Doro S100 Ergonomic Office Chair with Dual Dynamic Lumbar Support

This is an excellent office chair by SIHOO. My partner uses it and reports it's very comfortable. I want to share some notes I made while assembling this chair.* You need to have some upper body strength to lift and maneuver the chair portion onto the gas lift. Don't be too proud to ask someone for a hand.* Do NOT throw away the box! You need it for when you're attaching the seat and back to each other.* The instructions are packed inside the bag that holds the seat.* The instructions are in English, German, French, Italian, Spanish, Japanese, and Arabic.* There's a QR code in the instructions for a video showing assembly. Make sure you check the video's description for a link to the updated video.* Personally, I found it confusing when the printed instructions and the video demonstration both changed perspectives occasionally. Maybe you might, too.* This comes with white, cloth gloves, but they're on the small side.* The only tools you need would be something to get into the shipping box. I used scissors.* There are extra bolts and washers.* There are 2 sets of Washers J, but you use 4 at a time.* If you're looking for part P, the Decorative Cover, it's probably already on Base K.* The arm rest pieces come in a box, and if they're wrapped in different colored bubble wrap, it doesn't mean anything.* If you don't want your chair to have arms, feel free to omit them.* There are 5 black plastic pieces that have no part designation in the instructions. They go inside the silver…

Love that the chair is so configurable, the seat slides backwards and forwards, height (Of course) - seat back adjusts up and down, arms slide forwards and back, adjustable height for the arms, just wish you could lock the rotation and actually lock the arm height. It's on a vertical ratchet, 4 clicks upwards then it resets and can drop back to the bottom. That's just a personal preference though and doesn't detract from the overall review of the chair.

I selected this for my son who was in need of a chair for his desk (mostly for playing games). I had purchased a gaming chair for my other son that had a lot of issues, so I wanted something with a more simple design. This chair was easy to assemble and really looks nice, quite modern. My son has been using it for a month or so now and seems to be very happy with the comfort with no complaints (although his brother's gaming chair definitely has some cooler features). The adjustments seem smooth and everything just works. Overall a great office chair option but the price is a bit steep.

I was impressed by the comfort of the seat cushion. The width and thickness of the bottom make it soft and hard, and it doesn't feel uncomfortable or digging. The width adjustment is very smooth, and it is easy to find the best position for your desk and height. For a detail-oriented person like me, the design is really thoughtful. The tilt adjustment of the backrest is a bit a bit. Although the adjustment range is sufficient, the installation support of the backrest is not so uniform at some extreme angles, which makes it feel a bit awkward. In addition, the time spent on this chair was amazing. The icons on the manual are not very clear. It is possible that I was a little confused and could only operate it intuitively. However, after installing it, all problems disappeared.

This chair works for me very well. The best part for this chair is the 2-piece waist support. That makes my back very comfortable. The second good point is the recline feature. You can choose to move free or set at a fixed position by pushing the lower handle inward. The mesh structure fit my body perfectly, at the thighs, waist and the back. The heights of both the backrest and the armrest can be raised. It is fancy that when you raised to the highest level, they will go to the very bottom then start over again. I like to set everything to the lowest level, so I can keep my head straight. It is a pity that the seat can only set flat or move forward. If let me wish, I would wish the seat also able to recline.The installation is not hard, but you need to have mechanics experiences. The instruction is not easy to understand, especially the figures are too small to see the details.
