Furniture Wheel Caster Cups/Floor Protectors, Silicone Non-Slip Caster Cups, 1.75x1.75 (4PACK, Black)

I wasn’t sure about the size, as they looked too small for the big wheels on our bed, but after thoroughly cleaning the floor area and getting them under the wheels, my bed no longer moves when my husband and I lean up against the headboard, as the bed isn’t attached to the headboard. We’re very happy with them.

Does the job. Cant complain for price point. Would buy again if needed

small area for wheel, but they havent moved on floor so doing what they are supposed to for tiny wheels...

I have a rolling laundry cart that is between my dryer and hanging Ironing board. Although the wheels lock on the laundry cart, the cart still slides. I got these to sit the cart wheels in and they work perfectly. The laundry cart doesn't move and I don't have to worry about it slamming into my new dryer and scratching or denting the side.

These are by far the best non-slip caster cups I've seen! The design is unique in that they have a recessed opening that is shaped just like the wheels and keeps wheels firmly in place. They also come with inserts that will fill in the wheel 'well' so that it makes the surface flat, which is perfect if you need to stack two of them to level whatever it is you're putting in them. This worked perfect for me because our garage floor is sloped from the house to the outside and I wanted to put a dehumidifier along the back wall. It was leaning forward a lot because the slope is even more exaggerated right next to the wall and the unit would roll forward. I used two of these on each of the front wheels; one with the insert and the other with it removed to hold the caster. After that it sits perfectly level and will not roll or move.These are high-quality and they have a nice, 'gummy' texture, which helps keep them in place.I highly recommend these and will be buying more myself because they are superior to anything I've seen.
