Stair Tread (Set of 15)

Package 15 dark grey carpet tread pieces sized 22 X 70 cm in one set to complete surface coverage of standard indoor stair structures and add soft quiet surface layer for hard original stair materials. Utilize self-adhesive backing material to form stable bonding force on clean and dry stair planes, and actual bonding effect is affected by stair surface cleanliness, dust and ambient humidity conditions. Modify carpet surface texture to improve barefoot comfort and weaken noise volume generated by daily frequent up and down stair movements inside residential spaces. Allow partial trimming on mat edges to adapt narrow stair sizes and personalized layout requirements after finishing basic laying placement work on stair surfaces. Spread folded mats on flat ground for a period to eliminate packing creases before formal laying installation to maintain neat planar shape in subsequent long-term usage.
