Ok, I also think the table is way overpriced. Obviosuly, none of "us" would ever buy that, even if you disregarded its aesthetics, as it would never play correctly without real cloth.
I also think the lawsuit damages are ridiculous. I'd bet the company can ship him a replacement top, or resurface his existing one, for a tiny fraction of what he is suing for.
I do think the company was negligent after reading the article, and without further information. When you have a product that is so far fetched, and different than the accepted "standard", you have to make sure you make it crystal clear to your dealers, the installers, and the end user, of any particulars that must be followed for this unique design.
Although not on the same level of danger, imagine a car that had the brake and gas pedal reversed. Someone getting into that car, would never expect that, and operate the gas and brake the same way the current "standard" is. If he got in an accident, you can be sure everyone from the dealer to the manufacturer would be sued for millions. I see this as a similar situation (although not nearly to the same danger severity).
I believe (but not certain) there is precedence in lawsuits that show the designer of a product when the product is much different than the standard, has the duty to inform clearly the people further down the line from him of the differences and special provisions.
