I have a Sihoo M57 & I'm quite happy with mine… Had it for over 12 months & no issues… I find it quite comfortable

Keen to grab the M57 when its next on a decent deal. Havent been able to find one in person to test out. How do you find the adjustable lumbar support? Did you grab a cover for the mesh seat at all?

Combine this with Ozempic. It will last much longer.

Is that because Ozempic use leads to lower life expectancy, thus in comparison the chairs service life will be greater?
I also gave you a +1 for your comment. :-)

LOL I was thinking that lower weight on the chair would make it last longer.. :)

@Naigrabzo: There is that. May be there is a formula that encapsulates use, weight loss and life expectancy or other detrimental health-outcomes. haha.

@Naigrabzo: I've read that it def helps you live longer as does straight up losing weight. But my reply was to the person who said it lowered life expectancy.

I had to upgrade to an ergotune since it was hard on my tailbone after extended hours. Im on the taller side though so that could be part of the reason tbf

The backrest tilt no longer works on mine. Bought in June 2025. Thinking of returning it. I guess better for my back instead of leaning backwards all the time.

Great lumbar but for me the seat is too hard. I can feel the solid underboard after a couple hours.

are they cheaper in store?

I’ve never seen sihoo in Costco, they seem to be online only through distributor.

I prefer Tecca chairs

I swear I have the worst pillow in town

You have definitely been in a mall!

Where do you buy these from in AU?

Anyone know any stores that have demo models in NSW?

@alexyfyf - Thank you for sharing this deal and congratulations on your first post 📯 🥇. Keep it coming.

Thanks for congratulating

Congratulations on your first time thanking the congratulations.
It seems life is not all suffering after all :)
I think it might be after reading those three comments.

Anyone has had this chair for more thab 1 year? How does it hold up?

Purchased the M57 chair back in Jan (M57 is mesh covering for breathability) can say it was a major and modest upgrade from my previous chair. Liked the adjustable and armrest support features. Its a decently comfortable chair esp for its price. Really have no complaints about the chair. Herman Millers are always king though.
One thing to note about the chair though is that given that it is a mesh covering and not a solid material, after a few weeks of usage, there will be a significant amount of dust collected under the mesh covering. That is my only complaint however. I am an average sized person so if you're a bigger and taller person it might be wiser to find a different and bigger chair.
PSA: If anyone does end up purchasing directly through SIHOO's website; be wary of potential invoices that may arrive in your email, as I received an invoice 2 months after my initial purchase describing the purchase of 4 M18 chairs. I was not charged for this invoice but keep that in mind when buying online. Perhaps using an alternative email and a payment method that is highly protected against potential malicious vectors.

Money laundering

you should enquired for the 4 chairs

Anyone own a Steelcase here who has also sat/owned this before? Please share your thoughts.

Steelcase Gesture > M18
M18 isn't as good
Have the Sihoo M57 Pro now, the footrest is nice, head rest is a little too much. and the lumber support is kind of mid.
I'd compare the Gesture to be a little better, only because of the customizability.

comparing a thousand dollar chair to something 1/4 the price? you're kidding

assuming money is just a number lol

@AnnoyingEshayLad I mean, the same thing can be asked about Dyson vs Dreame vacuums right?

Steelcase is nothing compares to SIHOO. I have a M90. It is much more comfortable than my Stealcase series 2. And much more cheaper.

Can anyone recommend an affordable ergonomic chair with ventilation (similar to cars)?

M57 coupe

Is this a joke?

Yes.
He means the SIHOO M57.

thinking about the chair company tv series now lol

I simply cannot picture Tim Robinson without laughing

I have this chair at home. Very comfy, though I would have loved for the upper headrest to be adjustable fore and aft.

Had this for about a month, pretty good for its price.
Seat cushion is dense, slightly firm side with prominent "crotch mountain". Not uncomfortable at all. Can fold 2 of my legs in for that super Un-ergo position.
Headrest is good, doesn't catch hair, feels soft enough. Good range of adjustment forward and up.
Lumbar support is where it falls imo. It's quite firm, protrudes abit even on the most recessed level. I moved mine to the very bottom where it barely touches my back. Might be an issue for shorter people, might find it too aggressive and annoying.
Not as confy as the Mirra 2 chairs we have at work, but it's not bad either. Could use more adjustments but I get these are barebones

Mirra 2 chairs
Bro actually compares chairs that cost up to 10x more

How many people here would buy a new Herman miller or even a 2nd hand one, always good to reference it to the best out there where people have most likely have sat on one at work.

where people have most likely have sat on one at work
Doubt, is my point.

ignore him/her. Good review thankyou for sharing

Can any shorties give some user experience on this chair?

I'd go a sihoo m57 pro over this for a mesh seat.

sorry mates, Capacity: 150 kg

Looks like this has expired.

Just remember folks, it ain't truly ergonomic unless it complies with Aus Standard AS/NZS 4438. Can't see any evidence that this one does, so that's a hard nope from me!

… and just to add, AFRDI "blue tick" certification also designates compliance to this standard.

It’s a good chair, if you are over 6 foot the back may be slightly short. That’s my feedback on it.

Can anyone compare to these?

All look similar in functionality and comfort?

You must be craze bruh buying from Kogan
Even then govamant troops don't buy from hea

Any decent price on Sihoo M57?

Wait for Bf

I can't wait for the boyfriend.

Thanks OP - ordered 4.

For those wondering, they aren't available in store in either of the Costco stores. The rep said that it is an online order only so you won't be able to try before you buy.

You can always return to the store if you are not happy with it.

In WA, I mean.

any recommendation for someone around 161cm tall (5.2 foot)?

Should try steam chicken breast with added hormones

New to Costco, looks like I cannot use Costco gift card to purchase this?

now i stand up more than 50% of the time for desktop works.. chairs are not as important as they used to but this is a good chair at an affordable price…

Is this better than Ergohuman?

For $200 it's decent.
My recommendation, for a chair, is a second hand Aeron obviously, but if you want to be able to sit in different positions and have a bit more flexibility, Steelcase Leap V2 for $300-$400 second hand WAY worth it over these PeePoo chairs
How can I get a decent price second-hand Steelcase Leap V2?

Garbage chair if you are 180cm+ ,
Buro Metro is a good base model chai imo


Any feedback on how they perform with prolonged use, some bases are rated for 8+ hours
