FAQs.

Don't see the answer to your question?

Is ErgoChair Ultra 2 good for lower back pain?
Instead of a separate cushion you slide up and down, the X-shaped lumbar support is woven directly into the backrest structure. It pushes back where your lower spine needs it most while leaving your shoulders completely free, so your posture stays natural rather than forced into one stiff position over a long day.
Does the mesh back keep you cool during long sitting sessions?
Yes. The Air Mesh used on ErgoChair Ultra 2 is 3 to 5 times more breathable than standard mesh, which means heat and moisture move out instead of building up behind you. After a full workday you'll notice the difference — your back stays dry rather than that uncomfortable clammy feeling you get with denser materials.
What makes the seat cushion on ErgoChair Ultra 2 different from other office chairs?
Most office chairs use a single foam layer that compresses unevenly over time. ErgoChair Ultra 2 uses a 4-layer system — breathable mesh on top, memory foam, TPE, and a spring matrix underneath with 62 nodes and 186 struts. The result is pressure distributed evenly across your seat bones instead of concentrating in the spots that get sore first.
How does the adaptive backrest work?
The backrest has flexible ribs built into the frame instead of a rigid panel. When you shift forward to type or lean back to think, the ribs flex with you and keep the surface aligned with your spine's curve throughout the movement. You stop fighting the chair and it just follows you.
Is ErgoChair Ultra 2 suitable for tall or larger people?
Yes. The seat height goes from 18 to 23 inches, seat depth adjusts from 18 to 20.5 inches, and the chair supports up to 320 lbs. If you add the headrest, total height reaches 58 inches — enough to properly support a taller spine without the headrest ending up awkwardly at shoulder level.
How many adjustments does ErgoChair Ultra 2 have?
You can adjust the headrest position, armrest height (7 to 11 inches), back tilt angle and tension up to 25 degrees, seat height, and seat depth. Each adjustment targets a specific point where bodies differ from each other, so the chair fits your proportions rather than approximating them.
Does ErgoChair Ultra 2 come with a headrest?
It's available with or without. If you regularly feel tension in your neck or upper shoulders during calls or long focus sessions, the headrest gives those muscles somewhere to rest without pushing your head forward at an angle. If you tend to sit upright and move around a lot, the no-headrest version keeps things cleaner.
Is it worth upgrading from ErgoChair Pro to Ultra 2?
Yes, if you sit more than 6 hours a day. The Pro is a solid chair, but the Ultra 2's adaptive backrest flexes differently and the 4-layer seat handles extended sitting noticeably better. People who switched consistently mention their back feels better at the end of the day — which is exactly what an upgrade should deliver.
What colors does ErgoChair Ultra 2 come in?
Onyx Black and Dover Gray. Both use the same Air Mesh material and frame construction — the choice is purely aesthetic depending on your workspace setup.
What is the weight capacity of ErgoChair Ultra 2?
320 lbs. That's higher than most chairs in this price range, and combined with the seat depth adjustment, it makes ErgoChair Ultra 2 one of the more accommodating options for people who've struggled to find a chair that actually fits their build.

Meet ErgoChair Ultra 2: Engineered for Movement and Mastery

Most office chairs are built to keep you still. The ErgoChair Ultra 2 is built to keep you moving—gently, naturally, and intelligently. This is the ergonomic desk chair designed for Canadians who work long hours, think hard, and need their seat to do more than just support. With adaptive back support, invisible lumbar guidance, and breathable materials, it helps you move better and feel better all day.

Your Back Moves—So Should Your Chair

Inspired by the biomechanics of the spine, the ErgoChair Ultra 2 adapts to the shape and movement of your body—not the other way around. The flexible ribbed backrest mimics the flow of your spine, offering support while you reach, shift, lean, or rest. The lumbar area is reinforced with an X-frame support system that responds to posture changes while remaining nearly invisible to the eye. No bulky padding, no stiffness—just a chair that knows how you move.

Designed for All-Day Sessions in Any Season

The 4-layer seat uses the same comfort logic found in performance cycling saddles—combining breathable mesh, foam, TPE, and a responsive spring matrix. It evenly distributes weight and pressure, even when sitting for long stretches. Combined with Air Mesh technology that's up to 5x more breathable than standard mesh, you’ll stay cool and focused whether it’s a long call or a marathon editing session. With fully adjustable headrest, armrests, seat height, and back tension, the Ultra 2 makes fine-tuning effortless. Whether you're a developer, designer, or creative multitasker, it gives you intuitive control over how you sit, shift, and focus.
