Question 1

Which Autonomous office chair should I pick?

Accepted Answer

Pick the Ultra 2 if you shift position all day and want support with nothing to set. Pick the Pro if you would rather tune one position and keep it. The Core covers the basics at the entry price.

Question 2

How do I know which seat height I need?

Accepted Answer

Measure from the floor to the back of your knee with your shoes on. That number is your seat height, and every chair here lists its range so you can match it. Our seat height calculator gives you the same figure from your height if you would rather not measure.

Question 3

Which chair helps most with lower back pain?

Accepted Answer

Fit does more than any single feature. Aim for feet flat, hips level with your knees, and the backrest meeting your lower spine. The Pro lets you set lumbar support to that exact spot, while the Ultra 2 uses a flexible frame that supports your lower back with nothing to adjust.

Question 4

Lumbarless flex-frame or adjustable lumbar, which suits me?

Accepted Answer

They suit different sitters. The Ultra 2 flex-frame bends with you, so it fits someone who never sits still. The Pro lumbar pad locks to one spot, which fits someone who settles into a posture and stays there.

Question 5

How many directions do the armrests move?

Accepted Answer

Three on the ErgoChair Pro: up and down, forward and backward, left and right. The Ultra 2 adds a fourth, so the pads also pivot. Both are built to move freely, so you reposition them with one hand rather than a tool.

Question 6

How do I adjust an ergonomic chair to fit me?

Accepted Answer

Set it from the ground up. Seat height first, feet flat with knees level to your hips. Then seat depth, two or three fingers between the seat edge and the back of your knees. Armrests next, then tilt tension. The video walkthrough shows each step in order.

Question 7

How long does an ergonomic office chair last?

Accepted Answer

Every chair is built to 100,000 cycles, with the seat, the tilt mechanism and the gas lift tested together on a rig rather than one part at a time. The frame carries a lifetime warranty on the Ultra 2, Pro and Mesh.

Question 8

Can I fit a taller gas lift?

Accepted Answer

Yes, the ErgoChair Pro takes a third-party gas lift. Match a barometric rod diameter of 50mm and an open length of 270mm. That is the route if you are tall enough to want more height than the stock lift gives you.

Question 9

Can I fit third-party casters for hardwood floors?

Accepted Answer

Yes. The stem size you need is 11mm, so any caster sold with an 11mm stem will fit straight on. Check the stem before ordering, because 10mm and 11mm look identical in a product photo.
