I purchased crate bed covers a little over ten years ago. They finally wore out and my new dogs were able to chew through them. Positive note on the new covers (ordered two). I like the move of the Velcro from the ,idle of the cover to the side. Much easier to load the foam and cover with the new location. Also the addition of the rubberized no skid surface on the bottom is a nice touch and in the positive direction, negative note - large and x-large are bigger than they were ten years ago. So big that neither one is tight ion the foam and cover. Dogs immediately started chewing on the covers slack material. I removed them from their crates. I also ordered the elevated bed. The stitching finally gave out after ten years. The new elevated cot seems to have better stiching. Otherwise, excellent cot. I like the quality of the new covers, just disappointed they are bigger than the size I previously have purchased. Measured the old covers to get the size I ordered. Thanks.
