Enjoy ultimate comfort with the medically endorsed NetOne® High-Back Office Chair.

With a unique pivot lumbar support system and contoured frame mirroring the S-shaped curve of your spine, the NetOne® ensures optimal lower back support  –  whether you are in forward-based keyboard posture, reading a document, or on a call.

  • Adjustable Seat, Armrest & Headrest
  • Extended Recline Position for Non-Keyboard Posture
  • Sustained Back Support
  • Mesh Back & Leatherette Seat
  • Delivered Fully Assembled 
  • 5-year Guarantee on Parts
  • 1-year Guarantee on upholstery 

Delivery is free anywhere in South Africa and every chair arrives fully assembled, so you unbox it and sit down. Every product comes with a 30-day money-back guarantee. If you're not happy, we'll refund you in full, less the relevant delivery costs.

The High Back carries you the whole way up, from the curve of your lower spine to the back of your head. A physiotherapist shaped the support so it meets your back where the day actually lands, and follows you from a keyboard lean into a full recline. The mesh keeps the air moving while the frame holds the line.

  • An inner and outer shell pivot with your lower back through a frame contoured to the S-curve of your spine, so the support tracks you from a forward keyboard posture into a full recline
  • The headrest adjusts to meet the back of your head, so the support that starts at your lumbar runs the whole length of your spine and gives your neck somewhere to rest between calls
  • The seat depth slides to your leg length and the front edge falls away in a waterfall, keeping the pressure off the back of your knees through the longest sit
  • Separate levers for height, backrest, seat depth and tension sit within reach from the seat, and the backrest locks at five points, so you set the posture once and forget the controls
  • The arms adjust through height, depth and angle.

Will it fit my frame?

The seat depth adjusts to your leg length and the gas lifts the seat through 44 to 54cm, so shorter and taller sitters both get their feet flat and their back against the support. It carries up to 140kg on a steel frame built to hold its shape under weight.

Mesh backs sag over time. Does this one?

The mesh sits over a machine-moulded frame reinforced to hold its tension, not a loose panel stretched across a hoop. Behind it, a pivot lumbar system moves with your lower back, so the support comes from the structure rather than the fabric.

Is it built for full days at a desk?

The synchro mechanism keeps the seat and back moving together as you shift, and the backrest locks at five points from upright keyboard work to a longer recline. The support follows the posture instead of fighting it, which is the part your lower back notices by mid-afternoon.

What does the chiropractic endorsement actually mean?

The NetOne carries the endorsement of the World Federation of Chiropractic, the body that represents chiropractic associations internationally. It points to a chair design judged by people who treat spines for a living, which is the same thinking a physiotherapist brought to it in the first place.

Why a headrest?

The back supports you to the top of the shoulder blades, the zone that carries you through keyboard and desk work. If you want neck and head support for longer reclining, that's where the high-back sits in the range.

Will the armrests clear my desk?

The arms adjust through height, depth and angle, with the height moving across an 18 to 26cm range above the seat, so you can drop them to slide under a desk or bring them up to take the load off your shoulders.

How long is it covered?

Five years on the chair and mechanism, one year on the upholstery. The steel parts are epoxy coated against wear, so the cover sits where the chair does its work, in the parts that move and carry the weight.

Will the headrest reach me if I'm tall?

The headrest adjusts to meet the back of your head rather than sitting at a fixed point, and the chair stands 100 to 112cm overall, so a taller sitter gets head support without stretching for it.The headrest  would not adjust high enough for users over about 6.2 ft. The seat lifts through 44 to 54cm to bring the rest of you to the right height.

Best office chair!

I am a legal practitioner and spend hours sitting in front of my pc and in court, I have a pinched nerve in my L5 and S1 which caused tremendous pain and a dropped left foot from my sciatica. This chair has alleviated the pain and made sure I am sitting in a correct position. Well worth the price and great service!

Nice chair

Nice chair, great back support and height adjustable arm rests.

My only complaint is that I wish the chair reclined more than just the back tilting backwards a little bit but otherwise its a fantastic chair! 9/10 do recommend.

Life-changing

I have quite a well-kitted-out home office. If I could go back, I would have prioritized getting this chair before other home office upgrades. Having a proper chair has really helped with my longevity and comfort. I feel more relaxed in my office. The staff from Ergotherapy were extremely friendly and helpful. They even let me try out different chairs at my house free of charge.

