Query: Not strong enough

This frame seemed like a good thing for about one week and then it broke. One of the connections between a leg, supports, and a strap under the mattress snapped off, and it is impossible to fix. The person using the mattress does not weigh over 300 pounds, the supposed weight limit of the frame. This is not a sturdy object.
