3X3 Square Rubber Furniture Caster Cups, TL-JIYPU Caster Cups with Anti-Sliding Floor Grip 4 PCS, Ideal Furniture Coasters, Floor Protectors Brown, Non Skid Furniture Pads, Rubber Furniture Cups

They definitely serve their purpose and don't slip. Nice, thick rubber.

These square, rubber furniture casters do exactly what you expect: they keep furniture legs off the floor; and in my case, help keep the furniture from sliding across the tile floor.

I have two twin beds on casters on a hardwood floor, they don't have locking wheels and roll easily. So I got these furniture cups to hold the two outermost wheels on each as they're both up against a wall. Working great on hardwood floor without slipping. Good purchase.

I did not and do not have an issue with the product. It seems to be working as planned. The issue I have with the whole purchase is the delivery. The delivery was three days longer than marketed. This has been an issue over the past 3 months, not to mention the delivery delays during COVID. If it is going to take a week for delivery, say so. Therefore, I can make an informed decision.

Still rolled

These are just what we needed. We just installed new wood floors, and our couch was slipping all over the place. We put these under the legs, and now it doesn't move!

Bed still moves

Works great
