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

Reasons To Buy The Sidiz T50 Office Chair.
Above: Sidiz T50 in white. It looks stunning in a modern home office (like mine, ha).
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.
(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.
Expert Tip.
The T50’s armpads will get easily scratched by a cheap standing desk without an anti-collision system. If buying a standing desk, check that it has this feature.
Above: The foam cushion offers a nice balance of padding and ventilation.
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.
Important!
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.
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.
Above: Lumbar support is quite pronounced but not pokey.
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
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.
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 Joobie instead).
Important!
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.
Instead of hearing and feeling satisfyingly clicking sounds, you get notchy, rough movements.
The Sidiz is not nice to interact with.
Above: Sidiz T50’s armrests look attractive from a distance but feel flimsy to the touch.
The minimalist frame doesn’t have enough strength to cope with larger bodies.
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 5/6-year warranty.
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.
Above: Headrest adjusts for height only.
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.
Important!
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.
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 Joobie 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.

Hi,
Do you know 9am HOME standing desks?
I want to know how about their desk.
Steven McConnell says:
Hi Cody, I’ve never seen them before but I took a quick look for you and I’m 90% certain it’s another Jiecang desk. You can tell by the design of the feet and the lowest height (60cm). Desky, Omnidesk, Stand Desk are all pretty much the same.
Cody says:
Which one do you mean? Pesk or Robin series? I am interested in their Robin series, it looks unique and beautiful. I can’t find anyone like it in Desky.
Steven McConnell says:
I was talking about the Pesk Series. Robin series does look attractive and unusual, but I’m usually not a fan of tubular legs as they tend to be more prone to wobble. I can’t say whether this is the case in this instance, as I haven’t physically tested the desk myself. The 10 year warranty is reassuring, however. I wish they offered a risk-free trial to let you test out the legs!
Cody says:
Thank you very much, Steven; I will take your comments into consideration.
Erin says:
Do you know much about Kangadesks? There are Australian as well.
Steven McConnell says:
Hi Erin, its another Jiecang standing desk. Same as Desky, Omni, Stand Desk etc. The design of the feet and 60-125cm height range gives it away. The desk appears to currently be currently on sale for $299, which is an absolute steal and I’m wondering why they’re selling their stock at 1/3 of RRP. Regardless, even if they’re about to go bust, I’d still buy one at that price.
EDIT: Be careful. Fakespot showed these warnings while browsing their website: “Multiple eCommerce scam experiences detected, Poor customer service”
Suzy says:
Hi – given all the desks are so similar, is it possible to mix a desk from one brand with a drawer accessory from another? I don’t like the UpDown desk metal drawer (hangs very low so likely to impede leg space) but don’t mind the Desky one – can these be mixed and matched?
Thank you for the reviews! Super helpful.
Steven McConnell says:
Yes, it’s possible to play switcheroo. But you may want to consider that UpDown design is curved, so it will hurt less if you do jam your thighs into it. Desky’s meanwhile, is quite angular. Pro tip: you can also find a bunch of inexpensive slimline desk drawers on Amazon.
jason says:
I’ve spent far, far too much time agonising over which desk to get haha, definitely more than a week. Very happy that you’ve added the omni-desk to your catalogue. That was the one I was considering the most untill you came you with a review saying that it was more wobbly!
Anyways, do you have an opinion on the new updown desk KLIK Series? Its advertises to be significanlty ligher while having better (on paper) specs
Thanks!
Evelyn says:
Hi Steven, great blog post – thank you! I’m also wondering whether you have any opinion or insights on the new UpDown Desk KLIK series…they come at $100 more expensive (for the same size/table top) but seem to be ‘better’ according to the UpDown website.
Cheers!
Steven McConnell says:
Hi Evelyn, thanks! I will have a full review of the KLIK up around February 2025. It’s not necessarily a better standing desk – but it is lighter, less bulky and promises easier assembly.
Ben Clements says:
Hi. I’m interested to know more about whether I actually could fit the Desky cable management system in the Omnidesk? I’ve had a look at the omnidesks in person at the showroom and it looks like their cable management trays screw on (vs the clip in at the edges of the desk with the Desky tray). The desky system also has the power plugs that snap into place in the tray.
So I’m curious to know if you have you tried it, and if so how did you do it please? Or is your thinking that you’d just buy the power boards and plugs from Desky and rest them in the Omnidesk tray?
I’m stuck, because I prefer the Omnidesks but I really love the idea of a single power lead!
Thanks
Steven McConnell says:
I just had a new Omnidesk delivered to my house. Give me about two weeks to assemble it, test it out and report back.
Sunni says:
Thanks for your very helpful (and funny) review. I used the information to to buy a Desky standing desk in record time – no consumer agonising for weeks, as is my usual practice. It has a pneumatic up/down mechanism, so lets see how that goes.
Steven McConnell says:
Ha! You’re welcome, Sunni. Glad I helped you cut down on the agonising. The pneumatic mechanism is an interest choice – let me know what you think of it?
Amber says:
Hi Steven,
Really great and insightful review. It was refreshing to see something that wasn’t filled with ChatGPT affiliate link garbage!
I’m curious about your opinion on L-shaped standing desks? I know that Desky, UpDown and a few other retailers offer these types of desks and I would assume they are more strong and stable, but I’m not an expert and I can also imagine the opposite being true due to the irregular shape. I’ve been looking at these types of desks because I think their shape suits my space the best. Do you have any knowledge on this or do you only have experience with regular rectangular shaped desks?
