About SIHOO
SIHOO is an ergonomic chair manufacturer that sells widely through Amazon and its own online stores. It is best known for budget mesh chairs with headrests and adjustable lumbar support, and its Doro range brings more modern designs and features at higher prices. SIHOO chairs offer a lot of features for the money, though they do not carry the long warranties or proven decades-long track records of premium brands like Steelcase and Herman Miller.
1. SIHOO Doro S300: Most Adjustable SIHOO
SIHOO Doro S300
- Seat: Mesh seat and back
- Arms: 6D
- Lumbar: Dual dynamic lumbar with tension dial
The S300 is SIHOO's most ambitious chair, with dual dynamic lumbar wings you can tension with a dial, 6D arms, seat depth adjustment and a smooth weight-sensitive recline with a three-position limiter. Reviewers praise its solid, rattle-free build. It is heavy and has no separate headrest. Read our Doro S300 review.
- Choose it if: you want lots of adjustment and tunable lumbar on a mid-range budget.
- Skip it if: you want an adjustable headrest.
2. SIHOO Doro C300: Best Budget All-Rounder
SIHOO Doro C300
- Seat: Mesh
- Arms: 3D
- Lumbar: Self-adjusting (moves with recline)
The C300's spring-mounted lumbar moves with your back, and it adds a fully adjustable headrest, 3D arms, a breathable mesh seat and back and a recline that locks in several positions. It is rated for 300 pounds. Read our Doro C300 review.
- Choose it if: you want a headrest and moving lumbar for a low price.
- Skip it if: you want arms that lock firmly in place.
3. SIHOO M18: Best Lowest-Price Pick
SIHOO M18
- Seat: Foam with mesh back
- Arms: 2D
- Lumbar: Adjustable
The M18 is SIHOO's classic budget chair, with an adjustable headrest, adjustable lumbar, a breathable mesh back and a foam seat. It is simpler than the Doro chairs but remains one of the most affordable ergonomic chairs with a headrest. Read our M18 review.

When to Choose a Premium Chair Instead
SIHOO chairs are excellent value, but they are not the right choice for everyone. Consider stepping up if:
- You sit eight or more hours a day: premium chairs are engineered and warrantied for years of heavy use.
- You want a long warranty: Steelcase and Herman Miller offer about 12 years.
- You are a larger person: many premium chairs are rated for 400 pounds or more.
The Steelcase Series 1 is the most affordable step up. For our overall favorite, see the Herman Miller Aeron, and read are expensive office chairs worth it?

Buying Tips for SIHOO Chairs
- Check the exact model: SIHOO sells several similar chairs with different features.
- Check warranty terms on the listing: coverage can differ between sellers.
- Assembly: heavier models like the S300 are easier to assemble with two people.
- Mesh or foam seat: mesh breathes better; foam feels softer.
SIHOO Chairs by Body Type

| Shorter | M18 or S300 | The C300's seat height range suits taller users better |

What to Expect From a Budget Chair
Budget chairs like SIHOO's deliver features that once cost far more, including headrests, adjustable lumbar and multi-directional arms. The trade-offs are usually in materials, long-term durability, warranty length and how firmly adjustments lock. For part-time or everyday use, that trade-off is often worth it. For eight-plus-hour days, it may pay to stretch your budget. Read our guide to how to choose an office chair.
