Understanding the differences in gas cylinders and mechanisms between Equa 1 and Equa 2 chairs can help you determine which model you own. Once you’ve identified your chair, you can purchase the appropriate replacement cylinder below:

• Equa 1 Cylinder
• Equa 2 Cylinder

Checking the Gas Cylinder

If the cylinder has already been removed, examine the top section:

• Equa 1: Features a small, protruding metal button.
• Equa 2: Has a flush button.

Refer to the graphic below for a visual comparison.

Identifying by the Mechanism

If the cylinder is still attached, the chair’s mechanism provides another way to distinguish between models:

• Equa 1: Has a visible slot at the front where the key holds the cylinder in place.
• Equa 2: Does not have this slot.

Refer to the graphic below for a visual comparison.

Discontinued Version

Does your cylinder have a screw or spring appearance? If so, that is a super-old version, and we don't have replacements for this style.

Here is a photo example of this discontinued version:
