Amazing Service

The whole process was seamless and delivery was so quick. I have to give a shout out to Sheryl in the Toronto showroom. She was beyond patient with my indecisiveness and many questions. Although I was buying only one chair, she treated me with above and beyond service. This was not the case with the several other companies I visited beforehand.

I love my new chair! The soji water is absolutely beautiful in my wfh environment and does not look like a big black clunky office chair. The only feature I can’t seem to figure out is the pivot on the 4D arms. I did revisit the showroom and understand that you just need to grasp the armrest, but mine don’t seem to budge. I don’t want to force it too much and break anything. All other features seem in good working order!

Great Quality

I didn't know how uncomfortable I was until I purchased this chair. Thank you for the quality cushion and backrest.

Hi Freda! Thank you so much for the feedback! We are happy to hear that your Soji chair is working out so well for you!

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.
