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.
I have hardwood floors and the furniture always moves. Needed help to get them under the runners though. My sectional stays in place, wish i had bought sooner.
These smell strongly of chemicals which will transfer to your hands when you touch them. Cannot be used in the house.
