The Pilates Cadillac and Wunda Chair: The Apparatus Beyond the Reformer

Most people meet Pilates through the reformer, the sliding carriage with springs and straps. It is the most versatile piece of equipment in the studio, and for good reason. But the classical method Joseph Pilates built runs on a whole family of apparatus, and two of the most useful sit just beyond the reformer: the Pilates Cadillac and the Wunda Chair. At West Hollywood Pilates, we teach on all of it in private, one-on-one sessions, and knowing what each piece does helps explain why classical Pilates feels so different from a group class on a single machine.

Why Classical Pilates Uses More Than One Machine

Joseph Pilates did not design a single machine. He built a system, an interlocking set of apparatus that each teach the body something the others cannot. He called the method Contrology, the art of control, and control is easier to find on some equipment than others for any given person on any given day. The reformer scales resistance smoothly, and the mat strips everything back to your own bodyweight. The Cadillac and the Wunda Chair each add a specific kind of challenge and support that rounds out the work. In our classical training, the reformer and mat are the heart of a session, and the other apparatus sweeten it, chosen for what your body needs that day.

The Pilates Cadillac, or Trapeze Table

The Cadillac is the tall, bed-like frame with a canopy of bars and springs overhead. It is sometimes called the Trapeze Table, and if you have only ever seen reformers, it can look intimidating. In practice it is one of the most supportive pieces in the studio.

The overhead springs let us assist a movement as much as challenge it. A push-through bar, for instance, helps the spine articulate one vertebra at a time, which is very hard to feel on your own. Springs attached at the legs or arms can teach the hips to move while the core stays quiet, or open a tight shoulder girdle without letting the ribs pop forward. Because the frame is stable and the springs can lighten a movement rather than only load it, the Cadillac is where we often take spinal mobility, shoulder work, and controlled stretching that would be too much unassisted.

It suits a wide range of bodies. Someone rebuilding confidence in their back can work with the springs supporting them, while a strong, experienced client can use those same springs to add real difficulty. The apparatus meets the person, not the other way around.

The Wunda Chair: Small, Quiet, Deceptively Hard

The Wunda Chair is the opposite of the Cadillac in size. It is a compact box with a pedal and springs, small enough to sit in a corner, and it humbles almost everyone. There is nowhere to hide on the chair. With a single pedal and very little to hold onto, your control has to come from your center.

We use the chair for lower-body strength, balance, and the kind of standing and stepping work that carries straight into daily life. Pressing the pedal down and, harder still, controlling its way back up asks the deep muscles to work evenly rather than letting the strong ones take over. It builds the stability you use every time you climb stairs or catch your balance stepping off a curb. Longevity, not spectacle, is the point.

How the Cadillac and Chair Fit Into a Session

You will not meet every apparatus on day one, and you should not. Classical Pilates is progressive. We usually begin with mat and reformer, the two pieces that teach the foundations of breath, centering, and control. As those settle, we bring in the Cadillac and the Wunda Chair to address what your body specifically needs, whether that is more spinal mobility or the lower-body control that years at a desk quietly erode.

The apparatus are not a menu you order from. In a private session, the choice of what to use is a teaching decision, made in real time by watching how you move. If your spine is not articulating well on the mat, the Cadillac's push-through bar can help you find it. If your standing balance is shaky, the chair can build it safely. The reformer, Cadillac, and chair are one connected system, and moving between them is how the work stays fresh and honest over years, not weeks. If you are still getting oriented to the equipment, our guide to what a Pilates reformer is is a good place to start.

Why the Full Apparatus Set Belongs in a Private 1:1 Studio

This is where the private, one-on-one format matters. In a group reformer class, everyone works on the same machine doing roughly the same thing, because one teacher cannot program five different bodies across five apparatus at once. Classical Pilates on the full equipment set asks for a teacher who is watching one person and choosing the next piece of apparatus for that body, adjusting the springs to them in the moment.

At West Hollywood Pilates, every session is strictly private. There are no group classes and no duets. The studio, near Melrose in the West Hollywood area of Los Angeles, is set up so the reformer, Cadillac, chair, and mat are all available within a single session, and your hour is built around what you need rather than around a class plan. That is the difference the apparatus is designed for, and it is part of why classical Pilates has kept people moving well for decades.

Common Questions About the Pilates Cadillac and Chair

What is the difference between the Pilates Cadillac and the reformer?

The reformer is a sliding carriage on springs that you move along a track, offering smoothly scalable resistance. The Cadillac is a fixed frame with overhead springs and bars that assist or challenge a movement from above. The reformer is the most versatile all-around apparatus, while the Cadillac excels at supported spinal articulation, shoulder work, and controlled stretching.

Is the Wunda Chair harder than the reformer?

It can feel that way, because the chair gives you very little to hold onto and asks your center to do the stabilizing. It is not harder in an absolute sense, it simply removes the support that makes some reformer work feel manageable. We introduce it once your foundation is solid.

Do beginners use the Cadillac and Wunda Chair?

Yes, when it fits. Both apparatus scale to the person. A beginner might use the Cadillac's springs for support and the chair for gentle balance work, while a more advanced client uses the same equipment for real load. In a private session, we choose the apparatus and the spring setting for where you are.

Can I try the Cadillac and chair in a first session?

Most first sessions focus on mat and reformer so we can assess how you move and teach the foundations. The Cadillac and chair usually come in once those basics are in place, though we tailor every session to the individual.

If you are curious what the full classical apparatus set feels like when a session is built entirely around you, the best next step is a private intro session, where one teacher builds the hour around how your body actually moves.
