SIDIZ T50 Review: Is it Worth the Price?

Office jobs should not come at a price. Your comfort while sitting in your office chair matters, which is why ergonomic chairs are becoming more and more popular every day.

The SIDIZ T50 is a highly adjustable ergonomic office chair. SIDIZ is a Korean company that specializes in ergonomic office equipment.

SIDIZ TN50 Chair Series (Blue + Lumbar + Headrest)

We’ve studied and used the SIDIZ T50 in hopes of helping you find the ergonomic chair that will work best for you.

Though the SIDIZ T50 has already received multiple design awards and can be found throughout the world, we wanted to make sure the chair was up to our standards.

Read our review below for an in-depth look at how this chair holds up in comparison with other chairs on the market.

  • GIVE FREEDOM TO YOUR BODY : T50 is not only beautiful, but also practical in the ergonomic point of view. It ideally supports your back, helping you stay comfortable all day long. With T50 moving naturally with you, you‘ll be supported in every single position. ​Experience SIDIZ’s advanced ergonomic technology with T50. Key Product Features
  • ERGONOMIC S-CURVE DESIGN: The beautifully-shaped backrest makes your waist remain in an S-shape and prevents back pain while weight on the lumber disk is distributed properly.

If you have to sit at a desk every day, you know how uncomfortable it is to have a lack of back support in your chair.

The SIDIZ T50 was designed specifically for those of us that sit at our desks for long stretches of time on a daily basis. This chair was designed for comfort and efficiency in the workplace, which is why the price reflects a chair that you should be able to use for a long time.

The ergonomic nature of this chair is noticeable in the numerous positions the chair can be adjusted to fit. This chair feels comfortable to sit and work in for long periods of time because of the many features included within the chair’s structure.

Some of our favorite features about this chair include:

  • Multi-limited tilting function
  • Mesh backrests
  • Adjustable seat, armrest, and lumbar positions

Multi-Limited Tilting

SIDIZ T50 Highly Adjustable Ergonomic Office Chair (TNB500LDA): Advanced Mechanism for Customization/Extreme Comfort, Ventilated Mesh Back, Lumbar Support, 3D Arms, Seat Slide/Slope (Gray)

The multi-limited tilting function is the ergonomic feature that sets this chair apart from other office chairs. This feature allows you to set parameters for how far you want to be able to lean back in the chair.

As you lean back, the chair will follow your movements but will become sturdy and resist moving back too far, based on which of the five settings you have set on the chair.

This adjustable feature lets you lean back and relax in the chair without feeling like the backrest is bending back too far. You’ll always feel secure in this chair, no matter how far back you choose to lean during your breaks.

The tilting tension is more adjustable on this chair than many others that are around the same price. The difference between the tilting capabilities of this chair and others is how this chair guarantees to keep you seated in a healthy posture, no matter what settings you choose.

Sitting in a healthy posture that keeps your spine straight and lower back supported is what will make the difference for how you feel after work. If you stay in a healthy posture throughout the day, you will likely be less sore and uncomfortable from sitting for several hours straight.

Cooling Backrest

The gray, mesh material that makes up the backrest of this chair is a huge selling point for interested buyers.

Staying cool in your chair is important, and this mesh fabric guarantees you won’t get too warm throughout the day.

The polyester stripe mesh is aerated to provide an escape for moisture as you sit to do your work. Even though soft fabrics often trap odors, this mesh fabric is so lightweight that you’ll be able to use the chair for years without seeing any noticeable changes to the quality of the mesh.

Adjustable Seat, Armrest, and Lumbar Positions

On top of the tilting tension adjustments, this chair can also be adjusted in many other ways.

The seat of the chair itself can be moved forward or backward and the armrests can be moved into three different positions to guarantee you are able to fit comfortably.

The lumbar support can also be made tighter or looser, depending on your preference.

To adjust the chair, you can slide the seat forward or backward using levers hidden under the seat. You can move the armrests to your liking by gripping and pulling them to click into one of the three positions available.

Both the height and depth of your lumbar support can also be adjusted while using the chair. This level control is more than you’ll find on similarly priced chairs with a separate lumbar component, such as the Duramont office chair, which only allows for depth control.

This guarantees that you are able to find the appropriate support for you, no matter what size you are or what position you sit in.

An adjustable headrest is also available for an additional cost on most models of this chair.

What Could Be Better About this Chair?

SIDIZ TN50 Chair Series (Blue + Lumbar + Headrest)

As mentioned above, the price for the SIDIZ T50 is a bit steep. The ergonomic capabilities of the chair are what brings the price up, but we think there could be more added superficially to make the chair look as expensive as it is.

The chair is mostly plastic, with just aluminum at the base of the seat. The gray structure and backing of the chair is only broken up by the dark blue color of the seat.

Several owners of this chair have also remarked that it is ideal for someone who is not considered petite.

Petite individuals who are 5’6″ or shorter may be uncomfortable sitting in this chair because of the distance of the seat from the ground. Though the seat position can be adjusted, the size of the seat may still cause discomfort for the back of the legs for shorter individuals.

Aside from those two caveats, this chair is a great ergonomic choice for anyone looking for a new office chair.

The T50 is an excellent all-day task chair with options like the headrest and adjustable lumbar support to turn it into a full on ergonomic throne. On the other hand, for a bit more money, you can purchase the T80, which is the SIDIZ flagship model for German ergonomic design.

The T80 has the same ergonomic features available on the T50 – the multi-limiting backrest, 3D adjustable armrests, breathable mesh backrest, and sloping front seat edge – plus a few more bells and whistles you would expect at this higher price point.

For example, with the T80 you get a true synchro tilt mechanism, where the seat pan and backrest adjust independently to help you find the right ratio for better sitting posture.

Plus, it comes with an adjustable headrest and slightly larger seat width and backrest dimensions.

There are some design features that set the T80 apart as well. For example, the tension adjustment knob allows for a more specific tuning feel than the lever mechanism on the T50.

And you get different color options with the T80, including sleek and professional light or dark gray version, plus 2 Marvel edition options (Captain America or Iron Man) for the comic book fans out there. The Iron Man version actually comes with a PU leather seat for a real luxury gaming chair experience.

Is spending more for the T80 worth it?

If you plan on using your chair for gaming, need additional room or support, or just want a top-end ergonomic experience while sitting at your computer, you can’t go wrong with the T80. It’s up there with the likes of Herman Miller and Steelcase.

However, if you just need a very comfortable and ergonomic chair, with nice styling for your home office, the T50 will do the job just fine.

Which brings us to our conclusion.

Our Overall Thoughts on the SIDIZ T50

The SIDIZ T50 is a great example of a reimagined and comfortable chair. The ergonomic capabilities are sure to appease even the pickiest individuals because there is an adjustment for the chair to fit virtually any need.

This company even makes one of our favorite desk chairs for kids, so they know how to design for users with different ergonomic needs.

Though the price is high, the abilities of the chair are vast. The high-quality products used to make the mesh backing and adjustment levers are sure to last many years, making this product a worthwhile investment.

The lumbar support within the backrest, as well as the adjustable features for tilting and changing the armrest positions, make this chair a great option for anyone who must sit for many hours at a time.

Correcting any bad body positions and encouraging positive posture can make all the difference for your comfort, even when you aren’t sitting anymore.

Consider this chair in your venture to purchase new office material for the coming year – your back will thank you!
