Excellent Quality and Superior Comfort!
The ergonomic chair truly met my expectations. You can feel the quality from the first time you sit on it. It provides great comfort and support even during long working hours. The back support is excellent, and the materials feel premium. I’m very satisfied and highly recommend it.

So comfortable
This chair is incredibly comfortable and provides excellent support for my back. I spent over 12-13 hours at my computer and never felt any pain. I highly recommend it.

Great chair but interesting set backs
Hello! I love my chair and it’s kind of uncanny how cozy it is. I will say though, it has a slot to install a foot rest and it doesn’t come with one. I got the morph green chair. Also, my chair’s edges towards the front kind of scratch me lightly because of some material poking out. The front mesh. Overall the chair has changed my experience of sitting and I have way more of an easier time working from home. I would like to order a leg rest and be given solutions for the scraping material poking out in the front if possible. Great chair!

FAQ
Good toknow.
Will it fit my height?
The seat adjusts from 18 to 21.8 in high and holds up to 300 lbs. It’s made for people 5'0"–6'3" tall. Compare the seat height with the chair you use now. The full dimensions are in Specifications above. Not sure? Email service@sunaofe.com with your height and desk height, and we’ll help you choose.
Can I try it before I buy?
Yes — at home. Live with it for 60 days, and if it isn’t right, send it back. Returns are free.
How does the Auto-Track lumbar work?
The lumbar support moves with your lower back as you shift, across 3.5″ of travel, so the support stays where your back is.
How fast will it arrive?
In-stock orders leave a US warehouse within 1 business day and arrive in 3–7 business days. Delivery is free across the contiguous US.
Is it hard to put together?
It needs some assembly. Everything you need is in the box, with step-by-step instructions. The full assembly manual (PDF) is in Specifications above.
What does the warranty cover?
Chairs, desk frames, motors and controls, and monitor arms are covered for 5 years; desktop surfaces for 2 years. Coverage includes mechanical parts and structural defects.
Is there a discount for buying several?
Yes. Orders of 10 or more get volume pricing. Tell us what you need and our business team will send a quote within one business day.
Can I change or cancel my order?
Yes, within 2 hours of ordering. Email service@sunaofe.com and we’ll take care of it before it ships.
