Looking for a couple specific products
 

I have been hunting for a couple products, and I just can't seem to find them.
I have seen small ones, but need something that can hold large text books. I want something to hold my book while I lounge or sit at my desk so I can read or type while the book is pointed at me. Something with a full range arm. Seems easy.

Also, I am looking for a table/tray that I can pull up when I am sitting on the couch and use a full keyboard and mouse when I want to game while sitting on the couch. I have seen small trays like this for eating, but they are flimsy and very small.

If anyone knows where I can get these, that would be great!

Have you tried the Levenger catalog? For example, Reader's Oasis Table - Reading Table, Laptop Table, Writing Table - Levenger.

I built myself a kneetop PC tray to keep airflow under my laptop and allow me to use a real mouse.

Took a sheet of 5mm MDF (offcut from a DIY project) that's about 80cm x 35cm.

Covered it all over with black duct tape.

Made corners out of PVC electrical tape (green/yellow earthing stripes as you ask).

Screwed a 60cm strip of 2x1 off centre (to the left) near the back edge to support the back feet of the PC.

Mouse mat to the right of the PC.

Keeps it cool, and means all the cables, USB hub etc are tucked away underneath.

Any of these be what you are looking for?
