Sitting in the same position for hours at a time can lead to a number of health problems, including back pain, neck pain, and blood clots. That’s why it’s important to find the best chair for sitting all day that is comfortable and supportive. For people who sit all day, an ergonomic chair is the best option. These chairs are designed to reduce strain on the spine and promote good posture. They also have adjustable features that allow you to customize the fit. In addition, ergonomic chairs often come with built-in lumbar support, which can help to prevent back pain. If you’re looking for a comfortable chair that will support your back and help you stay healthy, an ergonomic chair is the best option.
As a general rule, the right office chair will help you maintain a neutral posture, which means sitting with your feet flat against the floor. Your pelvis should be slightly elevated above your knees, with your ears, shoulders, and hips in alignment.
If you’re looking for the best chair for a sitting day, I believe I can help. For over 30 years, I’ve been practicing chiropractic, and during that time I’ve also trained as an ergonomist. I have a published book on the subject of sitting, spoke on this subject on national tv, and have engineered a number of solutions to help people achieve better posture and comfort while sitting. In addition, I ran a successful Kickstarter campaign to fund the development of my latest project, a set of ergonomic seat cushions. I am confident that I can offer some helpful insights about memory foam seat cushions based on my experience and expertise.

8 Office Chair Essentials for Sitting All Day
Adjustable Seat Height
The gas cylinder is often overlooked when purchasing an ergonomic office chair, but it is one of the most important components of your chair. If your gas cylinder is correctly installed, it can be adjusted to match your body type and height.
An adjustable footrest may be an option if you have inherited the chair and desk. If this is the case, however, I strongly suggest you consider a gas cylinder shock replacement. Gas cylinders are cheap and easy to replace.
The following technical jargon will help you make an informed decision regarding gas shock cylinders:

Length of gas shock cylinders:
- The capacity of the cylinders ranges from 10 to 25 cm, depending on the chair type.
- Most chairs come with a 13cm cylinder.
- Manufacturers offer a choice between a 10cm, 13cm, or 15cm cylinder in most cases.
How do you measure a gas cylinder for an office chair?
- Measure your height – Most manufacturers have a cylinder size that corresponds to your height.
- Measurement is the travel of the seat, which is also called ‘stroke’.
Different classes in ergonomic chair gas lift cylinders:
A wide range of ergonomic chair gas lift cylinders is available, from Class 2 to 4. Class 3 and Class 4 are the most popular and are commonly recommended for their increased longevity. Here are the guidelines:
- Class 3 gas cylinder is suggested for weights up to 150kg
- Class 4 gas cylinder is suggested for weights up to 205kg.
Are All Chair Shock Cylinders Universal?
- Always consider what height for your seat is.
- Also, ensure that your gas shock travel is smooth and noiseless.

Forward Seat Tilt
I believe that the best feature of any good office chair is the forward tilt. Some standards recommend up to 20° of forwarding tilt. A forward tilt allows you to adjust the chair’s seat angle at your discretion. By changing the seat tilt, the pressure on your back will be reduced.
Additionally, a healthy posture can also be easily achieved by sitting on a chair at the right angle. Besides, it helps you maintain a healthy posture while sitting. It can even improve blood circulation in your legs and feet.
I discovered that a forward seat tilt positions your pelvis in a more neutral position which helps take the load off your spine and disperses your weight into your core muscles. A forward seat tilt encourages an active posture all day long.
If you don’t have this feature on your chair, I would strongly suggest that you consider sitting on a seat wedge. Make sure that the thicker part of the wedge is towards the back of the chair. I wrote a ‘hands-on’ article explaining the unknown pros and cons of kneeling chairs HERE.
Ideal Seat Pan Depth
In my clinical experience, I have found that the seat pan depth is the second most comfortable adjustment that you can make on your ergonomic office chair, next to the forward tilt. This comfort is primarily due to increased surface area.
- Short seat depth can cause pressure points, which may lead to back pain.
- Seats that are too long may limit blood flow to your legs and feet.
On some chairs that offer it, you can adjust the seat pan forward and backwards about 130mm. Typically, this kind of adjustment is a one-time act, but in shared situations, it becomes essential.
How to set your seat pan depth:
- Make sure that your back is tight against your backrest.
- There should be two to three fingers’ distance between your knees and the edge of your seat.

