The wooden frame was covered in mouse droppings and had to be cleaned with lysol, however mattress was not affected so I kept the product.  I bought the futon for grandchildren and they love it.  It was difficult to put together, much easier after we through away the instructions.  Mechanism is hard to set back up.  Wouldn't buy again,  only reason I kept it was the mattress is vacuum packed and didn't know how I would send it back.
