Excellent chair and easy to put together :)
Still exploring the various adjustments, signs are good
Sick chair
It’s the best chair we have ever had
So comfortable. Lower back support is excellent. Previous back issues all but forgotten.
Did I finally find my dream chair? Absolutely yes. I have a lumbar disc herniation and I spend long hours sitting for both work and gaming. Over time, I’ve tried many chairs, but within just one month, none of them came even close to the comfort of the SIHOO Doro S300. Ahhh… that lumbar support… ❤️ It literally hugs my lower back like my lover. No joke — it supports you constantly and makes long sitting sessions feel surprisingly easy. Now, is it perfect? Almost. There is only one minor issue, but it definitely does not stop me from buying this chair again. The armrests… They’re… interesting. Getting them perfectly aligned feels like you need double PhD. They also rotate left and right, uuuuup up very easily, and there’s no way to lock them in place. A friendly salute to the engineer who designed these armrests 😄 That said — this is not a deal breaker for me at all. The SIHOO Doro S300 is absolutely worth it. Your back will thank you every single day.
I haven’t had a single bad thing to say about the chair, all the materials feel really premium and it’s night and day with some sub 500 chairs
Incredibly comfortable, properly supports my back and feels like a hammock when laid back
Great chair but the hydrolic elevation was a bit low even on its heighest setting. Otherwise a great chair
Nice chair but the arms keep moving, and cant fix the back tilt. apart from that very comfortable
Get one, they are great.
The chair was ok with an innovative design it was just a bit narrow for me and sitting with ankle on knee was difficult. I also had issues with the general level of quality v price from a longevity perspective. Item has been returned no problem however I have yet to receive my refund ..
Great chair very easy to assemble
Easy to put together, very adjustable and comfortable.
Easy to put together, well protected in box and love the chair. Feels very sturdy
That was a birthday present for my husband. He loves it, great functionality and very well made. I already own a previous model and I can recommend 100%.
Excellent chair, I couldn’t be more pleased. Not only is it practical and comfortable, it has every adjustment I need and many more. Plus it’s elegant, making the rest of my home office look rather drab. Only criticism is the web site and information on Amazon - it doesn’t do the chair justice and made the decision process somewhat longer.
One of the best chairs I have sat on and used over 30 years.
The Sihoo Doro S300 'Gravity-Defying' Ergonomic Chair truly lives up to its name with its innovative design. From its sleek appearance to its comfortable functionality, this chair provides excellent lumbar support and promotes proper posture. Its adjustable features allow for customization to suit individual preferences, making it suitable for long hours of sitting. Overall, the S300 is a top choice for anyone seeking both style and comfort in an ergonomic chair. Next level compared to already great Sihoo chairs.
I��m 240 pounds and 6��1 and I love the chair, it��s perfect with my height adjustable desk also. The only thing is that the frame size prevents me from sitting with my legs crossed but that��s not a deal breaker
Looks nice, but for this quality the product is overpriced. Flexibility is not good enough for someone of 155cm tall. the seat from hard tissue, and plastic front part hurts me under legs when sitting longer than 30 min. In addition the boxing is very poor and old. Looks like I was delivered a returned product (2nd hand product). The plastic parts of the chair having lots of dirty spots and the tissue having specific spell of cooking. I also ordered 2nd chair model- S300 in black and didn't have a discount.
The back side can not stand up by itself
Schneller Versand. Wirklich gute Abwicklung.
After two weeks of trying it out, I can say with certainty that this chair is not at all comfortable and in fact has destroyed me waist. I am in pain right now. I was not having issues with my waist before this chair. From the first moments sitting on this chair, I felt awkward. The bottom mesh sinks way too much, and the two waist pieces feel really uncomfortable. I tried switching the positions of both seat and waist-supporters for days, but could find a comfortable setting. After the first day of use, I started feeling pain at waist, back and pelvis areas. After a week the pain was intolerable. I used quite a lot of ergonomic chairs in the past, my last one was an Ergohuman chair, and I had not experience so much discomfort, let alone pain. I even let other people sit on it, and their experience was similar. My weight is 95 kilos (210 pounds) by the way. This is a very expensive chair and it just does not feel expensive or deliver the comforts it advertises. I cannot recommend this to anyone.
