I can’t give an excellent result as the chair was the most uncomfortable chair I have ever sat in. The massage mechanism is like Rocks. For me this is a particular problem as I have an abnormal spine. But I imagine most people would find it uncomfortable. A cushion with a wipe clean cover would help a lot. But in the long term this chair should be replaced.
For the benefit of the beautician the feet should be a a height where she doesn’t ha to bend. Imagine cutting hair using a low chair!
