Portable Laptop Table Wanted

Does anybody know where we can buy a Portable Laptop Table? Ian want's to be able to sit in his armchair and use his laptop on a proper Laptop Table that can be swung to the side of the chair when not in use. We have tried the large stores around Elche & Crevillente.

We have found quite a few Companies that do these on the internet, BUT they must deliver to Spain.

Hoping for some good feedback on this one.................................
