Commercial Furniture Buying Tips
The most common chair base is the 4 leg, but different options are available with different benefits.
Sled base

The back and front legs are connected in a sled style. They are useful for sliding back and forwards without catching and are quite common in workspaces and education. They provide good weight distribution so that they don't get stuck on uneven flooring. Also good for outdoor use on surfaces such as grass.
