Studio-grade reformers, built by the people who teach on them every day.
So we stopped settling for the same taupe machine every studio owns, and built one worth being seen with — proven every day across our own studios, and unmistakably its own.

Every reformer in the category hides behind the same soft neutral. Jack Knife owns a single bold vinyl — deep, warm rust — on a natural maple frame. The wood is the stage; the colour is the brand.
It's the one thing you'll recognise across a room, in a feed, in a studio full of ghosts. Not a better machine. A famous one.
One machine, four vinyls. Rust leads; oxblood, forest and cream are custom options for the ones who want theirs. A short, considered menu — never a rainbow.






One reformer, one line, an endlessly re-skinnable canvas. That's how a colour becomes a brand.


A plush, deep-pile rug made to live under the reformer — floor protection, sound and grounding, dressed as a design object. Mix any rug with any machine. Finished with an oxblood-leather JK tag.




Don't love it? We'll come and take it back. No boxes, no fuss — we can say that because we teach on ours every day.
If a Jack Knife ever fails you, we replace it. This is studio-grade equipment, made to be used hard, daily, for years.
Most reformer sellers are distributors who've never taught a class. We run studios. We build the machine we wanted to teach on.
Choose your colour and frame, add The Stage, and make it yours. Studio-grade, guaranteed for life, delivered to your door.
