While I am usually pretty skeptical about trading advice; I do not know why but for some reason that phantom thing about the rocker slider stayed with me for years. It just resonated in me. But I was too practical (stuipid) to spend the money on a good chair.
Then when I got married and my wife got pregnant she said she wanted to spend money on a good rocker with a ottoman. Man was I fired up when she came home with an "overpriced" rockerslider used by all the moms. Ever since she stopped breast feeding our second child the chair has been right here in front of my home computer with two monitors. I find myself wanting to stay and trade from home even though I have a better computer setup at work. Part of the reason I like to stay home is the rocker slider. Now if you had the ergonomics of the aeron and the rocker slider on the bottom you would have the perfect chair. My rocker slider is wood with some removable cushions. It is very good but it could be better.
