The Plastic Plate Surround is a clip-on rim that turns an ordinary dinner plate into one with a high edge, so food can be pushed against something instead of over the side. Adjustable clips hold it on plates between 20 cm and 30 cm in diameter, which covers most household crockery, and they grip without marking or damaging the plate. The deep inner lip stands 3.4 cm high and gives the spoon or fork a barrier to work against when scooping, which helps anyone eating one-handed or with unsteady hand control to finish a meal. The surround weighs only 25 g, fits and removes in seconds, and is made from a shatter-resistant material that is microwave and dishwasher safe up to 70 °C.

A plate guard is one of the least intrusive mealtime aids, because the person keeps eating from their own plate and only the edge changes. Fitting a wide range of plate sizes and washing up with the rest of the dishes means it can be used at every meal rather than becoming a separate routine, which is what makes it practical day to day.
