I built a stair tread with matching landing set from the size selection available here.  Fantastic print with many colours to blend and animal furs and help from children slipping on wooden stairs.  I have managed to buy two long runners and two 3x3 landing mats and installed them on my multi level stairwell.  I was delighted to add a matching 5-foot-round rug at the landing of the stairs which meets the front door.  It all matches and looks superb!
