Ninja do 2 x 2 drawer fryers but they are aboot 50mm too big for the cupboard ie fryer is 400mm and the cupboard is 350mm.
You know you need to allow good ventilation around an airfryer? Presumably the aforementioned cupboard is just for storage?
Have a look at the Currys or John Lewis site and see what meets your needs size and spec wise?
