If you are lucky enough to have the space for a vanity, then you already know that the height of the seat you use is important. Vanities tend to be low, and so should the chair or stool you will be using. You don’t want to be crouching down to see yourself in the mirror. The chair should be comfortable – a padded seat is a plus – and of course, it should look nice, ideally matching the overall style of the room.
An example I find very nice, in two colors:

Since vanities themselves tend to be styled elegantly, it makes sense to get chair that also has that same elegance. Most vanity chairs and stools tend to be more ornate than their regular counterparts. Odds are you will not find something that will match the exact style of your vanity, but try to find something with similar lines. If your vanity is rounded for example, you might want to get a vanity chair that features round lines. Of course you can also go for a contrast in styles, but this is something that doesn’t always work. You can also try and match the color, or once again go for a contrast.
