The woman said she had purchased her elderly mother a new mattress as a surprise and threw out the old one, only to discover that her mother had hidden her life savings inside.
When she went to look for the mattress it had already been taken by garbage men, she said.
The woman searched several desposal sites but failed to recover the mattress.
Yitzhak Borba, the dump manager, said his staff had helped the woman, saying she appeared “totally desperate”.
He said he increased security at the site to deter would-be treasure hunters.
The woman said it could be worse.
“People have to take everything in proportion and thank God for the good and the bad,” she said.
