This product is a snug fit, easy to install and so far i have used it for 30 days. These fit my square-legged chairs perfectly. My bed is a platform bed with 3 types of feet or supports, rectangular, square and round.

Have protected our wood floors from barstool scratches. Sliding chairs are quiet now. You don't here that scratch when you pull a chair out.

The plastic that the chair leg fits into is yellow colored. Would come off every time chair is lifted or moved. Had to super glue to the bottom of my chair.

Can't tell durability because iam planing on returning them. The covers trap crumbs and small bits underneath and a small movement of the chair causes scratches. They are also very ugly.
