So far all is ok. Haven't had the chance to make a full day's use of it to determine whether this was a good purchase or not. But I can tell you that the assembly instructions suck. I've had a lot of experience writing and creating instructions for operators, assemblers and services of highly technical and complex medical equipment and these instructions were almost the worst I have ever seen. It simply shows the follow through commitment of the manufacturer. I hope the chair is much, much, much better than the instructions.
