Converting a Gratz Reformer to Instant Cadillac Conversion: What You Need to Know
Studios often ask whether a Gratz Pilates Reformer can be converted into a Cadillac Conversion, creating a Reformer–Cadillac combination in a single apparatus. The appeal is understandable. A Reformer Cadillac combo can help save space while expanding training options.
While conversion is possible in limited cases, there are important factors to understand before moving forward.
Can You Convert a Gratz Reformer Into a Cadillac Conversion?
A Cadillac Conversion is only compatible with Reformers in Maple Wood. Aluminum Reformers are not eligible due to the construction of the frame and base.
A Cadillac Conversion requires specialized hardware, fittings, and installation methods that cannot be completed by customers at home. Converting an Aluminum Reformer would require industrial machinery and is not supported.
Even with a Designer Reformer, converting an existing apparatus is a complex, professional-level project that involves permanent modifications to the frame.
Why Planning Ahead Matters
From both a studio and manufacturing perspective, retroactive conversions can be challenging. The process often requires taking an apparatus out of service for an extended period while professional modifications are completed.
In many cases, the cost, lead time, and downtime associated with conversion approach those of purchasing a new apparatus, without offering the same long-term flexibility.
For this reason, many studios find that purchasing a Half Cadillac Conversion, a Full Cadillac Conversion, or adding a dedicated Cadillac is the most efficient and reliable solution.
Explore Your Options
Add to your collection
Add a Full Instant or Half Cadillac Conversion, or dedicated Cadillac to your collection. Adding to your studio enhances both efficiency and versatility. With an additional apparatus, you can accommodate more clients at once, expand your teaching options, and create a more seamless training experience.
Replace your current apparatus
Add a Full Instant or Half Cadillac Conversion, or a dedicated Cadillac to your collection and sell off your existing apparatus. Gratz Pilates apparatus is highly sought after and coveted. Many studios are happy to pick up a lovingly used second-hand Gratz Reformers.
Convert an existing Reformer in Maple Wood
This option requires professional installation, specialized tools, and extended lead times. While possible, it should be approached with careful planning.
Important parts needed to convert your existing apparatus into a Cadillac Conversion apparatus
1. A half or full Cadillac canopy including all the springs, roll down bar assembly, belly strap, trapeze bar, sheepskin hanging loops, and a kuna board.
2. Either a full elevated bed or a half-bed insert to provide the base for Cadillac exercises.
3. Removable Shoulder Blocks, given that a normal reformer has permanent screwed in shoulder blocks.


Installation Process
Attaching the Canopy: The canopy is secured to the Reformer frame using flanges, which are installed with large Philips screws and rivets. A specialty rivet nut gun is required to create a secure and stable connection. Once the vertical bars are in place, the canopy assembly is completed.

Replacing the Shoulder Blocks: Fixed shoulder blocks can be removed with a Philips screwdriver and replaced with Removable Shoulder Blocks. While pre-drilled holes exist for the conversion, older models may require new holes to be drilled for compatibility. The fixed shoulder blocks cannot be reused with the sleeves because they lack the thick metal spike / pin that would slide into the sleeves.

Cost Considerations
Converting your Reformer into a Cadillac Conversion is a significant investment. To help you compare your options, here’s a breakdown of the cost of converting your existing Reformer versus purchasing an Instant Cadillac.
