Same chair everyone sales

I ordered a masterclass chair and an Autonomous chair ergo pro, one week apart. They are almost exactly the same chair, with very minor details being the difference.
Initial impressions are good, time will tell if the materials are of quality.
The cushion starts feeling hard after an hour or so.
They advertise a light gray chair but the one they ship is black (I'm glad i knew about this pre purchase, less of a shock).
It was cheeper than the other copy cats of this chair, my advice is find the cheepest one. The autonomous has better colors.

The chair arrived promptly and was easy to assemble. Very good design for reasonable cost.

Very happy with the unit

Quick delivery to Victoria. Assembly went very well, other than a missing step re the wheels at the very beginning. MasterForm’s prompt support response guided me through that remedy.

Overall, very comfortable. Lumbar support is excellent. I was hoping for better neck support, but an airline-style pillow worn with the chair’s built-in neck support accomplishes that.

Very happy with my new chair purchase

My chair arrived exactly as described, and I found it easy to assemble with the provided instructions and tool. The chair appears to be well made with quality materials, and I find the numerous adjustments very helpful to relieve my chronic back pain. I am very pleased with my chair.
