The tray is made of solid wood in a few different finish choices and the pillow it rests on is bean-baggy, shaping well to your lap. I always find myself balancing my laptop precariously in my lap until it's practically scorching my legs. I've even read that such heat can cause impotence in males using laptop computers in this fashion too frequently. All fears aside, I still think this is a helpful object to have around the house for laptop work, dining, etc.!!
