According to the manufacturer, "the
user weight limit is meant more to protect the user than the product. A
person cannot make this product burst. That being said - the user weight
limit is meant to keep overweight / deconditioned people off of the product.
It's not a good idea for an obese person to get off the couch and start bouncing
on an unstable surface."
