My back is happy now!

I was always under impression that Haworth chairs are expensive for no reason! But after buying 4 different chairs I realized I was wrong. I have a Haworth chair at the office but since the beginning of pandemic I have been working from home and I started developing a back pain. Eventually, I decided to purchase a Haworth chair for my home office and my back is so happy now! Make sure to buy a chair that comes with a lumber back support.

We are happy to hear you are enjoying your new Soji chair, Masoud, and that it has made your work day more comfortable!

Great chair

I opted for the Water color. It looks great in person. The chair is supportive with lots of adjustments to make most, if not all, comfortable.

Nice home office chair

This chair arrived fully assembled, and double boxed. Just unpack and it's ready to go. The chair is a nice improvement over my previous home office chair. I like the seating support (foam), and the adjustability in many dimensions. One very nice feature is the thigh support. I can move the seating surface forwards, which then extends much further under my thighs. Also, the beveled armrest cushions are a nice touch. On the downside, the armrest position does not lock in place. The armrests often slide to new positions when I enter or exit the chair. I debated knocking off a star in my overall review just for this issue.

Craig Barnes
Very Happy!

Spent a long time researching chairs to buy. I settled on the Soji mainly because the options/adjustments it had and the price. It was delivered quicker than I expected as well and fully assembled. Great Chair, Great Experience.

Completely solved my back pain

I've been struggling with lower back pain for the past 4 or so years, and nothing that I tried seemed to make a difference. That is, until I decided to buy this chair. Ever since it's arrived I have not had any instances of lower back pain and it has been such a relief. This chair is worth every single penny that I spent on it and I would highly recommend you give it a shot if you are experiencing back pain from sitting in a poor chair.

Jan, thank you so much for taking time to submit a review! We're happy to hear the chair has made working more comfortable and helped with your back pain.