Will be returned. Build quality is appalling for the price point. I got the basic model. The leveler is broken, therefore I was not able to adjust the depth of chair as advertised. Lumbar support is decent although the second leveler was able to adjust how far it leans back as advertised. In addition, to the restock fee charged. This is ridiculous considering that it came broken!! Update: Customer service resolved my issue and reassured packaging will be fixed for future customers.
I've been using the premium ergonomic chair, the Sihoo Doro S300, for several weeks now, and I couldn't be more impressed! The S300 is a marvel of ergonomic design, truly representing the pinnacle of Sihoo's offerings. The chair's comfort and superior quality have surpassed all my expectations. Its standout feature, the Anti-Gravity Mechanism, crafted with aerospace-grade glass fibre, provides a weightless recline experience that feels like defying gravity. The synchronised support while reclining and the dual dynamic lumbar support offer unparalleled comfort and assistance, making long hours at the desk effortless. The soft, spacious headrest adds an extra touch of luxury, perfect for moments of relaxation with the smooth weightless recline. It's no surprise that the Sihoo Doro is a German Design Award 2023 winner. This chair is not just a piece of furniture; it represents an investment in comfort and well-being. For those seeking a top-tier ergonomic chair that truly delivers on its promises, the Sihoo Doro S300 comes highly recommended!
Easily put together with U-tube help :) Comfortable, futuristic-looking with many adjustments.
Brilliant chair. So comfy and aesthetically pleasing. Easy to put together. Very quick delivery. Absolutely brilliant
A slight issue with 2 of the screws, but other then that, everything was like expected..
I'm a 1,95mts man and the chair is (almost) perfect! :-) It's steady, molds my body overall, its arms can be set to different positions, and it's very, very comfortable. 2 minor remarks to mention that, although adjustable, I wish the seat's length could be a bit bigger and when I sit straight, there is a minor slack of the seat I recommend this chair to everyone
Hi, there was a problem with the packaging and I was informed by the logistics provider that the package was in a really bad state. I didn't receive it as they say there were parts falling to the ground. I would advice to improve the packaging experience and quality, its the first thing we see. Also, I would like the refund or resend me the same chair. Thanks
This chair has so many innovative ideas built in. I have found it very difficult to find a comfortable chair due to osteoarthritis and need one that is soft yet supportive. This one has so many possible adjustments and is allowing me to be able to do my pc gaming in comfort.
I��m 240 pounds and 6��1 and I love the chair, it��s perfect with my height adjustable desk also. The only thing is that the frame size prevents me from sitting with my legs crossed but that��s not a deal breaker
I got this one on sale for 660 and that price tag is the maximum I'd pay, hence the 5 stars review. Tested for few days sitting for 8 hours. Does the job well. Great customization, easy to use and assemble. Castors could be better.
The recline tension knob does not work. The position of the seat does not lock in the forward position. The seat in general is too small for a person who is 191 cm, the seat not wide enough and the lombar support cannot be raised enough to have a comfortable seating. For this type of budget it is I would say disappointing. The general build is of good quality, the delivery and assembly quite straight forward. From engineering point of view there should be different sizes or more way to adapt as nowadays it is common to have tall persons.
The new chair for my studio is s300 Fast delivery Very easy assembly Now will test it over the next month Very pleased
Like it a lot
I am proudly owner of the S300 and i can say this was the best payment i could ve done towards my back health. Feels like a blessing always i sit on it. The materials feel very high quality. Only one thing i havent figured out yet is the head part, i dont know how i m supposed to support my head when laid to the max lvl backward there is no pillow or anything similar to it, just looking straight to my celing. I m 1,85 m. Everything was maxed out so i could try to look at my monitors while laying on the chair, but it was just not possible as i wished for. But still no doubt this chair is a Throne for the Kings and Queens.
I have received the wrong product, I am very unsatisfy, you send me the C300 ! and I have order the S300. I am still waiting for solution . Please come back to me asap.
