I ordered this for my parents bath their new W245. Everything on the advice of a friend who had just bought a mat at Aldi, but no good. This tray fits perfectly, especially if the floor is lowered, which is probably at the old B-Class series. Fits The increased storage, but not quite exactly. But perfect for lowering !!! ,, Even if it is absolutely odorless warm even slips nothing around it and the clamping hooks are not covered! Perfectly
