Soji office chair

A very well built chair with the adjustments I expected. The 12 year warranty, free 30 day return policy and review by BTOD convinced me to get this one. It was pretty hard to find more information about it or reviews, but it's definitely a hidden gem in my books. I've tried some more expensive ones like the Aeron or Ergocentric chairs but wasn't really "wowed", this one satisfies me for a reasonable price. I really can't find anything "truly" wrong with it.

Just to help others out, I am 6ft1 and 190 lbs for reference. The top of the chair feels ever so slightly too small and the seat depth adjustment could use an extra half inch to make you feel like it's absolutely perfect for my body. However, the upper limit of what this chair was designed for is 6ft2 from my understanding and it may be that my torso is slightly longer than normal for this height range.

The mesh hugs you once properly adjusted and the lumbar support doesn't poke into your back. The seat depth is just about enough, even if I would have liked the extra half inch. The 4D arms are highly adjustable and a great height.

This is an all around great chair that can't be beat for the price.

Great home office chair

After doing a lot of research, I decided on this chair as it is a great value for the quality and features you get compared to other chairs in its price range. My first impression was how well built it is. It feels so solid and sturdy compared to any other chair I sat in at a big-box office store. The seat feels firm at first, but after a full day of sitting on it, I realized that is not a problem and I was still comfortable. The pad will probably never wear out. The adjustments are easy to use and my back feels very well supported, especially in the locked position. The lumbar support is good, you can move it up and down to find the right spot for you, but I would love to be able to also adjust it to make it feel even more pronounced. The arm rests are great; they are super adjustable and have a comfortable padding.

Great product

I received my chair, I was updated as to the delivery and came already put together. Love my purchase.

Sojo office chair with 4D arms

This is very good chair, it has many adjustments and is very comfortable.
I have not yet received my warranty, and I do have one problem with it - the casters are very stiff and do not roll well. This makes it difficult to move my chair back and forth away from the desk.
