best thing for comfort at work
purchased for my office desk chair - not a very good item and this has made all the difference in the world.<br />raises me up enough that using the keyboard is not painful on my arms.  not too high but just enough.  also much less discomfort after sitting all day - work in customer support and am on the computer and phone all day ... i do get up every hour but still its a lot of sitting.  this helps tremendously.  highly recommend it.