Backrest Tilt Adjustment
A standard office chair tilts its back 10 degrees; most modern models easily exceed this recommendation. I like this feature because it enables movement throughout your day. Remember, the best posture is a moving posture. Your movement is your medicine!
Balance is the biggest issue here. There shouldn’t be a risk that the chair falls over backwards with this chair. It’s paramount to test this feature before purchasing an ergonomic office chair.
The reason is that we all are unique in our physical shape. If you are heavy in the top or taller, your weight will be higher in the chair, making it easier to lean too far backwards.
A word of caution is that if you are exceptionally tall or top-heavy, you should not be using a chair with a high degree of backwards tilt.
The backrest should have the lumbar support set at about the L3/L4 vertebrae, depending on the width of the seat. I’ve written a complete hands-on review about the Do You Really Need Lumbar Support? and here are some of the shocking issues that I ran into in this post!
- Lumbar support that is too high can adversely affect the spine’s natural curvature (lordosis).
- Lumbar support that is too low may cause back pain as it will cause too much pressure on the base of your spine.
The difference between people in the place of lumbar support in a seated posture is surprisingly minimal, therefore height adjustment is not critical. Despite this, the degree of resistance provided needs to be adjustable. The shape of the lumbar support can be altered with many designs on the market.
I was surprised how similar cheap memory foam seat cushions with FAKE REVIEWS were on Aliexpress from the listing on Amazon!
Synchronised Seat Mechanism
In biomechanical jargon, coupled or synchronised motion is the movement along one axis (translation or rotation), with another motion along a second axis.
In plain English, this mechanism enables the backrest to synchronise with the seat so that when you recline, the small of your back remains supported. Synchronised mechanisms combine both seat and back tilt into one function. If the seat is moved, the backrest also moves, usually in a ratio of 2 to 1.
I have found that most people have little or no knowledge of how to adjust their chairs (apart from the gas lift), and however many knobs and adjustments are on a chair, the less likely users are to be able to set the chair up correctly. A proper seat mechanism takes the guesswork out of the equation.
With adjustable armrests, the user balances stability by getting close to the desk. If you don’t get your armrest right, odds are that you may develop neck and shoulder pain over time.
The 4D armrests are the most comfortable and flexible in terms of height, width, and pivot. 4D Armrests are adjustable in 4 dimensions:
- The armrest can be adjusted by height (up to 10cm)
- Forwards or backwards
- Left or right
- Sideway angle
Always look for 4D armrests that can lock the desired position.
Backrest Height Adjustment
A backrest without the ability to adjust the lumbar position is rarely desirable for the end user. However, a study reveals that a backrest needs to be easy to adjust or people won’t change it.
You will want a seat that enables users to adjust the backrest by lifting it and clicking the mechanism in place. Adjustments are typically not necessary after the chair is first set up for a specific person.
By adjusting the tension knob or wheel, the chair acts as a cushion for pushback against tilt. Therefore, you are more comfortable and in complete control of the chair. You can adjust the resistance to your body weight and move freely and comfortably all day.
Ideal Seat Material
That soft foam or mesh feeling can indicate sloppy mesh fitting or an excessively low density of the foam. The foam density or mesh fitting needs to allow a certain degree of conformity, but you may develop back pain over time if it is too soft or firm. To help chairs maintain their shape and resilience, a certain density and thickness of foam are required.
- Since the seat typically bears the maximum load, the density of foam on the seat usually surpasses the density of foam on the backrest.
- A seat profile with a thinner body needs a higher density of the foam.
- Office chairs with two foams, softer on top and firm underneath, are practical.
Office Chair Castors
A soft-tyred castor is usually suitable for use both on hard floors and most office carpets. However, with the advent of more home workers, a hard-tyred castor is designed only for use on thicker carpets.
Castors allow you to roll your office chair around and extend your reach easily and quickly. However, you must keep a few things in mind:
- A soft-tyred castor is generally the better choice if you are uncertain about which type to buy.
- Another option would be a brake castor, which keeps the chair from moving when you stand. The chair stays in place when you take your weight off it, and the friction brake keeps it from going too far.
Best Ergonomic Seat Cushion for Sitting All Day
The human body was not designed to sit for hours at a time and sitting for extended periods can have a range of adverse effects on the human body. Poor posture as a result of slouching can lead to neck and shoulder pain, but this is not something that has to be endured. Ergonomic seat wedges are a simple way to maintain good posture and alignment while sitting, which reduce discomfort and can even help promote core strength and balance. Because seat wedges keep the user in an upright position, it’s also possible to reduce tension in other areas of the body. If you spend hours at a time seated, it may be worth considering incorporating a seat wedge into your daily habits for improved comfort and better health results.
Ergonomic Lumbar Support Cushion
Are you looking for an easy way to strengthen your core without leaving your chair? With ergonomic lumbar support, you can provide yourself with the necessary relief and support that sitting for extended periods of time can put on your body. With natural latex material and comfort-focused straps, you can sit confidently knowing that your back is in good shape. So why not get started today? Make a conscious effort to build strength in your core through the use of proper seating posture and with help from the ergonomic lumbar support, soon your core will be stronger than ever. Investing in yourself doesn’t have to be a hassle – choose ergonomics, and you’re already one step closer to a stronger core!
A good office chair will help you maintain a neutral posture, which is essential for keeping your spine healthy. By following the guidelines we’ve outlined in this post, you can find an office chair that will keep you comfortable and pain-free all day long. Have you found the perfect office chair yet?
