SEAMLESS COMBINATION A perfected design. Neff is offering the first seamless vertical installation solution: SeamlessCombination. In this collection, uniform stainless-steel strips on each side merge two appliances into a single impressive unit. There’s no longer any need for a space between the two, which means they can be installed directly on top of one another, even when the appliances are of different heights. A 60 cm oven can be perfectly combined with a 45 cm warming drawer. The idea: two kitchen appliances that are installed on top of one another appear to be a single appliance.
