All absolutely wonderful: This is a solid chair strong lower back support good arm rests with changeable positions moves around well while swiveling and moving across the floor quiet during movement allows me to lean far! back with stability raises up and down well. I love the mesh seat and back as I get very warm on fabric covering. One item doesn't work the head/neck rest which has 3 positions it's in a funky position I can't use it. ***** But I love it!
