Grandma I love you to the moon and back laptray Lap Trays are of the highest quality and are manufactured here in sunny England by British hands! The neutral black cushion is generously filled with flame retardant polystyrene balls for stability and comfort. Lap trays are also very useful for LAPTOPS which allow the machine to ventilate naturally preventing overheating. 32x41cm - 12x16 Inches. Wipe clean with a warm damp cloth.
