Review on B.PRIME Round Non-Slip Rug Underlay Pad: Secure Your Hard Floors with 4-Feet Diameter. Explore Different Size Options! by David Jenkins

To be used under chair mat on hardwood floors. This is a wheeled office chair that leaves small marks on the floor, so I put a chair mat underneath. The carpet moves constantly and therefore needs to be corrected every few days. I needed something that doesn't leave a sticky residue. Cut to fit the carpet layout, easy to cut with scissors. The pad is lightweight and feels like neoprene/rubber foam, made of the same or a similar material as the kitchen drawer liners. anyone to help with the grip. Drawer liners have a denser weave. The pillow is also a large piece that requires you to deal with multiple pieces of drawer liners to get the same coverage. Since the cushion has a cushioning effect, the chair does not roll so easily, so slight resistance is not a problem. After a while you will hardly notice it anymore. The carpet on the chair is still moving. I would say that's 90% less than the number of layers and frequency of layers. In general it works fine.
