Breaking it Down

We reviewed these chairs using various criteria. The requirements are rooted in many ergonomic prerequisites most people expect to have in an office chair.

Lumbar Support

A primary requirement people expect in an ergonomic chair is lumbar support. The office chair should support the neutral position of the spine to reduce pains and aches as one works.

The NOUHAUS Ergo3D features a dynamic three-dimensional lumbar support system. What it does, aside from just supporting the user’s back, is it hugs and adjusts to the contours of a person’s back and spine.

This gives you a significant improvement when it comes to back support. This feature helps reduce pain related to the compression of the spine.

The lumbar support with the SIDIZ T50 is stellar and can be adjusted according to your height and preferred depth. It is made of a comfortable yet sturdy mesh that allows for good ventilation, especially if you use a fan or AC as you work.

Like an invisible push, the chair’s back will make you assume an upright position as you sit. This might be your ideal chair if you need help with your posture.

Winner: While the Ergo3D can move to wherever the user wants it to, the T50 adds an extra feature to allow the user to sit upright. The winner in this round is the T50 because of its adjustable element that allows anyone to use the chair, whether they are short or tall.


An office chair’s headrest is a modern addition to the current office chair. What it does is support the person’s head while seated.

The headrest available in the NOUHAUS Ergo3D is a 2D 13 by 6.7-inch headrest. It is highly adjustable to support your head and neck, whatever your height may be.

This is an added bonus since most office chairs are usually equipped with a fixed headrest.

The T50 features a curved leather headrest attached separately on the backrest. This means you can take it off if you prefer. Another plus is the headrest is highly adjustable.

Winner: In this round, the winner is the T50 because it has an adjustable headrest. The only thing that makes us hesitate with the Ergo3D is its upholstered leather, which can be uncomfortable when the weather gets hot.

Back Rest and Recline Feature

The recline feature helps with pain reduction in the sitter’s back and neck caused by poor position or hunching at a desk as they work. If you suffer from acute back pain, make sure this requirement is high on your list.

The first chair is unique in the way that it features the Super-Lounge Tilt, which is a NOUHAUS signature. This office chair aspect allows the person using the chair to settle back and tilt the chair to 135 degrees.

There is also a lock feature that will allow you to retain the tilt for safety.

The T50 allows for tilting up to 25 degrees in five fixed positions controlled by a lever on one side of the chair. Remain upright to help keep you productive, or tilt to relax and lounge if video games are the agenda for the day.

Winner: There is no competition here. The Ergo3D takes the cake in the long run with its ability to tilt up to 135 degrees. Adjusting the tilt of the T50 will require pushing a lever when the Ergo3D can do the work by simply reclining it manually.


An armrest is vital because it takes some weight out of a person’s upper limbs and back. With armrests, there is less compression in the lower back. This is great especially if you suffer from lower back pain, which is usually a by-product of not having an ergonomic office chair.


You’ll be so comfortable in our Ergo3D Ergonomic Office Chair that you won’t even mind working.⁣

Another innovative feature of the NOUHAUS Ergo3D office chair is its 4D adjustable armrests. With this feature, a tall or petite person can adjust the armrests to their preference.

It gives maximum support and flexibility to the user, whether they slide it front to back, lift it up and down, or pivot the armrests at various angles.


Introducing : chairable T50

The T50 armrests can be adjusted in three ways: back and forth, up and down, and left to right. However, there is no adjustment for the whole arm width of the office chair. This aspect will be a problem if you are a heavier person who requires more armrest space.

Winner: The Ergo3D takes the cake in this category with its four-dimensional adjustment armrests.


The seat requirement of an ergonomic office chair is essential. It supports the bottom of your spine and compensates for your weight, preventing it from dropping down to your  waist as you sit. Look for a deeper seat if you are taller and opt for a shallower seat if you are shorter.


Review Nouhaus Ergo3D Office Chair 2022

The NOUHAUS Ergo3D seat has a dimension of 19.7 inches by 16.3 inches. Like the back material of this office chair, the seat is made of mesh for adequate airflow to prevent both sweating and feeling sticky when sitting for prolonged periods.


Sidiz T50 USER GUIDE by Fursys

The T50 office chair allows for the cushioned seat to tilt by controlling a lever on the side of the chair. Tilt your seat upward or downward.

Changing the seat angle will give you more hip room. It will also allow you to control the weight compressed.

Winner: The champion of this round is the T50 because of its ability to adjust according to the user. If you want a more leveled seat, this is the chair for you. The adjustable element is just the cherry on top.


Price matters, especially for consumers who have set a budget for an office chair. There is a common price range for an ergonomic office chair, but this does not mean a lower-priced chair below that range is not worth your money.

The Ergo 3D garnered a couple of points with its highly-adjustable four-dimensional armrests and 135 degrees tilting ability of the office chair’s backrest.
