A bookcase today is kind of a survival of times past because we all spend time at computers, laptops, ipads and e-books. But if a bookcase is not only a furniture piece but also an art work, such a piece can be very actual. The Concave Bookcase by Simon Pengelly through Joined + Jointed is a perfect example of such a piece. Produced in two halves it can be used as a single unit lining a wall – or, as in this case, two separate shelving systems. The bookcase comes in oak and walnut, and whichever choice of wood used, the curved vertical support system to the shelves creates a fun and lively place to display books, mementos and collections.
