Best Chair!

My lower back and hips havebeen in pain since I've started working from home during this pandemic. This chair has changed that. In only a week, the pain is subsiding. The Soji is so comfortable, I no longer feel pain while working and no longer think about the chair because it's perfect! I can now focus on my work, because I'm so comfortable. :)

Best office chair I've used

With working from home now the new normal, I wanted to invest in a high-quality office chair that would be a step up from the more standard chairs I've used in the past but would offer the ergonomic benefits that my back, hips, and legs so desperately needed. The Soji has been a god-send for my hip pain. The range of adjustability is unmatched. The 4-D arm rests are generous and have the perfect surface area, are beveled along the perimeter so they don't dig into your arms, and the range of motion is incredible. The range on the back tilt and height adjustment is equally impressive. Haworth did a great job designing an aesthetically-pleasing chair with a beautiful range of colours and fabrics to choose from, comes fully-assembled, has very easy-to-use adjustments, and as a bonus, works well for more petite people. The cushioned seat was more firm than expected but after a day, it was something I completely forgot about.

Great chair at great price

I've owned more than one good office chair in my career including a couple that were $1200+ that were less comfortable, and less good looking. The arms are great and allow me to be and look more relaxed now on meetings because I can put my arms down and lean back instead of reading them on my desk. Have already recommended this chair to two people.

Best way to sit all day

I have tried EVERY chair. Every ball. Every stool. Every way you can sit at a desk, I've tried it. They all hurt my back except for this chair. Worth every penny.
