Maxi Mounds is an American nude model, stripper and pornographic actress from Long Island, New York. Mounds is known for her extremely large breast implants. Mounds’ implants are polypropylene string breast implants, which irritate the breast tissue, causing them to grow continuously as they fill with fluid. Mounds’ breasts each weigh twenty pounds. Mounds is comparatively tall for a pornographic entertainer, standing at over 6 feet (1.82 meter) in height.

Mounds holds the Guinness World Record for the “World’s Largest Augmented Breasts”. She approached Guinness in August 2003, but the category did not yet exist. After creating the category, Guinness contacted her to request documentation of her measurements. She was presented with an official certificate that reads:

Mounds (USA) was measured at Sarasota, Florida, on 4 February 2005 and found to have an under breast measurement of 91.44 cm (36 in) and an around chest-over-nipple measurement of 153.67 cm (60.5 in). She currently wears a US size 61MMM bra.
