Great investment for your back!
Pros: comfortable, but you still get deep tissue massage (if you remove the back padding) or use the padding if you have tender tissue; serves as additional seating in your living room!; quick and easy to use for when you don't have time to go get a massage; great investment - no more spending on $80 one-hr massages; there's enough room and it also reclines.
Cons: the only reason for a 4-star is because it could use a foot rest so that you don't strain your back (a little bit of elevation on my feet completely relaxes my Lower back and hips, allowing for the chair to do a better job). I use my own but have to keep moving it from one place to another as I only have one.
