Its a great chair.  I would recommend that anyone with chronically tight back muscles  place a blanket over the rollers as some of the styles are a little much.  The neck massage worked really well -- I thought but I was hurting so bad next day.. it wasnt the chair.  I found out I have a (healing) upper cervical vertebrae fracture.  Oh the rollers for feet.  Stay away from roller on feet if you have bunions.   Overall a great chair