Steven McConnell says:
Thanks, Amber. Did you know that I have a L-shaped standing desk review? Search for “arielle best corner standing desks” and you’ll find it.
Melissa says:
Hi Steven great article thank you!
I’ve spent way to much time on this, and I’m now leaning towards the Artiss thanks to your review.
I’m wondering if you have any insight into ergonomic chairs for the home office also?
Steven McConnell says:
Hi Melissa, thanks! The Artiss is a great budget pick. I’ve written numerous ergonomic chair reviews – Google “arielle best ergonomic office chairs” to find them 🙂
tania says:
hey are there any other manual desks apart from the ikea ones you don’t recommend, that you would recommend? I prefer the idea of not needing electricity to move between stand up and sit down but maybe that doesn’t really exist?
Steven McConnell says:
Hey Tania, all of the premium brands (UpDown, Desky, etc) offer a manual crank model. Definitely the way to go if you want to avoid electronics. But TBH I suggest you reconsider. Electronics are very reliable these days – and hand-cranking your standing desk is more annoying than you’d expect.
Adam says:
Hi, do you know much about the UpDown Klik vs Pro system?
Steven McConnell says:
The company has shipped their new Klik standing desk to me yesterday. Stay tuned!
Scott Long says:
You mention in your review of the Up Down Pro that you would get the cable holes and grommets done, but it looks like your (very pretty) Messmate desk doesn’t have them. Is your recommendation a hindsight reflection, or did you choose not to spoil the look of the desk with the grommets? Without the grommets can you can still run the cables behind the desk and into the cable management tray? Cheers!
Steven McConnell says:
Scott, I said in the review that grommets and holes are a great idea, not that I have them. They’re less important if your standing desk faces a wall. But if you have an open-plan style home office like mine, they’ll make your workspace look much cleaner. PS You can still run cables into the tray without the holes and grommets – the cables will simply run behind the desk.
Isaac Jenkinson says:
Hello,
Have you had a chance to try the new UpDown Lyft model? Curious about its stability vs the pro.
Steven McConnell says:
Isaac,
Not yet. On first glance, it looks like a budget alternative to the “big brothers”. It’s probably pretty good (UpDown has a reputation to maintain), but I’m of the opinion that buying cheap means you pay more in the long term. I’d save up another few hundred bucks and get the Pro. You can often get a melamine or bamboo-topped model on sale for around $900.
David says:
This is a great site and will help me decide on which desk to buy. Have you heard any good/bad reviews about the Blacklyte Atlas Lite or Ergo-Rise II from BDO furniture?
Steven McConnell says:
David, thanks for the kind words. Never heard of the Atlas Lite until you mentioned it. Looks like a decent gaming desk that borrows heavily from Secretlab Magnus – but why not just buy a real Magnus instead?
As for the Ergo-Rise – looks like a decent desk, but its height controller is outdated. The best standing desk brands have upgraded to OLED controllers.
Ben says:
Thank you for writing this review Steven; really helpful to break through the BS.
By any chance have you used or hold an opinion on Vertilift desks?
Steven McConnell says:
You’re welcome. God, I haven’t even heard of them – but thanks for the heads-up. There are too many standing desks on the Australian market. Obviously I haven’t used these in person, but I’m almost certain they’re yet another Jiecang variant (i.e., frames are identical to Desky). You can tell by the identical max and min heights, as well as the design of the foot.
Eloise says:
Hey Steven, I was recommended the Alwyn or Octavia (Living Fusion) 140cm sit and stand desks from Temple and Webster which don’t even get a mention in your review. Would you bother with any of their brands ? (I may have dodged a bullet by finding your review!)
Steven McConnell says:
Hi Louise, I haven’t had first-hand experience with the T&W standing desk (must add one to my list!).
However, I had a look through the specs for you.
It doesn’t look too bad, actually – considering the price. If you can’t stretch your budget to ~$950 for an entry-level UpDown or Desky, this could be a good option.
Jordan says:
Hi Steven, Thanks for the review! I am starting out with a home office set up and need a new chair and sit stand desk. I’m a student but I prefer to buy things I know will last, but I don’t have too much experience with sit stand desks. I initially thought to buy the Artiss but have considered buying the Acacia UpDown Pro+ so I know it lasts and I don’t have to buy another desk in a couple of years. Is it worth the price jump for me? Thanks!
Steven McConnell says:
Hi Jordan, the Artiss and the UpDown desks sell at two very different price points. If you have the budget, I suggest you stretch to the UpDown standing desk – you won’t regret it.
jason says:
I know you’ve disqualified the flexispot e7 pro so the e7 max plus would probably also be disqualified, but a quad motor 4 column desk frame at a prices competitive with UpDown desk is incredibly tempting. Plus 15 year warrenty (if the company lasts that long)
Have you had a chance to take a look? Its like half the price of the desky quad!
Steven McConnell says:
Hey Jason, great observation. I haven’t included quad standing desks here because they’ve traditionally attracted a niche consumer – someone who needs to place a tonne of gear on the desktop and doesn’t mind paying 2X the usual price. But Flexispot’s sharp pricing on their quad desk certainly changes things. I haven’t seen one in the wild yet – but the specs look promising.
