ABSTRACT:
Portable platform assemblies, e.g., tray, desk, or shelf, are provided for placement on the backrests of chairs or seats or similarly vertical surfaces. More particularly, the subject invention pertains to platform assemblies that can be placed on the backrest of a front seat in a vehicle, for example, but not limited to, an automobile, and are useful to someone sitting in the back seat of the vehicle. The tray or shelf assembly can be extended, as well as adjusted to a variety of angles useful for writing, reading, eating or other uses. The platform assembly also provides a safety feature that allows the platform to be automatically collapsed and folded upwards or downwards when sufficient pressure is applied at or near the front of the platform assembly.
