NEW YORK -  A 320-foot long pine wood picnic table set the Guinness World Record. Built to honor the Hellman's Mayonnaise centennial, it weighs more than 8,000 lbs. and seats 450 people.

The World's Longest Picnic Table, blocks from Richard Hellmann's original deli where the mayonnaise originated, was the setting for a burger meal for 500 diners along with celebrities Chef Mario Batali (he created the menu), Chef Tim Love, Chef Aaron Sanchez and guests Katie Holmes, Andy Cohen and Paul Pierce of the Brooklyn Nets.

A Guinness World Records official made the official measurement that sets the pine table into its record book. Technically it's 320 feet and two inches.

Constructed from solid, pine wood, and longer than a football field, the table was disassembled and all useable wood donated to Build It Green, which will recycle the lumber along with other building products it sells for reuse for projects in New York City.

Hellman's Mayonnaise traces its roots to Richard Hellmann, who opened his delicatessen in New York City in 1905. His wife' recipe for mayonnaise was featured in salads and sold in the deli, and the condiment became so popular that Hellmann began selling it in "wooden boats" that were used at the time for weighing butter.

While Guinness confirms at its site that the Hellman's pine table set the world's record, Safeway Inc. achieved a similar feet in 2011, building a Douglas fir table exceeding 305 feet to celebrate the launch of its Open Nature food line.

In keeping with that brand's all-natural ingredients approach, the record-setting table was to be built with only Forest Stewardship Council (FSC) certified Douglas fir. For every FSC Certified tree used, 10 more were to be planted.

The 2011 Safeway table was 305 feet long, equivalent to 38 standard picnic tables. A total 7,176 feet of FSC Certified Douglas Fir wood and 1,032 bolts were used to construct that table, built by four people over 10 days and weighing more than 11,304 lbs. Seating 405, the table broke the previous Guinness World Record (248 feet, 2 inches) set in New Orleans in October 2009.
