The laptop-laidback has allowed me to continue working while awaiting my surgery date for my back (a microdiscectomy at L5/S1).  The only position I am reasonably comfortable in is to be completely flat on my back in bed.  The laptop-laidback has allowed me to work on my laptop with surprising comfort.  It's flexible design made it easy to adjust to suit my preferred and most comfortable position.

Even after surgery (its been two weeks now), I find I still use the laptop-laidback to aid in the healing process and minimize pain while working.
