SitFit Chair

Dr. Tzvi Pearlstein practiced orthopedic surgery for 25 years and all that while was on a personal journey to solve the pain he knew since his in utero experience as the child of a Holocaust survivor. His mother's pain became everyman's pain and his search led him to places not normally ventured by physicians. He has created a variety of new inventions, books, and solutions to common problems we all experience.

Sedentary Disease is a global monumentous problem caused by the ubiquitous human Sedentary Lifestyle. The solution to Sedentary Disease is the transformation of the human Sedentary Lifestyle to a non-sedentary or active lifestyle. I have spent seven years developing the first non-sedentary active chair. SitFit Chair is a true total body gym in a portable multi-positional chair.  I plan to develop many versions of SitFit Chair for use everywhere and in all circumstances, i.e. home, yard, school, gym, pool, beach, camping, sports, out-patient rehab, in-patient rehab. Old and young, men and women, athlete and couch potato, those desiring to stay healthy and these seeking to improve their health can all use SitFit Chair. It is for patients fighting cancer, heart disease, obesity, low back and other joint pain, wounded warriors, amputees, hypertension, diabetes, Parkinson's Disease, muscular dystrophy, multiple sclerosis, and many other diseases. 

There is no bigger problem globally and locally than Sedentary Disease. It is often overlooked because we all sit in multiple chairs for various purposes every day. But Sedentary Disease is a collection of epidemic diseases including obesity, low back pain, heart disease, hypertension, diabetes, many cancers, many depressions, and muscle, bone, joint, and tendon ailments of aging.

We sit to eat, work, relax, use our phones, pads, and computers, watch tv and movies, sleep, drive cars, and much more. When we smoke cigarettes, drink alcohol, use drugs, etc, we are aware of our unhealthy habits, but very few people are conscious of the many diseases promoted when we sit in chairs.

Everyone is affected by Sedentary Disease and our Sedentary Lifestyle. The diseases of Sedentary Disease are as ubiquitous as is our Sedentary Lifestyle. 7 years ago I sensed that no one was working on a global solution for one of this planet's and humankind's biggest problems. So I took on the challenge.

SitFit Chair is meant to replace all chairs. Currently all chairs are sedentary. SitFit Chair is non-sedentary and allows for regular healthy exercise while sitting. It is a true total body gym allowing healthy fluid motion through the core, ab crunches from an upright sitting position, low back range of motion and strengthening from an upright sitting position, and a full complement of arm and leg exercises, all with unlimited incrementally adjustable resistance. This total body gym is built into the form of a lightweight portable comfortable inviting affordable upright and reclining multi-positional and multi-functional chair.

SitFit Chair can serve everyone that sits in chairs. That's everyone. For people who ordinarily use gyms, covid has led to gym closures and many people do not want to use equipment used by the masses. Home gym equipment has become very desirable. Devices like Peloton and OYO have been very successful reaching the masses. But no product has yet combined the need to sit for many hours every day in a variety of chairs with the need to escape our Sedentary Lifestyle. SitFit Chair does just that. 

It is for everyone who sits. Moms at home, office workers in office cubicles, kids at their school desks and chairs, collegiate and professional athletes, medically challenged people and use an out-patient "smart" SitFit Chair, and hospitalized patients can use a "smart" in-patient device. The uses are endless.

SitFit Chair is not just for everyone. It goes everywhere. It is carried as a backpack or rolled on wheels.

Every human being sits in chairs for the majority of their day. More time is spent lying down at nite and standing. All time spent not moving is Sedentary. We are Sedentary creatures. Our lifestyle is Sedentary and the great preponderance of human disease is Sedentary Disease. Sedentary Disease may well be the #1 killer, #1 cause of pain and suffering, and #1 healthcare cost. It is beatable. SitFit Chair is the 1st line antidote to all of it. It can be the beginning of a much needed revolution to conquer Sedentary Disease and overcome the currently ubiquitous Sedentary Lifestyle.

I was sitting on "L" chairs at the beach with my youngest daughter 7 years ago. We were fooling around and in the process, I fell backwards. Lying on my back with knees pointed skyward we laughed and I recall saying what a genius God is to create such an awesome sky. I stayed in that position looking up for awhile. I felt a great sense of weightlessness in my back and legs. I recalled how I used to lie on the floor and put my legs up onto a couch or bed to do sit-ups. My daughter and I had a good laugh. Over the next several months I though deeply about my experience and came up with the idea for SitFit Chair. I have worked with 5 different engineering and design firms to date and have progressed through 5 different prototypes.

Having worked in medicine and orthopedic surgery, and having a strong drive to minimize unnecessary pain and surgeries, SitFit Chair combines a desire to conquer pain and disease and limit unnecessary surgery. My mother suffered needlessly as a teenager in the Holocaust in Poland. I have had my own share of pain and struggle which I needed to find solutions for. The solutions for my mother, myself, and my patients, ultimately all converge. I have a collection of healthcare solutions to bring to the public. SitFit Chair is a great passion of mine.

As a retired orthopedic surgeon, former competitive tennis player, runner, rollerblader, gym user and more, I come from a place of health and fitness with a zest and passion for life that SitFit Chair offers everyone. I am all about making the most of one's life and health. I am not only a healthcare provider passionate about caring for people, but also I am a teacher looking to elevate the lives of everyone.

SitFit Chair started as an idea. I have used all my own resources working with 5 different engineering firms over 7 years to gradually and progressively transform an idea through 5 different prototype stages to reach its current state of development. The chair has 5 pairs of hinges that are the complex engine of the device allowing for so many functionalities, positions, and exercises. The secret of unlimited incrementally adjustable resistance was also an obstacle to overcome. I have had many naysayers, but perseverance, hope, and dreams along with courage and strength have gotten me where I am. My vision is strong and I will succeed in making it a reality.

My whole life has been about leadership. I led academically, in tennis, and in trumpet from a young age and graduated Princeton University with a BA in Biochemistry. I graduated New York School of Medicine with and MD. I did a 5 year residency at SUNY Downstate in Brooklyn in Orthopedic Surgery. I served the United States Air Force as a Major. I won a Sikorsky Helicopter award for a lifesaving mission. SitFit Chair is but one of a series of creations that I am now launching to the public, all of which are disruptors in that they provide better health care at a cost savings.
