Can I lean back in it without it feeling stiff?

Yes. The 25-degree tilt range and adjustable tension let the chair move with your weight instead of fighting it. Set the tension light if you like to rock while thinking. Set it firm if you want the chair to hold its position when you lean. Either way the back flexes with you, not against you — the exoskeleton is engineered to move, not to lock.

How do the armrests work?

Four directions: up, down, forward, back, plus inward rotation. Height range 7" to 11." The point of an ergonomic office chair with adjustable arms is that one position carries across tasks. Typing, gaming, calls — set them at elbow-90 on day one, the chair holds that geometry whether you are leaning in or back.

What if I have long legs or short legs?

The seat pan slides 2.5 inches — from 18" to 20.5" deep. That range is what a 6'2" user needs that a 5'6" user does not. Without an office chair with adjustable seat depth, one of them is always perching and the other is always cut off behind the knee. Two fingers of clearance behind the thigh is the target either way.

Will Ultra 2 work for big and tall users?

Yes - up to 320 lbs and roughly 6'4" comfortably. Seat height runs 18" to 23," seat depth slides to 20.5" for longer femurs, and the back is built around an exoskeleton frame instead of a foam pad that compresses under load.

Will ErgoChair Ultra 2 fit my desk?

Most desks are between 25 and 32 inches tall. The seat lifts from 18" to 23." Buy an office chair with adjustable height in that band and a 5'0" user clears a low desk while a 6'4" user clears a 30" surface from the same chair. Feet flat, knees at 90. If your desk is fixed, the chair meets it. If your desk moves too, set the chair once and forget it.

4 out of 5 stars. The ErgoChair Ultra 2 stands out as a super‑comfortable, exoskeleton‑like chair with a breathable mesh back for warmer days. I built mine in just minutes.

4 out of 5 stars. The best-designed office chair. The mesh backrest keeps you cool and you can put this office chair together in five minutes without using any tools.

The best office chair for large frames. Cushioning was comfortable even for my 270 pound frame. Extremely easy to build. Breathable fabric keeps my back cool.

Excellent brand. 4.5 out of 5 stars with over 2500 reviews!

Top quality store. 4.5 out of 5 stars with over 1500 reviews!

Easy to assemble. The seat is very comfortable, more so than the older models that we have.

The adaptive lumbar support and breathable mesh are perfect for long editing and coding sessions.

I'd praise its premium build quality, exceptional adjustability, comfort over long hours, and sleek modern design.

Its adaptive backrest, special lumbar support, and breathable materials make it a strong contender in the mid-range office chair market.

I'm enjoying the chair so far. Feels well made and the quality is pretty damn good!

I love it. Trust me, your back will thank you for this.

I'm pleased. The chair is comfortable and can be configured as needed.

Very sleek. The chair seems to sit a bit straight up / forward, but could be best ergo practice.

It’s fantastic, I love it. Sturdy and comfortable and was SO easy to put together.

I can't say enough about my much better head, neck, and back feel with this headrest. Just want to lay back and fall asleep.

Give this a try! I like the adaptive backrest with flexible ribs, and invisible lumbar support for lower back.

It was worth an upgrade from my last ErgoChair Pro. I love how thoughtfully ErgoChair Ultra 2 understands my back.

750 employees are sitting on ErgoChair Ultra 2 every day.

Replaced my old gaming chair with ErgoChair Ultra 2 to stop destroying my hips and lower back.

Loving the new ErgoChair Ultra 2! Finally found a chair the actually makes my back feel better when I'm setting in it.
