Hey, Lucy from Ottuni here. I also help run r/Ottuni.
If you're comparing ergonomic office chairs on Amazon, I wanted to share a few details about the Arix, especially the measurements and adjustments worth checking before ordering.
The Arix has a breathable mesh back with a padded foam seat instead of an all-mesh design. It also comes with adjustable lumbar support, an adjustable headrest and armrests, and a backrest that reclines up to 125° with four lockable positions.
A few measurements worth checking:
- Seat height: 18.1–21.1 inches
- Seat width: 19.9 inches
- Seat depth: 17.3 inches
- Lumbar height adjustment: 40 mm
- Available colors: Black and white
One thing I'd suggest is measuring the clearance under your desk before ordering, especially if you like sliding your chair all the way in. Seat height alone doesn't tell you whether the armrests will fit underneath.

Questions about the Arix or the discount?
If you're thinking about getting one, let me know in the comments whether you're interested in black or white. I'll reply with the discount details and how to get the code.
And if you're wondering whether the chair will fit your height, desk, or home office setup, feel free to ask. I'll do my best to answer with actual measurements rather than just telling you it'll fit everyone.
Happy to keep the answers here so anyone else comparing office chairs can find them too.
