K & H cots are used, among others, at the 3 week board and train that our almost 3-year-old Norwich terrier recently completed.  The trainer recommended K & H the highest out of many available online.  It's very well-made, sturdy, easy to assemble, clean, and take apart for travel. It's remarkable how it fits into the "place" command that has helped our pooch so much with impulse control and relaxation.  He's snoring in the sunshine right now on his K & H cot after his breakfast. :-)
