Using them for holding chair and table down for sim racing, keeps them both locked down and sturdy.

These are simple and cheap and get the job done. I don't know how they could be better or you could ask for more. They're hard rubber and will support a lot of weight and keep it in place. The machine I'm locking down is literally a half ton device that moves and shakes so much that nothing could keep it in place on the floor. Inevitably, it would always migrate in one direction or another. It was getting to the point that I was seriously considering just removing the casters -- but we sometimes need to move the machine a long distance and the casters are necessary then. Installation couldn't have been easier. I used a floor jack to get the machine off the ground and then lowered it onto the rubber pads. I was pretty careful about making sure to line the wheels up with the indentation and get them centered, but I found it wasn't really necessary. Even just two of the pads locked the machine down to the point where we couldn't move it but it came with four so I went ahead and used all four. It's been two months now and the machine hasn't moved an inch. Everything else I looked at was dependent on matching the size of the wheels with the pad or would have allowed some movement in some scenarios. These are perfect, I would have paid many times more for them.

I was hesitant to purchase only because I didn't think they would work. I have a 50 gallon container that I made out of a litter box, I bought a platform with wheels so it would be easier to clean under and around it. The plate form I bought didn't have lock on the wheels so I had to get something because it would move around when I would clean it. I put these under the wheels and it didn't move at all! I was impressed! These are worth it.

The material that they are made of , binds onto the slippery floor surface and furniture does not slide. The center part of the coaster is depressed which gives furniture legs and wheels an extra strength to stay in place. Great product!!

Thanks

These stoppers do a great job keeping my chair steady with auto racing simulators. I drew outlines on my clear floor mat to remember their placement.

I moved to a place with laminate flooring and found my bed scootching a little when I'd get into it at times due to being on casters (wheels). These have solved the problem. Super easy to just slide under the wheels and hold them in place.

I bought these with the hope them not sliding once put under the wheels. They slide.

I've had these for two years now and they work great. They are under my fridge wheels to help prevent my fridge from sliding out on my wood floor too easily. They keep it in place and even when we do need it to slide out, it slides without scraping all over the wood floor. Highly recommend for what these things do

Bed no longer slides around on the tile floor. These things worked great at keeping the bed from moving all over. Definitely recommend if you’re looking for something to keep the bed from sliding.
