TV tray/ foldable table/small table (Milton)

Looking for a TV tray. I need a foldable tv table a small one I can do my writing on put my laptop, eat my dinner etc. while sitting on couch mostly. I know some times they come in sets of 4. If you could spare just 1, that would be awesome. You don't have to give me all of them if you don't want to. Please and thank you. Any condition as long as I can use it.
