Cozy Desk
My Cozy desks, I bought 3 of them, is very helpful and convenient because it is not too high tech or heavy. It is sturdy enough for my laptop and sits conveniently on either of my two desks. I love having it at work.
I don't care for it on the bed because the bed does not provide a flat surface to rest on. Perhaps, I have to try a different configuration. It takes some effort to adjust, sometimes I think that I need three hands to make the adjustments.
