The Official Machine Fit Guide

Cardio displays are totally unpredictable. Sometimes the built-in ledge is right in the middle, and sometimes it's all the way at the bottom of a massive screen. We engineered the CHCK3D Phone Riser in two specific sizes to guarantee perfect, eye-level posture regardless of what machine you use.

Use our master fit guide below to determine exactly which Riser size you need for your gym's equipment.

How Our Sizing Logic Works

If your specific machine is not listed above, you can easily determine your size by looking at the machine's built-in phone tray:

• The Small Riser: Use the Small Riser for standard ledges. Designed for machines where the built-in ledge is located in the middle of the cardio screen.
• The Large Riser: Use the Large Riser for those deep, bulky screens. Designed for tall cardio console screens where the built-in ledge is located at the very bottom.

Does it fit my phone?

Yes. The CHCK3D Phone Riser relies purely on gravity, friction, and clever mechanical geometry. There are NO magnets, NO adhesives, and NO suction cups. It securely holds all phone sizes, including heavy Pro Max models with thick cases.
