Non-Slip Furniture Pads X-PROTEC... vs Screw-On Felt Pads by X-Protecto...

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.

Pre-drill each leg with a 1/8 bit, then screw them on. It takes the longest to apply due to pre-drilling required, but worth the effort. Drill a pilot hole then screw in.

Unless you tap it perfect every time (big or small taps) they bend and are useless. Attempted to replace similar product with previous nail holes and still terrible. Scratches your floor when the felt wears off--which happens pretty quickly.
