I grew up with a version of that green tray with handpainted flowers on the lower left ... except my mom's was yellow with pink flowers. I remember using it for meals in bed whenever I was sick as a child. I brought it back with me to New York one year when I discovered that my mom was going to put it in a garage sale. Then it was stolen from the storage room of my apartment building by one of the residents who had Alzheimer's and went around helping herself to things, including newspapers and laundry on the line. When our building was sold and people were discarding things before they moved out, I spotted the tray on top of a pile of garbage in the courtyard ... she had ruined it completely, having flooded it at some point.

i have one at home just like the green one on the bottom left. only the flowers on mine are different. if it is exactly like mine it sits flat like a standard tray table but you can also tilt the top like an easel. i use mine all the time.
