The Raynor Ergohuman Chair Review - Stay Well-Adjusted In The Office

Buying yourself an ergonomic chair is a great idea if you want to get rid of back pain while sitting. Here's my review of one of the market leaders, the Raynor Ergohuman Chair

Sitting down for a few hours or more each day can be a major cause of back pain. 

Especially if you're doing it in a 'one size fits all' generic office chair. ​

Because not only do these chairs offer zero lumbar support. 

They also force you to sit with an unhealthy posture that piles pressure onto your lower back, neck and shoulders throughout the day.​ 

Seriously bad news. ​

So is it any surprise when your back starts complaining after a long day at the office?​ 

Now there are a few things you can do to minimise any back pain while sitting.

Such as getting your sitting posture right, keeping your core muscles strong, and taking regular microbreaks to get up, stretch and mobilise your body. ​

And another important thing to do is to get yourself a high quality ergonomic desk chair. ​

Because these chairs have great lumbar support and can be adjusted to fit your​ body perfectly. 

Which relieves the pressure on your lower back and makes sitting with a healthy posture so much easier.

And one of the best of the bunch for your back is the Raynor Ergohuman chair.

Read on to find out why.​

The Ergonomics

The reason that ergonomic chairs are such a good purchase for people with back pain is that unlike regular desk chairs they can adjusted to fit each individual perfectly.

Which helps you to maintain a healthy sitting posture and take the pressure off your back, neck and shoulders as you sit.

And the Ergohuman chair excels in this department.​

As it's fully adjustable and very easy to do with just one lever under the chair controlling everything.​

So here is the full list of what you can adjust.

​Seat Height

To maintain a good sitting posture you need to do two things.

Firstly you need to adjust the height of your seat to suit the height of your desk or workstation.

And secondly you need to be sitting at a height where your feet can rest comfortably on the floor while your knees and hips maintain a 90 degree angle. ​

And being able to adjust the seat height of the Ergohuman chair makes this easy to achieve.​

Simply use the lever under the seat to activate the pneumatic lift cyclinder and you can adjust the height from anywhere between 18.5" to 22.2" from the floor.​

​Seat Depth

Another great feature of the Ergohuman chair is that you can adjust the seat depth (how far away from the back of the chair it is).

So by sliding the seat backwards or forwards you can position your body at the right distance to maintain a good posture and utilise the chair's lumbar support to it's fullest.

​Back of the Chair and Lumbar Support

The built-in lumbar support that comes with the Ergohuman is attached to the back of the chair.

And together you can adjust the height of this up or down into a choice of 4 positions.

This allows you to position the lumbar support exactly where you need it.​


The headrest that comes with this model is a great way of supporting your neck as you sit.

But to do this you need to have it positioned in exactly the right place and fortunately with the Ergohuman chair you can.

You can adjust the height of the headrest by about 4" by moving it up and down.

And you can also rotate the angle of it to make it more comfortable for you.​

However the one option missing is that you can't move it forward so it may be too far back to get support from unless you are reclining.​

3D Adjustable Armrests

Having adjustable armrests on a chair is really important as it takes away a lot of the pressure and strain on your neck and shoulders.

And the 3D armrests on this chair allow you to do just that.

Not only can you adjust the height of them by moving them up and down.

You can also slide them forward and back and pivot them in and out to get them into the exact position you need ​them to be.

Tilt Mechanism

The tilt mechanism in this chair is a great way of relieving pressure and keeping your core muscles engaged while you sit.

As it allows you to either recline back in the chair or rock backwards and forwards, although it can't be tilted forwards.

And if you prefer to sit in a reclined position there are 3 lock positions that will hold the chair in place.

Also you can adjust the tension of the tilt making it harder or easier to recline back depending on your preference.​

Why Is It Good For Your Back?

If your office chair looks like this one then your back is in trouble. Upgrade it!

So as you can see the Ergohuman chair is packed to the brim with adjustable features that allow you to fit into it perfectly.

But how exactly does this help to keep your back healthier and out of pain while you sit?​

It's all about relieving the pressure on your lower back and keeping your muscles active.​

Relieving the Pressure and the Strain of Sitting​

Firstly this chair extremely well designed for people with bad backs and provides you with great lumbar support throughout the day.​

This is through the built in lumbar cushion that can be adjusted in height so it fits snugly right into your lower back.

Which is great as it helps you to maintain a healthy and natural 'S' curve in your spine as you sit rather than a 'C' curve that you get when slouching.

And this will be a big help in reducing the strain and pressure on your lower back while sitting.

