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.
These are so much better than the felt stick-ons that never last. They aren't very noticeable and save our flooring. They stay on our chairs and help the chair to glide easily.
These fit perfectly over our bar stools and dining room table chairs. Our chair legs are a little unusual, like long pointed ovals on the bottom, and they still fit well using the guide.
Product deserves 1 star! They are difficult to install on a square leg. Will be purchasing original brand next time. Literally falling apart after 1 week of use, fast enough to be able to send item back and get a refund.
