Breakfast In Bed Tray

I want something I can possibly be stored under my bed, and fold them on the bed and when I want to watch a DVD on my laptop, or a breakfast tray on it or whatever. I want to know what these are called and where I can buy one online or in a store in the United Kingdom. Thank you!

if you're in the UK try Ikia! Ekia or is it? you know what I mean.
