This chair is dangerous! The wheel base is positioned so far to the back of the seat the front is unstable. If you lean forward you are going down hard. Also, the massage function is so light it has no massaging functionality. Lastly, the seat cushioning is very poor. You can feel the base connection through the seat. We have had great items from Wayfair but this is not one of them. Definitely not worth the price in my opinion.
