Carpet allows dogs to grip with nails and easy to remove and clean the carpet. Convienent to fold and carry, thus can move to different room to couch or bed or outside, we use on the deck to yard. Eliminated the need to buy multiple ramps.

Dogs heistated at first because a bit narrow. Constructed with a rounded lip to go over to edge of whatever you lean it on and it holds pretty good unless there is nothing to hook into like on a couch cushion. Cannot be placed at an angle because of the lip, both sides need to hook on.
