Review on DURA GRIP® Non Slip Rubber Furniture Protectors Set by Larry Daniels

I was looking for pads to put under the legs of the sofa to keep the sofa from sliding on the wooden floor. Pretty much every other option has glue to stick them to the furniture, which I didn't want. Also, my sofa legs aren't flat at the bottom, they're rounded, so the flat adhesive pad wouldn't stick to them anyway. I just wanted something rubbery on either side that would hold both the bottom and leg of the couch and be thick enough that the weight of the couch wouldn't just punch through a hole. This product fully meets my requirements. The sofa doesn't slide at all. Just a note, the pads I received do not exactly match the picture on the website. They are dark gray on one side and purple on the other, but not beige. It doesn't seem to matter which side is up/down.
