Invenho uses a contact-activated, gel-free surface over a plush mat with rubberized nonslip dots. Four dimensions are listed from 20 by 16 to 44 by 32 inches, and the entire mat is described as machine washable and dryable for uncomplicated crate or car care. Small and Large grey variants were orderable when checked, but the page does not quantify the cooling mechanism, two other grey sizes were unavailable, and only eight public ratings support the product.
