Right on this table with that thread and that sewing machine is where our very talented seamstresses sew your upholstery. The product we use is a synthetic vinyl developed in America by a company called Naugahyde. No matter what color you pick, the Gratz team sits down and machine sews your chosen color to your made to order apparatus. In addition to being easy to clean, the fabric we use  have been proven to be stain-resistant, durable, fire retardant and antimicrobial. It is synthetic leather that is incredibly durable and created to be long-lasting. Our team hand cuts the foam and straps.

The Factory is buzzing with excitement as we work diligently to catch up and get your custom orders out to you as expeditiously as possible. We appreciate your patience and continued support. Gratz is Where Art Meets Science

Springs, Roll back bars and push through bars

The Push Thru Device has a narrow V for the pad of the foot. It's a nice distribution so that you don't have to figure out where your feet goes. The piece has a Mortis and is projected into the frame. Just by taking this extra step makes the bar incredibly strong.

A spring differs from traditional weights in that as it is stretched from its resting position, it exerts an opposing force approximately proportional to its change in length. In other words, the more you stretch a spring, the more opposing force it responds back. In essence, more force is required to overcome that opposition. Spring resistance varies substantially from manufacturer to manufacturer, so describing the estimated spring tension without a specialized tool is almost impossible.

Gratz does not implement color-coded springs.  We physically calibrate them ourselves by taking an 8 LB weighted object and apply it to the springs to observe its strength. We then take it to the pole station and 'scoop' it down until we get the desired measurement.The difference one feels when using Gratz is how the carriage returns to rest. The carriage is not entirely connected to the stopper, which gives the user an additional challenge of bringing the carriage back to its original position.

All made in the USA at our Philadelphia factory. What is your favorite exercise on each of these bars? Please tell us your favorite and why on our Instagram page.


Meet the Grinding Department. Here is Hector Torres, Michael Mitchell, ismael López-Steele and Mike Vanans making the best Pilates apparatus in the world here in the 🇺🇸

The most important factor in our equipment is the frame to maintain stability. The Reformer frame is made from either attractive solid hardwood or metal frames. Our aluminum frame is made up of 60% post-industrial recycled material.

Aluminum is a versatile, lightweight, durable metal. We use this metal over others because it weighs less by volume and naturally non-corrosive. The aluminum forms an oxide layer that naturally guards against various compounds.

The aluminum extrusion we use to make the reformer is about 24 foot long and has a bull nose: a curved surface that prevents cuts when getting on and off a reformer. We cut it with a double Miter Saw and make them simultaneously at a 45 degree cut and then put them together to breathe life into the reformer.

Pipes on the Cadillac and the Studio Wall Unit are special on the Gratz apparatus. It's very strong- we use schedule 40 galvanized pipes so it has a very thick feel. Galvanizing is a process where liquid Zinc is electrostatically put on the surface to prevent rust. We smooth it out but we don't polish it- we leave a 'tooth' so that when you are working on the equipment you have a good grip and have stability. Once the frames are made, they are welded and chased: a process of grinding and profiling the aluminum. All the craftsman at Gratz have been practicing their skills for many years. It is very important that the welder accurately penetrates the aluminum for maximum strength and safety.
