Review on 64PCS Clear Cabinet Door Bumpers Pads For Sound Dampening, Cabinets, Drawers, And Picture Frames - Adhesive Rubber Silicone Pads by Glen Elevyn

For the price, these are hard to beat. They are not "squishy" but soft enough to not damage anything that hits them. They are also strong enough to suspend something up by about 1/3 of an inch. I used some to prevent doorknobs from hitting walls, but I also used a couple to make a "platform" desk on top of my desk that my monitor goes on top of. I can slide papers and some thin items, underneath and my monitor is now at the right height. I'm not sure how much weight they can "hold" but my gut says it's a LOT.They feel really nice to the touch, definitely not cheap, and the adhesive seems incredibly tacky in an interesting way. It feels like you can stick and reposition them a few times as long as you don't press down too hard, but once you figure out exactly where it should be, press down hard and after a couple of hours they will be REALLY stuck there.
