5 stars — Outstanding after-sales support After 18mths of hard use, I had a warranty claim for a minor gas lift issue on my DORO-S300 chair. Shaena and the Sihoo support team were friendly, responsive, and genuinely helpful from start to finish. They arranged for a replacement part quickly, sent a helpful install guide, and followed up to ensure everything was resolved successfully. The replacement was easy to fit and the chair now works perfectly again. It's rare to get this level of care with after-sales service — thanks Sihoo!

great
I love how this chair keeps me comfortable throughout my daily work. It provides great support, making long hours at my desk much more enjoyable.
It’s built well and good for my room. I love that it’s superb in quality while not costing a fortune because of discounts.
Seamless transaction. Easy to assemble. Provides excellent ergonomic support for long consulting days with much leaning forwards to examine patients.
Very good chair.. support is good.
I am so glad I decided to retire my faithful old leather recliner made locally 22 years ago with the S300. I’ve lived in it since it arrived 4 weeks ago
The chair is comfortable and is well made with good support systems. The order arrived quickly and was well packaged and sealed simple to put together
It’s good!
Great service, love the chair I spend a lot of day sitting down and this chair so comfortable and supportive
Very comfortable
Very happy with the chair as I’m able to adapt many things especially the lower back support. The main thing I find annoying is how the arm rest’s swivel as I find myself knocking them out of place. It can be difficult pulling it into the desk when you are sitting on it. Overall I’m very happy with it.
Totally love this chair - to be honest though would never had looked at it if it wasn’t discounted - love love love all the features thank you so much!
It’s a great chair great support for your lower back. Pretty much sit most days reading and gaming. Give me total support. Its a choice You’ll never regret.
The most comfortable office chair I have ever owned. I can sit in it for hours without any back or shoulder pain, unlike my old cheap chair. Very easy to assemble, and didn't take long to adjust to my height and size.
Recently had lumbar back surgery so was looking for something supportive but without pressure directly on the spine. This was perfect, although I regret not getting the foot rest.
Great for my lower back. That's the main reason for purchasing this model. Had it for over a week and it's great. Worth the extra money over cheaper chairs
Very comfortable and stylish. Love mine
10/10
Delivered on time and hubby getting used to it but loves it 😁😁😁
Happy with chair, it was well packed fotunately as I saw the courier dryer dropping it from the truck without using a back lift
Very comfortable chair
Worth the price, really comfortable
This was a gift to my daughter who spends a lot of time writing and researching. She is super impressed with the quality and versatility of the chair.
Very nice chair
A+++
Good chair, very adjustable.
This chair is really comfortable to sit on, totally worth the price!
Amazing chair!
Very comfortable and good adjustability. Would be better with a headrest, and the footrest is not quite rigid enough, but still a 5 star rating overall.
Extremely comfortable chair. This is the most supportive chair I have ever had! I would highly recommend to anyone
Great quality, Great chair, Great buy.
Loving this chair! So happy with this purchase…
Just got the Sihoo S300 and it’s honestly a solid chair. Build quality feels premium, the recline is smooth, and the mesh is super breathable — no sweaty back after long sessions. The lumbar support actually works and adjusts as you move, which surprised me. Only downside is the armrests — they move a bit too easily for my liking. But overall, for the price, it feels like a high-end chair without the $1,500 tag. No regrets.
Alternative to Herman Miller comes with polish frame and headrest.
Herman Miller replacement for me save on polish chrome upgrade and head rest is integrated. Super comfortable and able to power nap in the chair. Warranty is not as long at 3 year I think.
Very comfortable for long session, good lumar support
Absolutely love it! Efficient and more comfortable to use it for long hours.
Love the chair.is just so comfortable
Great office chair with lots of adjusts to get just the right fit. It would be perfect if the arm rests could be totally swung out of the way if desired.
