They work on different sized chair legs.

They fit perfectly and look great.

These work really well on my dinning room table chair, they do not fall off and even thought they are for round bottoms they fit perfect on my rectangle chair bottoms . I will certainly order more today to finish placing them on my other chairs that need covers. Great product!!!

I bought 2 sets of these sliders to do our 4 kitchen chairs. The large size was perfect for our heavy wooden furniture. Now the hardwoods are well protected. Now I need to order 2 more sets to do the bench which has 6 legs. The cheaper sliders just do not work with heavier furniture. Very happy with this purchase!

Work great on my cork floors!
