The chair is good, but man, as 32 year old who is physically fit, its rough on some back spots. I wouldn't recommend it for older individuals. The calf rollers are not impressive, but foot rollers are great. The chair works and is of good quality, but if I was 300 lbs., I would not fit into this chair. Lumbar heat is great. Interface is somewhat user friendly, but I can't seem to find a suitable massage since at its lowest setting the rollers still destroy my back. Sometimes the pressure feels like it is pinching instead. Buyer beware, get another chair.
