Customer Reviews
Overall rating: 4.5 / 5 from 280 reviews.
I am enjoying it . Very comfy
Didn’t except to be honest to receive it quickly first of all. Talking about the chair, love the design, so comfortable, my son absolutely loves it. I was not expecting something like that seeing mixed reviews. Don’t get it, I had the best experience so far. Totally recommend.
It's a nice chair and I'm happy with it. Not sure if the footstool is worth the £40 I spent on it to be honest, in fact it definitely wasn't. And it's disappointing to receive the chair with a black mark on it from damage.
Product came in large box, the components of which were very thoughtfully packed to save space and reduce scratches/damage. Instruction sheet was mainly by pictures which on the whole was simple to understand. screws/bolts/washers were grouped in vacuum packaging and clearly code labelled. Because an extra item was supplied for every type of screw/washer/bolt, there was less chance of customer dissatisfaction . . . . well done Sihoo ! . . . .nice touch Sihoo. Another big positive was that an Allen key was provided. It was moulded with a sturdy oversized plastic handle and this was the only tool required to assemble the chair. 1st impressions make a huge difference and the packaging alone shows how serious a company cares about its products and customers. Chair took approx 45min to assemble at a relaxed pace. I've been using for almost two weeks and really appreciate the lumbar support it offers. It has also improved my sitting posture and I would say the foot rest is a must have. The chair has a metal subframe which adds to its quality feel. I would definitely recommend Sihoo chairs especially since the price is very competitive.
I took some time to assemble the chair and there was one tricky bit. It is no good tightening the 3 big nuts until the holes for the other fixings are aligned! Once it was assembled it was love at first sight. It is of course extremely comfortable and supportive but the adjustable armrests allow me to stow them neatly under the desktop and above the keyboard tray.
Very good very high quality
Very comfy so far easy to build comes with all tools needed
Nice
The chair is fine, but the product arrived with a lot of scratches as shown in the pictures.
⭐ Sihoo DORO C300 Chair – My Honest Tea 🍵 ⭐ Right, so first off – despite the packaging looking like it had been through a bit of a bar fight 🥊📦, I got some compo 💷 and been told me to keep it if the chair was fine. Spoiler: it was absolutely fine. ✨ Assembly? Easiest DIY moment of my life – no tears, no swearing. Literally a breeze 🌬️. Big up for the gloves included too 🧤 – this girly appreciates not breaking a nail. 💅 After a few weeks of working like a gremlin on caffeine ☕💻 and gaming with the mates 🎮, my back and bum feel… nothing. Which is actually everything. No aches, no pains, just pure cloud-9 comfort ☁️. When I recline, I swear I’m basically in bed 🛏️ – dangerously comfy. Only tiny cons? • I might cry the day it breaks, because I’m genuinely attached 🥺 • Mesh fabric is chef’s kiss for airflow 👌 (skiing vibes ⛷️), but if you’ve got cats… well, they might think it’s their new scratching post 🐈💔. Verdict? If this chair had a dating profile, I’d swipe right every time. 💘
Lovely chair, thank you
Just wanted to give a shout out regarding this amazing chair! As a chronic back pain sufferer, I find this office chair to be an amazing solution. It’s tough to sit 8 hours a day but this chair gives me great comfort. It’s breathable and provides amazing support! In addition it’s not too pricey and provides an aesthetic look. I highly recommend!
Super comfortable chair with quality materials! The wheels are awesome as well, easy to roll over from my desk. Good seating position and lumbar support! The armrests have a good form as well, however they are a bit too easy to rotate, so you'll have to set the angles from time to time, but overall a great choice, I'm happy with my new chair! :)
I used to have another chair by Sihoo, therefore decided to give a try to Doro 300. It‘s important to have not only breathing back, but bottom as well, specially during hot summer days.Could not be underestimated the quality of materials. Rollers are more quiet than usually for these price range. Backrest support is surprisingly good, as it automatically adjusts to your position.So far one of the best quality for such price range among competitors.
