Anti slip stair tread, in my opinion, should be mandatory for every house with stairs. Especially if children reside in the home. They always get in a hurry and can easily fall. The same applies to the elderly (except for the hurry part). Non slip stair treads are available in rubber, metal or vinyl. Choice is depicted upon your needs. Go to:
