SoftTouch 2-Pack 4" Square Anti-Dent Carpet Protectors - 5/8" Height Spiked Pads for Deep Pile Carpets - Self-Stick Furniture Savers for Sofas & Heavy Furniture - Clear

I used all 8 squares to hold down the 4x3 ft glass mat that I'm using. It was very easy to peel away the backing and then affix the square to the glass mat. Since putting it on, the glass mat has stayed in place and has not moved an inch on the carpet. Seems like it will last a long time and it does what it was intended to do.

The product is fine. However, the packaging has erroneous information, stating that the 3/8 product is for thicker carpets. As the website states, thicker carpets should use the 5/8 length. Buyers should not be confused by the inaccurate info on the package.

Keep recliner in place. Exactly what I wanted for

Long spikes keep the base of the carpet protector from denting your carpet. The 5/8th measurement (over 1/2" or 19mm) is the actual length of the spikes. All regular carpet protector spikes are 1/4" (just 6mm).These spikes are 3 times longer. The base is 3mm or 1/8th inch thick.Regular carpet protectors put a permanent dent in your carpet, just like your furniture does, because pile carpet is deeper than 1/4" which means regular protectors must utilize the base of the protector to support your furniture.These tall protectors points are the support, saving your carpet from dents. The pattern brushes out with the swipe of your hand when removed. There is no pressure into the carpet from the base of the protector.This product is perfect for bookcases or filing cabinets which don't benefit from a plastic cup-style protector.This product should be the first "hit" when searching carpet protectors with tall or long spikes. They function perfectly!

I bought clear double-sided tape as another review mentioned the adhesive tape doesn’t hold well and is unsightly on a clear mat like I have. The tape I bought holds great and was cheaper than the Gorilla brand.As for the product itself, these squares were easy to break apart and apply to my polycarbonate desk chair mat. Overall, they work far better than velcro or tape on the bottom of the mat, but my mat still moves.I have deep pile carpet so I bought the 5/8” size, which should have been perfect according to my paper clip measurement (my pile is exactly 5/8” deep); however, the spikes themselves (not including the platform part) were 3/4” tall and were far too tall in my deep pile carpet. They held up my chair protector everywhere they were and it sagged between them. In addition, the mat still moved.So, I ground the spikes down to 5/8” and tried again. It now works better than before, but my mat still migrates at least 3” both ways every day.I am going to have to drill holes in my mat and tie it between my desk legs to try to assist the spikes in holding it in place.

Purchased for use other than intended. Left amazingly, beautiful marks upon my buttocks.

These might work well for lighter furniture but after a few weeks under a bed and chest of drawers several fractured apart or the spikes broke free. The self stick was not adequate to keep the chest of drawers stuck to the bottom of the feet. The opening and closing of the drawers caused the legs to work thru the stickum and allowed the heavier furniture to fall off

I love that there work for deep pile carpet. If your furniture has a big wide base, these work great. However, if your furniture’s base/feet is not larger than these, beware. These have sharp corners and if they aren’t completely covered by the furniture, your feet will find those sharp corners and they hurt! It scratched me pretty good to the point of bleeding. I wish these came in a round form.
