I love this chair!
Ordering process and delivery was fantastic. The seat is of MUCH higher quality than I was expecting, which makes the price seem more worth it than the regular alternative chairs you find for less than this one. I actually do find the Lumbar extension useful. I was thinking I wouldn't be using it that much, but I have found myself enjoying it. The arm rests are easy to swivel and seem to be very sturdy and useful. This chair feels like it will last quite a while, and I couldn't be happier with it. BTW, this is for the anda seat kaiser 4 v2 chair.
