I am forced to keep a perfect posture. I can work in this chair for 8-10 hours straight with no issues and has really helped me to focus on my tasks. Thank you, ALL33!
Very nice. Loved it from the 1st time I sat in it. Impressed with the quality of the materials and the feel of the chair. Improved my posture immediately.
After 15 years working from home I finally found my perfect office chair.
I am loving this chair and I highly recommend it especially if you are sitting for extended periods of time. Works as advertised and is also aesthetically pleasing. The tan vegan leather is very comfortable and it matched my office furniture perfectly. I choose it over couch and recliner every time!

Great Chair - Finally no lower back pain
I purchased this 2 months ago. I've had lower back pain since sitting in a chair 10 hours a day during Covid. It has alleviated the pain. Great looking too. Highly recommend it.
Probably one of the best online experiences I have had. Great customer service and support! Would HIGHLY recommend!
Back strong chair
This is the second one of these chairs I’ve bought for my husband. One for his office in Florida and one for his office in Massachusetts.
