Don’t buy
This item is a piece of crap. The seat doesnt stay on base firmly, it moves when you move. Feels like it will break in weeks. The cushion is already changing shape after sitting on it twice, it’s not firm enough to support long term use. The rubber on wheels is a hard plastic, it doesn’t buffer any noise.  Cheap material and cheaply made. I wouldn’t buy again, they have a no return policy so beware!
