Does anyone know which mat would work out for a 3rd row trunk? We're planning to leave the 3rd row down most of the time but would need something that folds up or over when we do put the 3rd row up. I thought I saw on one of these posts there was such a mat but can't find it now. We're going to be getting the all weather mats and ideally would like to have it for the trunk as well. Thanks.
