It has passed over 100,000 safety tests and carries both BIFMA and SGS certification. It is also recommended by the Ergonomics Application Association, which is not something that shows up on many chairs at any price.

- Reinforced aluminum base, not nylon

Who Should Get This Chair
The M57 is the right choice if you are sitting four to six hours a day and the chairs under $150 are not cutting it. The jump from a FelixKing or Ticova to the M57 is noticeable — the aluminum base feels more solid, the mesh seat stays cooler, and the dual-direction lumbar gives you actual control over your back support rather than just up-and-down positioning.
If you work eight or more hours daily and want a chair that will still feel the same in five years, a refurbished Steelcase Amia or Steelcase Leap V2 is a more durable long-term investment. But for most home office setups where you are not logging eight-hour days every single day, the M57 is genuinely hard to beat at this price.
For shorter users, the 21.66-inch seat height may be slightly high. Our guide to office chairs for short people covers options with lower minimum seat heights.
7,980 reviews at 4.4 stars puts the M57 in a different league from most chairs under $250. The dual-direction lumbar, full mesh design, and aluminum base are features you usually pay more for. If your budget stops before a refurbished Steelcase but you want more than a basic budget chair delivers, this is the chair most people end up recommending to each other.
Frequently Asked Questions
Is the SIHOO M57 worth the price?
Yes, for users sitting four to six hours daily who want more than a basic budget chair without spending $400 or more. The dual-direction lumbar, full mesh seat, and aluminum base are genuinely hard to find at this price point.
Is the SIHOO M57 good for back pain?
The lumbar that adjusts in both height and depth means you can position support at the exact vertebral level where your lower back needs it. For general desk-related lower back pain, this is meaningfully more effective than a fixed or single-direction lumbar. For coccyx-specific pain, our guide to chairs for tailbone pain covers what seat features matter most for that issue.
How does the M57 compare to the SIHOO Doro C300?
The Doro C300 is SIHOO’s newer, more advanced model with dynamic lumbar that adjusts automatically as you move, ultra-soft 3D armrests, and independent backrest angle adjustment. The M57 has manual dual-direction lumbar. If you move around a lot during the day and want lumbar support that follows you without manual adjusting, the C300 is worth the step up. Full comparison is in our SIHOO chairs review.
What is the SIHOO M57 seat height?
The seat height is 21.66 inches. This works well for users from about 5 feet 4 inches upward. Shorter users may need a footrest. Seat depth is 18.11 inches, which fits average leg lengths without the front edge pressing on the backs of the knees.