Another element of the Ergohuman chair that makes it easy to sit with a healthy posture is being able to adjust the seat height and depth.

This means you can sit at exactly the right height for your desk and keep your workstation ergonomics optimal.​

And you can also sit at a height that allows you to rest both feet comfortably on the floor where they can also help to relieve pressure and support your body.​

While being able to move the seat forwards or backwards will position you perfectly with the back of the chair to help you maintain your posture.

The height adjustable armrests will ​also help to relieve pressure on your neck, shoulders and upper back by supporting your arms and keeping them at the right angle for working.

While the 5-point aluminium castor base will help to support you and keep your body stable and balanced as you sit.

So the Ergohuman really does do a great job of taking the strain out of sitting for your back.​

Keeping Your Core Muscles Active

One of the main reasons you develop back pain from prolonged periods of sitting is the inactivity this causes within your body.

Especially for your core muscles and the muscles that support your back.

Because as these muscles remain inactive as you sit in traditional chairs they weaken.

And over time this leads to your back getting less support and experiencing more pain as a result.

This is where the tilt mechanism on the Ergohuman chair is so great for your back.

Because it allows you to tilt and rock back and forth during the day as you sit.

And these small but consistent movements mean your core and trunk muscles remain active and don't weaken.

So your back doesn't lose it's support.

You can also adjust the tension of the tilt to make it harder or easier to tilt back.

In this way you can set the chair to go as hard or easy on your core muscles as you like.

And the recline function of the chair is great too as it allows you to take a rest from sitting in an upright position.

Which is a great way to relieve any tension that has built up.​

So I'd say the Ergohuman chair does a fantastic job both of relieving pressure and keeping your core muscles active.

And so it's a great chair for improving the health of your back and reducing back pain.​

How Comfortable Is It To Sit In?

Now I should probably start by saying that everyone has a different definition of what a comfortable chair is.

And if you like your chairs to be cushioned, soft and snuggly then you are going to be disappointed here.

Because the Ergohuman is designed to provide you with strong support to relieve pressure on your body rather than as a lounge chair to take a nap on.

​As such it uses a firm mesh material in the back of the chair and the seat.

And this may take some getting used to if you are used to sitting on softer chairs.

But the good thing about this mesh is that it is breathable as it allows air to flow through it.

So it will keep you cool and comfortable throughout the day rather than feeling hot and sweaty like sitting in leather chairs can.

And if you do like the firmer feel of sitting in this chair then it can be very comfortable for a couple of reasons.

​Firstly the ergonomic design encourages you to sit with a healthy posture that relieves the pressure on your body as you sit.

And secondly the tilt mechanism allows you to rock back and forth while you sit which prevents muscle tension from building up.

So your body will be less tense and in less pain during the day.​

​It also allows you to recline if you need to take a break and sit in a position other than the upright one.

Which is another great way of releasing stress and pressure.​

So while comfort isn't the primary selling point of the Ergohuman chair it still remains a very comfortable chair to sit in once you get used to the firm mesh.​

And if sitting on firm mesh really isn't going to work for you there are different versions of this chair available that come with the option of leather ​padded seating and/or back of the chair.

You will lose the breathability and coolness of the mesh by taking up these options.

But if you'll be more comfortable sitting on leather rather than mesh then this may be a price worth paying.

Different Versions Of The Ergohuman Chair

All 6 varieties of the Ergohuman chair.

In total there are 6 different versions of this Ergohuman chair.

There is the chair that is made from all mesh which is what I've been reviewing here.

Then there is the same mesh chair but with a leather padded seat.

And finally there is the same chair but made with leather rather than mesh.

Each of these come either with or without a headrest.

However all of the other features remain exactly the same so you can choose the one that suits your preferences the best.​

>> The Back On Site Verdict <<

So does the Raynor Ergohuman chair pass the test of being able to keep your back healthier and happier while sitting?

For me it's a resounding yes.

​As it has so many adjustable features that all work together to encourage your body into a healthy posture while you sit.

Which helps to relieve the pressure on your lower back and prevent the build up of muscle tension.

And by keeping your core muscles active with the tilt mechanism this chair will stop them from weakening and keep your back strongly supported.​

All in all it's a great chair for people that want to take care of their backs and reduce any pain from sitting.

And while it's not built primarily for comfort (and some may find it too firm to sit on) it's still a really comfortable chair in my opinion.​

So if you are looking to take the leap and invest in an ergonomic chair for your home or office then I'd highly recommend the Ergohuman chair.

​It might seem like a big purchase at first but when you weigh up the years of good service it will give you it becomes a bargain.
