I was disappointed with this Stool, the castors are not of good quality, they do not glide on the floor effortlessly as they should. I have another stool and a chair with castors and they glide along the floor with ease.  This stool would be 100% better if it had better castors.
**** Update -- after further inspection, the issue was that one of the castors was damaged at the edge and would not allow stool to glide easily. I have requested a replacement castor (free of charge), I hope that once this is received it will solve the issue. Ordering the damaged part replacement on-line was easy.
