If you have wood floors, you're probably intimately familiar with felt pads. They're easy to apply, serve an important function to keep your floors scratch-free, and unfortunately they never stay on chair legs, at least at my house. It's because of the constant moving around and sliding, I'm sure... but it doesn't make it any less bothersome.
Next time, try this little tip to adhere pads to pieces of furniture that get moved around a bunch:
First, get a bottle of 2-part epoxy. You can find this at regular stores in the glue section, and it has two separate components that when mixed together are super duper ultra-mega strong. Ultra-mega, guys. The stuff I used for this post is Loctite brand, and I found it at my friendly neighborhood grocery store.
I used a disposable plate and a toothpick to mix the two parts together -- once they're mixed you need to move fairly quickly, so do a few chairs at a time and mix the epoxy in small batches.
Next, flip your furniture over and clean the place where the felt pad will go with rubbing alcohol. Let it dry for a moment, then apply some epoxy with the toothpick. Some brands (like Loctite) suggest applying the epoxy to both surfaces, so I also added a bit to the back of the pads.
Then stick the pad on, and make sure the chair stays upside down and relatively level so the pads don't slide off while the epoxy sets up.
It should set up in a few minutes and should be cured within 24 hours. Easy peasy, and this quick tip will help the felt pads stay on the furniture, where they belong.
