The Sidiz T80 office chair is a high-end ergonomic chair made in South Korea. Broadly, it stands out with a futuristic design and advanced features.

Seeking an alternative to pricier Herman Miller or Steelcase chairs? This Sidiz T80 review explores its features and value proposition.
While top ergonomic chairs from Steelcase and Herman Miller often exceed $1,000, the Sidiz T80 offers a compelling alternative at $749.00.
However, these high-end options often come with 12-year warranties, compared to the T80’s 3-year warranty. This review dives into the value proposition of the Sidiz T80, considering its features, price, and warranty.
Sidiz T80 Gaming Office Chair Review
The Sidiz T80 is a high-end, full-featured ergonomic task chair. Chairs with comparable features include the Herman Miller Aeron ($1395+) and the Steelcase Gesture (Price not available).
The T80 is a few hundred dollars cheaper than both. However, it only has a 3-year warranty, well short of the 12-year protection offered by the other two. Those differences aside, the T80’s features compare well to both the Aeron and Gesture chairs.
Sidiz T80 Chair Features
The T80 has several impressive features. Here are some highlights:
Synchro-tilt and seat angle slope
The T80 has a seat that angles both up and down. With its synchronous-tilt (synchro-tilt) feature activated, the seat tilts up with a 1° range as the user reclines.
To support forward-learning work, you can manually tilt and lock the seat at a downward angle.
Adaptive mesh backrest and padded foam seat
The T80 chair comes with an adaptive mesh backrest and a padded fabric seat. The mesh back is designed to provide ultra-breathable support while adapting to your spine’s micro-movements.
The padded fabric seat contains a layer of memory foam plus a highly elastic sponge with a semi-firm feel. When you sit, there’s a slight give as it adapts to shape of your buttocks.
The fabric cover is not replaceable. To keep things hygienic, you should follow some fabric gaming chair cleaning best practices.
Notably, the seat cushion is replaceable. If yours wears out, you can contact Sidiz for a new one.

T80 Chair Sizing
The Sidiz T80 has a compact seat. But with flat edges, it provides plenty of room for the legs.
- Seat width x depth: 19.8″ (W) x 19.6″ (D)
- Backrest width x height: 19.8″ (W) x 29.7″ (H)
- Floor to seat range: 15.5-19.5″
- Size rating: people 5’5″ to 6’6″ tall; up to 250 pounds
On paper, these dimensions look similar to typical gaming chairs for small people. But Dr. Disrespect is 6’8″ tall. Thus, even with smaller contact points on the seat and backrest, the T80 should fit most adult sizes.
