Mattress Bag for Moving/Bulk Trash (Brightwood-Takoma)

Hi,
Does anyone have a plastic bag for a thin full size futon mattress? The kind of bag used for moving is also required for any kind of mattress for DC bulk trash pick up.

We have bulk trash scheduled on Tuesday morning and did not realize our futon mattress has to be placed inside a plastic bag for bulk trash pick up.

Photo is an example.

Thank you.
