Make sure you read the description of this task chair. It doesn’t have wheels or tilt. It does have up and down adjustment and spins. I knew this before ordering. The chair took about 20 minutes to put together. I did have to have my husband put the backrest on because it takes some muscle to push the padding into the seat to get it to screw in together. This task chair is comfortable and of high quality material. It works out well on a rug under my desk. Looks great too. Love it!