GetOne high back chair - long term user

After herniating a disc in my lower back in 2009 I was told to buy and Ergotherapy chair.

It was one of the best investments ever made. The Get One high back chair is still going strong. Currently my wife is using it and has just purchased her own GetOne Chair.

Thanks as well to the staff, particularly Cameron - great service.
Fabulous SA product and SA company thanks guys

I bought my original Ergotherapy chair back in 2005. Twenty years later, it's still in perfect condition. German engineering on South African soil. My back thanks you every day. Saving up to buy one for my hubby soon :-)

A great addition to my home office

I purchased this chair after it was recommended to assist with my lower back issues. I was impressed with the whole process from ordering, updates and getting the product. Being so used to having to assemble products at home, it was great to have a chair fully assembled with just some minor adjustments to get it ready for us. It is doing the trick in helping support my back.

Full spinal support at work

Due to accident injury to my back I was struggling to maintain lengthy sessions seated at my desk and screen. I would suffer from backache in the thoracic and lumbar areas. Since acquiring the Ergotherapy NetOne High-back office chair I have been working without pain. Brilliant!

Ergotherapy's products are value for money and lasts forever! Their service is excellent as well. Very happy with yet another great purchase from Ergotherapy.

Meirion Wyn Griffiths

The reason I bought my NetOne chair seven years ago was because of a lower back injury. As a professional writer spending eight to ten hours a day sitting in front of my desk, I cannot afford to compromise with cheap office furniture, and my NetOne has been my saviour. It's a top-quality product (that still looks brand new) that's matched by hugely efficient, friendly service. I highly recommend it.

The Throne Our Backs Deserved 👑

We decided it was time to invest in proper office chairs, and after much searching, we landed on the Net One High Back chairs from ErgoTherapy. Let’s just say… our backs and productivity levels are eternally grateful.

From start to finish, the service was outstanding. They under-promised and over-delivered, literally! We ordered two chairs, but only one was in stock. Instead of leaving us one seat short, they sent over a demo model so we wouldn’t have to suffer on an old, unsupportive chair while waiting for the second one. We didn’t even have to ask, they just made it happen.

Yes, it’s a big investment for an office chair, but 100% worth it. The comfort, support, and build quality are top-notch. If you spend long hours at a desk, do yourself (and your spine) a favour and check them out.

5 stars all the way! ⭐⭐⭐⭐⭐

Best investment for WFH

I've been using the Ergotherapy Netone High Back for more than 12 months now. It's the best investment I've made for my work-from-home productivity. I can just sit and sit for very long spells without worrying about posture. It seems very well made and nothing has broken since I've used it. And there's local customer support available if something does break. Very pleasant company to deal with.

Well worth it

I bought my Get one Ergonomic chair around 2011/2012. It is absolute worth spending a little more money than to buy the cheap ones, because ones health depends on it. In the long run you will spend much less than having to replace the cheap ones that does not last.

Net One chair

Ergotherapy is a very efficient company to work with. My online order was despatched within 5 days - I actually received it on the 5th day (Pretoria). The agents communicated with me throughout. The Chair is very comfortable and has reduced my pain levels. I use it at my desk, at the dining room table and wherever I need to sit with friends in the house. I just wish I could carry it with me! It has been money well spent.

Support from your lumbar to your head

Support from your lumbar to your head

The pivot lumbar system meets your lower back and the adjustable headrest meets the back of your skull, so the support runs the full length of your spine instead of stopping at your shoulders. The frame is contoured to the S-curve you were built with and holds it whether you're forward over a keyboard or eased back on a call. The longer you sit, the less you think about sitting.

Cool where you carry the heat

Cool where you carry the heat

A mesh back over a machine-moulded, reinforced frame lets the air move through where a padded back would trap it, so the support stays firm without the warmth that builds across a long afternoon. The frame holds the tension so the mesh doesn't have to, which is why it keeps its shape long after a stretched panel would give.

Set once, reached from where you sit

Set once, reached from where you sit

Every control has its own lever, gas height, backrest, seat depth and tension, and each one sits within reach without leaving the seat. The backrest locks at five points and the seat slides to your leg length, so the chair fits the way you work rather than asking you to work around it.

BUILT DIFFERENT. DOWN TO THE DETAILS

DESIGNED BY GARY

This chair exists because Gary spent years treating patients for the same complaint, lower back pain from sitting. The same muscles, the same posture, the same problem, all caused by chairs designed by furniture companies who had never studied a spine.
