Love the design and the feel of these treads, they look great in our home. HOWEVER, the point in buying stair treads was to keep from slipping downstairs. The adhesive on these is a JOKE! The treads slid out of place from kneeling on them. I cleaned my stairs per the instructions, but the double sided tape hardly stays on the back of the carpet. At 9 months pregnant, I am MORE concerned about slipping down the stairs AFTER installing these. I give three stars because the look and feel is pleasing enough for me to buy double sided carpet tape to reinforce them.
