They work well on carpet ONLY. But I could slip plastic dinner plates under my furniture and move them on carpet. For heavy furniture, they do not work on any of the hard floors in our house, including tile and cement. For light furniture, they work great...but I DIDN'T NEED THEM FOR LIGHT FURNITURE!

Here is the best part. The instructions:

Instructions for use.
1. Versatile build that accommodates nearly all furniture.
2. Installation that is simply effortless.

Umm, how are these instructions?? I had to go online just to verify which side goes up, having never seen a product like this before up close. LOL

I was very disappointed in this product. My advice is to get a friend to help you lift your heavier furniture. These products and the ones like it simply don’t do what they say in their advertising!!

Can't slide anything on these plastic discs. The size is great, but they do NOT slide like other furniture movers!!! Going Back to MAGIC SLIDERS.

I have some some of these with the plastic base that slides and they are awesome. I use them indoors and outdoors on my deck. These not so much...they immediately slid from under the legs of the furniture. Ended up not using...will probably throw them out.

Extremely disappointed with these movers. Too small to move basic size furniture. I had the original orange moving men which were awesome and lasted YEARS. These are just cheap materials. The sponge does not return to shape, and because they are so small they get stuck in carpet ruts and the furniture falls off the pad. Past my Amazon “return window” but here’s a warning to potential buyers. Look for another product.

These looks like the solution to moving furniture but think again! They don't work worth a darn. Won't stay in place and kept slidding out from under furniture. Tried all types of furniture and weight as we were installing new flooring throughout the house but none worked!

scratched my laminate flooring. Not effective on the carpet, either.

Did not work -did not adhere to the legs of the furniture - slid out from underneath the furniture —I have bought a similar product before ( A different brand —)and it worked much better —this product is not good! I returned them total waste of money
