Read the reviews of O4 wheelchair users below.
“It is fantastic how little strength I need to manoeuvre my O4 wheelchair over difficult surfaces.”
"I not only have a better sitting posture in my O4 wheelchair, but I now also have better support for my entire body. I have meanwhile experienced how important a well-supported and flexible sitting posture is. I could only sit in my other wheelchair for two hours at a time. I can sit in the O4 the entire day with no problem."
"In spite of the fact that the demo model was a bit too small for me, I immediately sat as I wanted to sit and I could ride over various surfaces more easily."
