Doro S300 Ergonomic Office Chair, Computer Chair, Dual Dynamic Lumbar Support, 6D Coordinated Armrests, Adjustable Desk Computer Gaming Rolling Chair (Black Italian Velvet Mesh)

I have to say I was sceptical about buying this chair, I have had Aeron Millers previously so this chair had a lot to live up to.I work from home and spend all day sat at my desk so having a comfortable chair with decent support is really important and worth paying a premium for.The chair does require assemble but the seat and the back with all the mechanism are together as complete units so it was simply a case of bolting the base together, dropping the seat on and then clicking the back into place. I'm not practical at all but it came with good instructions and all the tools so job done in 20 minutes.The build quality is good, all the main support frames in cast aluminium.The mesh material is really high quality, soft to the touch and breathable.This chair is 'very heavy!'...feels quality.When I first used the chair it was 'OK'.....comfortable but not quite as good as expected, "however" I realised the points of articulation on the chair are mind blowing so I set about making adjustments to fit me. The seat slid forwards giving more depth. the back raised up and the lumbar support adjusted forwards. Even the arms adjusted in every way imaginable. The bottom line is that after taking the time to set the chair up properly to my proportions it felt great, very comfortable and very supportive. Love it!All in all, a good purchase and I'm very happy with my choice.

I recently purchased the Sihoo S300 chair from Amazon, and I couldn't be happier with my decision! From the moment I started assembling it, I could tell it was a high-quality product. The instructions were clear, and all the parts fit together perfectly.Once set up, the chair exceeded my expectations in terms of comfort and support. The adjustable lumbar support and headrest make long hours of sitting incredibly comfortable, especially during work-from-home days. I love how I can customize the tilt, height, and recline to fit my exact preferences. The mesh back is breathable and keeps me cool even during extended use.In terms of design, the Sihoo S300 is sleek and modern, fitting well in my home office. It feels sturdy and durable, even after weeks of daily use. For anyone looking for an ergonomic chair that offers great value for the price, this one is a fantastic choice! Highly recommended!

After purhasing a product we tend to forget the importance of customer servervice unless there is a need.I have been incntact with SIHOO and I have to say I have been pleased with the customer servece. The 5 star rating is purly for this reason. You are not going to find reviews about customer service in Youtube about SIHOO, so I thought I should include it with my review. Pleasent converstion via email, its not instant as this is aftrall email converstion I have to say im very satisfied with the outcome. Hope this helps.

I think this chair looks great and it has helped with my back pain while sitting and working. I would highly recommend this to anyone.

I had high hopes for the SIHOO Doro S300, especially given its sleek and modern design. Aesthetically, the chair is definitely a standout—it looks professional and well-crafted, fitting nicely into a home office or corporate setting.However, functionally, it hasn’t quite lived up to expectations. One of the biggest issues I’ve encountered is the back tilt resistance. It’s surprisingly weak—even when adjusted, it feels like the chair tips back far too easily. For an ergonomic chair at this price point, I expected a more secure and supportive tilt mechanism.The setup process also left something to be desired. The "out-of-box" assembly wasn’t as straightforward as advertised. I’d strongly recommend having at least two people on hand during setup to avoid frustration or missteps.Overall, while the chair scores points on looks, it misses the mark on key functionality and ease of setup. With a stronger tilt resistance and more intuitive assembly instructions, it could be a much better product.

I watched the commercials and thought this chair should be good, but my expectations were not met.It is too flimsy, the armrests are too easy to change their position and are impossible to secure, some bolts and nuts are constantly falling out of the chair. Today one of the armrests jammed, I can not lower its angle, unscrewed the cap and took out the head of the broken bolt from the ratchet. I have no idea what function this bolt performed, but the build quality is very mediocre.The chair itself has scuffs and scratches since delivery.The backrest tilt mechanism has a hard, uncomfortable flat position, a slightly tilted position, which is almost the same as the first, and a completely lowered position. There are no intermediate positions, and this is very annoying, because every other chair has them. The role of the lumbar section of the backrest is also unclear, no matter how I change its position, my back hurts.
