I have already sent in an unsolicited comment to your Customer Service Department last Saturday.  It went something like this:

I am so impressed with the design of this bed frame with the attention to detail that went into the step-by-step step instructions.  I am a mechanical engineer, so I know a little something about design. It really was easy to install.  In addition, I was impressed with the fact that the manufacturer included extra hardware.  Who does that anymore?   This design is the sturdiest design I have ever seen in a bed frame.  If I need another bed frame, I will know exactly which one to purchase!
