Learn how to install the Original Platform Extender on your Pilates reformer. Step-by-step instructions, common mistakes, and compatibility tips for a secure setup.
Quick answer
Installing the Original Platform Extender takes about five minutes. Align the brackets with your reformer frame rails, slide the extender into place, and secure it with the locking pins.
Compatibility check before you start
The Original Platform Extender is designed for select reformer models. Before purchasing, verify that your reformer has compatible frame rails—typically models with a standard-width carriage and rail spacing. If you are unsure, measure the distance between the inner edges of your frame rails and compare it to the extender bracket width listed in the product specifications.
This accessory adds roughly 12 inches of platform length, which is ideal for taller users or exercises that require extra legroom. If your reformer has a shorter frame or non-standard rail spacing, the extender may not fit securely.
Tools and preparation
No specialized tools are required. The extender comes with two brackets and locking pins. Clear the area around the foot end of your reformer so you have room to maneuver. If your reformer has a floor mat, remove it temporarily to access the frame rails.
Installation steps
- Position the brackets: Slide each bracket onto the frame rails at the foot end of your reformer. Make sure the bracket openings face outward so the extender platform can slot in later. Common mistake: Installing brackets upside down. The wider opening should face away from the reformer.
- Insert the locking pins: Push the locking pins through the holes in the brackets and into the frame rail holes. You should hear a click when the pin engages fully. Checkpoint: Give each pin a gentle tug to confirm it is locked. A loose pin can cause the extender to shift during use.
- Attach the platform extender: Align the extender platform with the installed brackets and lower it onto the bracket rails. Slide it forward until the platform locks into place with an audible click. Common mistake: Forcing the platform onto misaligned brackets. If it does not slide easily, remove the platform and recheck bracket alignment.
- Test the connection: Stand on the platform and apply gentle pressure in all directions. The platform should not wobble or shift. If it does, remove the extender and re-seat the brackets. Checkpoint: Perform this test before each use, especially after moving the reformer.
