Compared to the Herman Miller Aeron, the Sidiz T80 has similar features but costs around 40% less. Made in South Korea, the T80 is geared towards esports pros and power users. Recently, Sidiz expanded this product line to include two official Marvel superhero editions. This Sidiz T80 review covers the specs and designs of all three chairs in the 2021 T80 collection.
One of the problems with high-end ergonomic chairs is the price. Top models from Steelcase and Herman Miller both cost well over $1000.
Another problem for gamers is the drab, corporate styling. The Sidiz T80 solves both of those issues with a reasonable price and three unique designs.
Headquartered in Pyeongtaek, South Korea, Sidiz has been designing office furniture since 2021. The T80 launched in east Asian markets in 2014. Since then, it has won several design awards in South Korea and Japan. In 2018, Korean esports team Gen G signed a deal to use the T80 as their official team chair.
Soon after, Sidiz quietly began selling the T80 in western markets. In early 2019, famous streamer Dr Disrespect caused a buzz after he started using one. In this video, he raves about the chair:
In 2020, Sidiz began a strong marketing push for the T80 in American markets. The company now sells its products on Amazon.
Detailed Sidiz T80 review
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 Leap 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
On its South Korean website, Sidiz sells several variants of the T80. On Amazon, all models come with adaptive mesh backrests and fabric seats with foam padding.
The mesh back provides ultimate breathability and comfort. When you sit, the mesh has an elastic quality that gives enough to take the shape of your body. The advanced breathability keeps the seat cool, even after long periods of sitting.
The seat cushion is replaceable. If yours wears out, you can contact Sidiz for a new one. It contains a layer of memory foam plus a highly elastic sponge.
Over the top is a breathable fabric cover. The whole unit provides firm resistance and cool comfort over long gaming or working sessions.
Summary of features
Like other high-end task chairs, the T80 comes packed with impressive features.
- Synchro-tilt: seat pan angle 1°; backrest 90° to 114°.
- Spinal curve support: height adjustable lumbar; height and depth-adjustable padded headrest.
- 3D armrests: adjust the arms in three directions. The range provides robust support for the shoulders and wrists.
- Seat slide plus slope: slide the seat forward or back; manually slope down by -1°.
- Premium Padding: resilient memory foam with a layer of antibacterial elastic sponge. This provides firm, dense, very comfortable support.
- Warranty: three years, plus 30-day money-back-guarantee (details)
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.

T80 chair designs
There are four models in the 2021 Sidiz T80 collection. How to choose the best design for your needs? Colors in an environment influence both mood and behavior.
Using color theory, we can divide different shades into a color spectrum to gauge the effects.
- Warm colors: reflect more light, sending more information to the brain. Red is a high-wavelength color that is intense, active, and passion-inspiring.
- Neutral colors: are achromatic (off the color spectrum). Black, grey, and white slow the heart rate and promote feelings of formal harmony.
- Cool colors: foster a sense of calm, creative introspection. Blue is a low-wavelength color that recalls nature. It has a calming, serene effect. Studies show that it’s also the best color for fostering creative thinking.
This UBC study found that red and blue are the two shades that best improve brain performance. Red boosts performance on detail-oriented tasks like proofreading.
In comparison, for creative tasks like brainstorming, blue works better. In blue vs red environments, blue ones produced twice as many creative outputs as red ones.
Sidiz T80 classic edition
Amazon price: $691.89
There are two standard designs in the T80 collection. The T800HLDA Dark has a grey fabric seat and black components. The TN800HLDA Light uses a lighter shade of grey plus white components.
In color psychology, grey is the only color without psychological properties. In contrast, black conveys power, coldness, intimidation, and control.
If that’s too much for you, the white model is a softer option. Its white base adds contrast to the grey fabric. As well, many interior designers use the brightness of white to create a sense of space or add highlights to other colors.
The T80 TN800HLDA light edition is also available on Amazon for $691.89.
T80 Captain America edition
Amazon price: $799.00
The Captain America chair has a blue mesh backrest and PU leather padded seat. Complementing those parts are white armrest and backrest components and an aluminum base.
Captain America’s mask appears on the headrest. His Vibranium shield is on the lumbar support and also woven into the mesh backrest.
T80 Iron man edition
Amazon price: $799.00
The Iron Man chair stands out with a dark red base, golden components, and a red chair base. If you can handle warm colors, this model is striking and intense.
Iron Man’s mask appears on the headrest. His Arc Reactor is on the rear lumbar support and also in the red mesh backrest.
Who should buy a Sidiz T80?
Because of the cost, high-end ergonomic task chairs are often considered CEO chairs. These are pricey power seats that convey status.
But the Sidiz T80 is marketed at esports players. That makes the T80 an alternative to pro esports PC gaming chairs. For those willing to pay more than they would for a PC chair, there are a few benefits.
The Sidiz T80 provides comparable features to the Herman Miller Embody (around $1500). Head-to-head, the Embody offers precise micro-adjustments in the backrest, but no neck support. The T80’s backrest is less precise but comes with adjustable neck support. All other features are similar — but the T80 is half the price.
As Dr. Disrespect and team Gen G showed the world, the T80 works great as a gaming chair. Those who spend long hours sitting while doing complex work can gain an edge with these chairs. They support good posture, which boosts vitality and improves work performance.
