The chairs have small plastic end caps on the bottom to allow it to slide on smooth surfaces. I ordered 4 and 2 of them had broken end caps. I called the number for the manufacturer and it was an automated message saying to email them. I emailed them and they said to contact wayfair. I called Birch lane and they put in an order for replacement end caps. Now the manufacturer said they wont provide them, so I am getting a replacement stool. Don't purchase unless you are okay with having to figure out a more permanent solution when your plastic end caps break. They look nice, but wobble a little from these pieces.
