3 1/2 inch

I purchased both types. 1 set for carpet/ 1 set for flooring. They Really Work, FANTASTICALLY!!! My largest cabinet, put them under all 4 corners, and slid it a across the carpet using 2 fingers! And I am very petite, and injured for life. Im not Very strong, in this regard. Whomever came up w/ this idea, God Bless You!!!! Doesn't scratch the floor/ tear or wrinkle carpets. Super Easy to use. Plastic side down, cusion side up.

These little sliders make moving furniture so much easier on both hardwood and carpeting. They protected my hardwood floors when I had to move a heavy table. They also worked great for a dresser that had to be moved on carpeting. they do stay in place when moving the items

These are perfectly priced and perform equally well! They make moving the heaviest furniture and pieces across carpeted (even thick carpeting) and hard flooring (like ceramic tile) very easy. I've bought 6 sets of them so far with zero issues. The longer the feet of lighter pieces sits on them, the less likely that they'll slide from under the feet because it may take a little time for the foam to conform to the shape of the feet, a day or so. As long as the feet of whatever you put on them measures 3" or less, they'll fit and function perfectly.

Was told I had to get these when moving furniture by myself. I definitely agree! These are super nice to use, and I like that there are so many of them. I use them both on hardwood and carpeted floors with ease. Slides around super easily and can easily push it under any heavy furniture that needs moved. I have moved a lot of furniture around the past month getting my setup solidified. and I will definitely keep these on hand to use in the future! The only thing that would make this a 5-star is if they were a little bigger, they are relatively small

Easy to use. Light weight and did the job perfectly of not scratching our floors

These are fantastic and the price even better! The size of these actually works with almost anything you want to move (I even moved a big set of cabinets worked perfectly) I would say these are a ‘medium’ size - works on small things like a chair and large items- like my big heavy cabinet- they actually don’t have to be the exact size of the legs —- they slid like a dream without making even a mark on my marble floors! (Yea) They have different sliders for hardwood versus carpet so just make sure you are ordering for the type of floor you are using them for…highly recommend! !

I bought a DreamCloud bed with the frame and with everything together it was extremely heavy and a pain in the butt to try and move because my room isn't very big. So moving it away from the wall to change bedding and stuff made it very heavy. Not to mention, the legs on it were scratching my floor. Because my bed was already put together I had a hell of a time getting these under the legs, but once I did I can move my whole bed like it was as light as a feather. Fantastic Buy!

Not the best for tile floors. Works best for carpeting. Good quality though.
