Open to ideas
i Just reread your comment above and i think you may be misunderstanding the concept. There is NOTHING below the chair
all the lifting is done by 2 support arms which hook under the chairs main handle grips ( at top of machine )
no plate under it at all
thanks

I get there is no plate on your design but just wanted you to think about what happens if the chair touches down prior to the end of travel.

If the mechanism would continue without damage thats great but if it were to continue down damaging what i presume is an expensive chair not so much.

I couldnt see your sketches to see the interface between the machine and chair so you may well have this covered
