The users love Back App

I have a backapp chair in my clinic and recommend out to many patients with lower back,neck problems as well as headaches and stiff shoulders. Its a great chair to help with improving posture and more people should be using them. I would happily recommend patients to Mike as I know he will give great customer service and is very knowledgeable and professional.

Gillian Brown, Clinic Manager

Mike was straightforwardly helpful in getting me the opportunity to try out the Back App, and I like the product, well thought out, aesthetic design and high quality finish.

Charles Dean, Owner, Stroke Rehabilitation Ltd

Received a BackApp Chair as a prize from winnning a competition during the IEHF WEP conference in London. Thoroughly impressed with the chair and how helpful Mike was in the assembly but also the de-assemble of the chair for easy moving of it. Will hopefully be in contact soon with Mike again.

Dr. Freddy Johnsen invented
the Back App chair and got a healthy back!

After years of back problems from sitting on standard ergonomic office chairs with backrests and armrests I had to endure several back operations. After the second surgery I hit upon the idea of the Back App; a new way of making an ergonomic chair.

Now I use the Back App as the only office chair in my daily work. The exercise from sitting on the Back App has changed my life. It is part of my daily exercise to take care of my back. I am healthy again and can sit at my desk with no problems.

From scientific studies it is evident that the Back App ergonomic office chair has the potential to remove back problems. For me it was the most important part of getting rid of back problems. The scientists confirm the experience of thousands of Back App users; sitting on the Back App gets rid of back pains.
