ROCK OUT

The ‘Cone’ phone stand created by Nendo for Italian firm Marsotto comprises a precision-milled block of marble (white Carrara or black Marquina) with a conical hollowedout void that naturally amplifies the music from your phone’s speaker. The piece joins the ‘Marsotto Edizioni’, a collection of exquisite marble designs by the likes of Jasper Morrison, David Chipperfield and Konstantin Grcic. £144, Twentytwentyone (twentytwenty one.com).
