Anti-slip stair treads
We have a two story house with bare hardwood stair treads. Over the years we have seen two slips and falls on these stairs, no serious injury. Both times the person was walking without holding the handrail and was wearing socks, not shoes. I think bare feet have better traction than most socks.
I am thinking about putting carpet stair treads on each tread. I believe these can be held in place with double sided tape.
I also see on the web that at Lowes, HD. and Walmart these treads run about $15 each. I am a bit surprised they cost that much and wonder if I am even looking at the right item.