this is an ergonomic office chair, it’s made of all breathable mesh panels (seat, back rest, head rest and lumbar support) not only professional looking but also very comfortable and particularly good for summer, stay so cool even for a full day workingit came in a very big and heavy box, the chair is much heavier than expected, probably near 30kg! not hard to assemble with the video instruction though, but was a real pain to move it to my study upstairs because it’s big and heavy!this chair is really ergonomically designed, almost every single part is adjustable to adapt to fit my weight and posture, particularly i like the armrest, stand out from other office chair, besides up and down, this armrest can adjust back and forth, angle inward or outward, and even follow when the back reclined! good support all over and really comfortable to usei’m very satisfied with this product, would recommend
Das Bett der Sitzfläche ist sehr weich und ich bezweifle, dass dieses über Jahre hinweg einer Belastung über mehrere Stunden am Tag stand halten kann. Insgesamt wirkt der Stuhl klapprig und im Detail nicht schön verarbeitet. Die Armlehnen wackeln deutlich und verstellen sich im seitlichen Winkel ununterbrochen. Ich wollte den chinesischen Produkt eine Chance geben, muss jedoch feststellen dass dieser meine Vorurteile bestätigt - leider. Lieber ein wenig mehr Geld in die Hand nehmen und eine vernünftige Qualität einkaufen. Bei einer täglicher Benutzung von 8+ Stunden in Home-Office ist es die Investition auf jeden Fall wert.
I wrote a review that doesn't show because below 3 stars
I bought it to my husband because he has pain in back, he likes it very much, and it is really very modern, comfortable and good looking. White colour is more light grey and very easy to clean
This chair is Pretty easy to assemble. The manual is easy to follow and makes it so much more satisfying once you sit on it after setting it up. Looks well built, contemporary and lots of adjustments.It provides excellent support to neck and back. You won’t even need further accessories for your back as it comes with the cushions already to support where needed. I can literally be in the chair for 8 hours straight with no shoulder pain, my back pain has significantly improved since and my neck doesn’t get stiff anymore after sitting long time.Find it very suitable as general computer/office chairs when doing homework etc. very smart design and offers more degrees of freedom than the commonly available.Overall great quality chair at reasonable price. Highly recommend it.
After doing quite a bit of research, I settled on this particular chair and I’m very glad that I purchased. it was a good value for the money and it is very comfortable. I do like that I can recline in it as much as I want just by leaning back a little bit. I would definitely buy it again!
So far I love the chair. Let's see if it stands the test of time, but very satisfied so far!
The chair looks pretty good, but the armrests adjust by touching them lightly�� and the headrest does not lock securely in position. The casters are terrible.
The chair is good: the materials are high-quality, the assembly is clear, but the seat is uncomfortable and digs into the my skin - I returned it after 2 days of use.
Loved the chair easy to set up and although i couldve spent more on the pro model i think this is perfect for my needs.
.
It's not quite as good as my ergo, human. But for the money it's exceptional value , and a great chair to spend 18 or more hours a day.
Excellent chair, easy to Put together and very comfortable
Fantastic Chair totally recommend! Glad I followed recommendation from some of the influencers on instagram who promoted it.
A good value and comfortable office chair. Assembly was quite time consuming. Wish I had the foot rest!
Great chair!
Good chair
Really well packaged, clear instructions and the construction is well thought out and the seat feels really solid once built. Supremely comfortable, and really appreciated the mesh in the recent heat wave. Superb!
My wife really likes how it matches her white desk! Feels comfortable and well built!
I brought the Sihoo C300L chair for my home office, and so I am using it all day. It arrived in good time, neatly packed with all the parts and instructions to assemble it, including one extra of every bolt and washer. The assembly instructions were easy to follow and I had it done in no time. I am really pleased with the chair which is well built and sturdy, and very comfortable. Definitely recommend it.
Arrived really quickly, no problem with getting a VAT receipt and I love the chair.
Great chair, comfortable
I just went for the basic Doro C300 and it's a really good chair. Fully made from a thick mesh polyester fabric. I love the lower back support and the flexible headrest function. I would highly recommend it
Good chair
Excellent quality
