Felt Pad Stick On. Floor Proctector

The bigs ones are better, the small ones come off easily.  That may be true of any brand, there's so little surface area.  However, some came off the plastic just sitting in the container I put them in  (they come attached to a thin sheet of plastic to protect the sticky side.)

My laminate floor is slippery, so they may work better with a different floor underneath.

It's always possible to get a bad item that is normally very good.  No manufacturer puts out 100% perfect products, they all have some defective items slip through the check point.

The "felt pad type" will not survive use on a tile floor.  They get caught in the tile grout-lines, and get torn off.  I recommend the solid plastic type for use on tile.

The pad is sticking to the floor, no problem there. However the runner slips off the pad. Not good. lol  So a thumbs up and a thumbs down.

I like these felt pads for general application, but I use the self stick pads for another use. With my Battery operated drill with a dowell inseerted into the ring on the back as a mandrel, they make a nice buffing pad, used with different polishing compound grits for working stones and Jewelry. The can be removed easily and changed out with the different colored compound for buffing or removing tarnish. To each his own as far as what you will use these little pads for in your needs and applications.

Get some foam pads that are used for furniture on hardwood floors. Insert them in the clip to protect any wood surface that they might be used on. I use this for video chatting (HD video on Verizon) with my remote work team. I sit at my desk and am able to keep the phone centered and out of the way while I'm working on my laptop. Holds up well and seems very durable!

This works well for pull-ups and feels sturdy.  However, it is leaving black marks on my white door frame where the pads are in contact with it.

Great invention.  Fits nicely and great solution to problem of chairs scratching hardwood floors.  Just using stick on felt was bothersome....would fall off and/or get fuzzy from area rug.

Stuck one on a painted sheet rock wall.  Next day, I found it on the floor.  Didn't stick very well!

I've had the pads about one month and they do keep the couch from moving.  I have people come into my house and plop on the sofa and before I put down the pads, the couch would slide and move when the people sat on it.  I haven't yet looked to see what the pad might have done to my new hardwood floor but even if there's residue left, I think I will be able to wash it off with soap and water.  I don't think it will damage the floor.  I recommend this product.

I use this at work on a fairly regular basis. I usually spray the surface of the suction pad or attachment surface with either water or alcohol and then apply the suction. It WILL stick very well. However, do not leave it attached for very long (remove and wipe the surface and suction pad) or there will be a rank smell when removed.

These adhesive little pads are just what I needed for my furniture feet and legs to protect my floors

Worked as expected, but the felt covering came off after a few uses. Be prepared to either order more felt strips or wrap it with a soft cloth.

The caster cups fit the rollers under my bed, however my bed frame also has a bar with legs and round feet (without rollers) in the middle. So I also had to get a package of felt sliders for those 2 feet. Then I read a few reviews about the white rubber gasket circle on the bottom of these creating indents/damaging in wood flooring. So I decided to get creative to fix that.

After some thought and measuring I also got the "Slipstick CB885 3-1/2" Large Non-Slip Rubber Floor Surface Protector" and put those those UNDER these Slipstick Bed Roller cups. They literally fit perfectly like they were meant to be that way. I took a pic so you can see the rubber floor protector under these bed roller cups. The color matches too! Now instead of the weight of the entire bed being on a thin ring, it is on the whole flat rubber protector under each leg. Extra non-slip too!

3 stars because Slipstick really should redesign these so that the weight and pressure of the bed isn't on that thin hard gasket ring. If it was flat rubber like the workaround I came up with by adding the extra protector piece underneath, it wouldn't damage wood flooring. I do like the product, just shouldn't have to buy another separate product just to make this one not damage your wood floor. Which is what most people are buying this for in the first place! ><

I really wanted to love this product.  I chose it because I believed it would be more effective than some of the less expensive non slip rug pads, but it is not.  Plus, the pad is hard to lay flat and has resulted in some bunching which is creating lumps under my rug.  Bottom line, if you are looking for padding, go for the felt pads.  If you want non stick, don't waste your money on this pricey product.

Bought these for under couch legs that sits on tile floor. I have used 1" wide 2-sided thin rubber adhesive tape (that can be purchased at auto store or Walmart) to hold them to the legs themselves. They do work great in prevent the couch from moving. I do, however, have to wipe/clean the while rubber rings on the bottom with rubbing alcohol every several months so to keep the friction active.

The pad was well cut, but a little longer than needed.  So I had to cut a small section of one of the short sided.  Easy to do with a heavy duty shear.  I placed the non-slip pad down in place and put the carpet over the pad.  The carpet was about three inches (on all sides) larger than the pad and laid flat on the floor.
