The Sidiz T50 office chair confused me at first sight. On one hand, its sleek ergonomic design looks like something with a $1,500 price tag. It’s among the most attractive office chairs I’ve seen on the Australian market.

But on Amazon, it retails for about $540.

In a world dominated by cheap, disposable office chairs on one side and ridiculously expensive luxury exotics on the other, is the Sidiz T50 the perfect balance of both?

In my quest to find Australia’s best office chair, I bought one and used it in my office for a couple of weeks.

The results were surprising, but not in the way I expected.

Reasons To Buy The Sidiz T50 Office Chair.

The Sidiz T50 looks great. Easily one of Australia’s most visually appealing chairs, its design divorces that boring cubicle office chair aesthetic and embraces a sculpted, modern, minimalist look.

If you don’t love the typical chunkiness of ergonomic chairs, you’ll love the T50.

From a distance, the T50 looks like a premium chair that could compete with the likes of Steelcase and Herman Miller.

(Unfortunately, you realise that the build quality is much less impressive as soon as you touch it. More about this shortly).

T50’s synchro-tilt recline mechanism – something I’d expect in a $600 office chair – provides a smooth recline motion that doesn’t lift your legs.

Also typical for this price point is a very comprehensive range of adjustments. You get:

  • Seat height.
  • Adjustable seat depth.
  • 3D armrests that adjust for height, pivot and depth.
  • Headrest height and pivot.
  • Lumbar support with reach and height adjustment to encourage a healthy sitting posture.
  • Breathable mesh backrest that reclines into 5 lockable positions and tension adjustment.

I was surprised by the T50’s forward-tilting feature, which I haven’t seen since owning an Aeron. Activated by a lever, it tilts the chair’s seat pan forward by about 3 cm, creating a forward seat slope.

Above: Pull the lever on the left side of the chair, and the seat base will tilt forward.

This is very niche, and will appeal to two types of people:

  • Professionals who need to sit very upright and forward for short periods of time (e.g., doctors and optometrists examining a patient).
  • Back pain sufferers. The forward tilt can help them find an optimal sitting position that doesn’t upset the spine.


I wish the seat pan tilt adjustment lever was lockable. It sometimes activates autonomously when you shift your weight far forward or backwards.

T50’s bi-directionally adjustable lumbar support is one of the nicest-feeling I’ve experienced. It’s not at all pokey because it applies pressure across a wide area of your back.

In fact, the entire backrest feels great.

It’s large enough to cover even the largest backs, and flexes slightly – just enough to let your spine move while providing plenty of support.

The depth-adjustable foam seat pan is medium in firmness and will keep you feeling comfortable during long work stints. It doesn’t bottom out and yet provides plenty of cushioning and a waterfall seat edge to keep your backside cosy.

Meanwhile, the seat width is on point. While it’s wide enough for larger bodies, it doesn’t feel like the chair is about to swallow you

Smaller people will be able to sit cross-legged.

The removable fabric cover on the seat pan is a nice touch. Attached with velcro, it allows you to keep your office chair looking new by throwing it in a washing machine once every few months. Brilliant.

Sizing of the Sidiz T50 is ideal for shorter to medium-sized people.

Because the seat pan height goes quite low, down to 33.6 cm, people who are under 160 cm won’t find their feed dangling.

Unfortunately, this means the maximum height tops out quite early too – and people who are taller than 175 cm will feel that the chair is too small for them (and should get the ErgoTune Supreme instead).


The assembly is a piece of cake – despite the instructions being very fiddly and written in the smallest font I’ve ever seen in an office chair manual.

The Allen wrench included with the chair is an interesting hint at the Sidiz T50’s target market.

It’s very substantial, with a long handle that allows you to apply a lot of torque to the screws with minimal effort. Clearly aimed at petite people who may not have a lot of hand strength.

Reasons To Avoid The Sidiz T50 Office Chair.

Sidiz T50’s build quality is not great. In fact, for a $600 office chair, it’s terrible.

The armrests, headrest and seat pan fabric feel particularly cheap to the touch while the knobs and levers feel flimsy and unsubstantial.

Instead of hearing and feeling satisfyingly clicking sounds, you get notchy, rough movements.

The Sidiz is not nice to interact with.

The minimalist frame doesn’t have enough strength to cope with larger bodies.

Smaller people will be OK, but if you weigh more than 90 kg, you’ll feel capable of breaking the chair (even though it’s rated to 130 kg).

Depending on whether you buy the Sidiz T50 via Amazon, Bunnings or Kogan, you’ll get anywhere between 3 and 5 years of warranty on the frame and mechanical parts.

It’s OK on paper, but very poor when directly compared with ErgoTune Supreme’s 12-year warranty.

Worse, the warranty on T50’s seat cushion is only 1 year.

Take it as a strong hint about its durability. I’m willing to wager that it will sag, and you’ll have to pay for a replacement every couple of years.

No trial is available, either.

Even though the company promises one on its website, you realise it’s not real as soon as you read the fine print.


A trial that requires you to pay for the cost of return shipping and in an unused condition is not a trial. It’s simply an ACL-mandated return policy.

My Verdict About The Sidiz T50 Office Chair.

The Sidiz is not a world-beater by any means. Despite very good ergonomic features, a novel seat pan tilt feature and beautiful design, it’s not worth $600.

It’s a decent chair, but because of its poor build quality, it’s overpriced.

If Sidiz priced it at $400, my impression would be very different – and it would be a strong contender.

At $600, it’s not a great buy.

You can buy an ErgoTune Supreme for the same price and know deep in your heart that you’re getting exceptional build quality and an even stronger set of ergonomic credentials.

Or you can buy a Sihoo M57 for half the price.

This is unfortunate, because the Sidiz T50 is an attractive piece of furniture. It’s a chair that looks like a statement piece, but isn’t. You realise this as soon as you touch it.
