Query: Not the best example of this type of product

These are not ideal for wood floors. I recommend the type that look like muppets - they are much easier to get under the furniture and glide better.After moving three pieces of furniture, these sliders look four years old - scratched, dirty and indented from the weight. The white lip is curved up slightly, which makes it hard to slip under, and harder for me to do solo - and I'm no weakling.I think there are better examples of this product, especially the furry ones that I got at Home Depot for our house in NJ.
