Wide Slatted Footrest
Product Review (submitted on June 5, 2011):
It is unbelievable how much pressure can be relieved from your lower back by such a simple device. Everyone should have one of these at their computer station, regardless of back pain. I suffer from unbearable back pain, and this device has enabled me to sit comfortably for FAR longer than I ever could. I'm going to get another one of these tomorrow for the office.
I recommend this wider model, which provides more much-needed surface area for your feet.
If you have back pain, or want your back to last, I HIGHLY recommend.
