I'd say, "No thanks." to the Quickie Q7, especially if the other option is a titanium frame TiLite. The TiLite will, more than likely, be a higher quality chair. Their ordering process includes a 'sign off' of the final dimensions presented as a CAD drawing. This is an extra step that greatly reduces the chances of error, and is a HUGE selling point IMO. Don't be afraid to insist on this sign off!!
