Great relief on back pain.
This is a really comfortable chair as I sit in front of a computer 6 to 8 hours a day. I do wish the arm top would lock in place but it slides back and forth on it's own.

Sturdy & Stylish
This chair is well built and sturdy with excellent fit and finish. The back is supportive; however, the bottom is a quite firm when new out of the box. It does break in slightly over time - if you’re looking for softness of a pillow underneath you, this isn’t your chair. The mesh fabric allows for great ventilation. All materials including the metal and mesh fabric are high quality and should last for years. The height and tilt adjustments work very well.

Video Instructions WRONG don't waste your time watching it
Ignore the video instructions! Use the printed instructions. No KT6x13mm screw provided! video Instructions state: "Connect the backrest with the elastic plate using a KT6x13mm screw." Also no 4 M6x25mm screws provided as in video. Also video states to "Connect the tail plate to the backrest using 2 (TINY) KT4x13mm screws."! When in reality the printed instructions state to use 2 m8x35mm screws which have a MUCH better chance of not completely falling apart!

Very comfortable ergonomic chair, perfect for back support
I bought this ergonomic chair for my dad for his office use, he always have backache problem, he said this chair is very comfortable and it’s good for back support, the seat cushion it’s harder than the traditional mesh cloth, but it’s good for long seating. The seat is adjustable, and this chair is very easy to assemble. Very happy with this purchase, so happy that my dad love this chair, great gift.

Best Ergonomic chair ever purchased!
I have tried numerous type of ergonomic chairs, ranging price from $200-$1k. Thus far, this product captured the design I want the most. As a huge contemporary taste in design. This Sihoo brand was a perfect match to my furniture styling. Not only was easy to assemble...the chair is also very comfortable.

Looks good, but not as comfortable as some of my previous chairs
I bought this chair for 2 reasons. First, it looked nice. Second, it was made out of material such that it would not tear. Both of those two reasons are true--it does look good and it will not tear. However, I now find that chair is not as comfortable as some of my other chairs. When I lean back there is resistance pushing me back into place. As for putting the chair together, it did not have too many parts but it did take longer than I expected (maybe 1-1.5 hours).

This chair was easy to build, it has good lumbar support although it cannot get adjusted but if sit all the way against it, its good. The headrest adjustment is fine for me at 5’ 8” good neck support with height and angle adjustments. Armrest is a little short and only have up and down adjustment.

I am highly impressed with the chair's lumbar and neck support, which provides excellent alignment and a genuine feeling of full-spine support during extended use. Unfortunately, the seat cushion and pneumatic height-adjustment mechanism feel excessively firm for my body weight (160 lbs). While the density is initially comfortable, noticeable discomfort in the sitting area develops after approximately 1–2 hours of continuous use, making all-day seating challenging without additional cushioning. For that reason, I will be returning it.
