These just stick on the bottom and gripped my laminate floor like a champ. We have hardwood floors and our modular couch would slide all the time with our dogs jumping on and off.
Did it with a box cutter and worked great. Adhesive is very strong and holds well. Easy to cut to size and very sticky and secure.
These leave a yellow mark on hardwood floors. Simply rub it off with a pink school eraser. They work somewhat; the mat definitely slips less, but it still slips.
They bend a little bit too easy, so make sure you take care when nailing them in. It is critical to pre-drill a hole then hammer them straight on firmly.
We replace the cheap plastic pads from our west elm dining chairs with these nail-in felted pads and it was the best decision ever. No more scratched on the floor. Easy to clean with mild household cleaner.
Save yourself a headache and go with a different product. Useless piece of *. Hard to install.
Hammering too much or too hard causes felt to flatten. The nail is not heavy duty and not fastened well to the pad. Seems as though the nail pokes through the foam when there is someone weighing down the chair.
A good product spoilt by it’s small size. About the size of a thumb tack.
