We need to talk about corners. Not the kind you back yourself into after opening a wildly optimistic set of flat-pack furniture, but rather architectural ones – those 90-degree voids in your home that are so often wasted on dusty floor lamps and forgotten spider plants. Enter: the triangular bookshelf. A geometric overachiever that’s a master at turning forgotten corners into chic little libraries.
Gone are the days when bookshelves had to be big, boxy and bossy. In today’s world of ever-shrinking square footage and ever-growing reading lists, triangular shelving is not just clever, it’s crucial. These nimble little units tuck neatly into tight spaces in studio flats and micro-lofts, or that suspiciously small nook in your hallway you’ve never quite known what to do with.
They’re the design equivalent of saying, “Yes, I do read Tolstoy, and I do it efficiently.” But it’s not all about pragmatism. There’s something charmingly subversive about shelving that rejects the straight line in favour of the diagonal. It whispers. “I have taste and geometry skills.”
Triangular bookshelves have witnessed a surge in popularity thanks to – you guessed it – a viral TikTok moment. A user by the name of Mehreewin posted a video in which she detailed the struggle she was facing when it came to furnishing her strangely shaped NYC bedroom. Another popular TikTok user, known colloquially as the ‘Feng Shui Guy’, duetted her video with a solution involving a triangular bookshelf. Voila, problem solved.
In line with zen-centric trend, we’ve curated an edit of the best triangular bookshelves on the market – from minimalist Scandi angles to maximalist corner thrones – each one ready to rescue your room from the tyranny of the unused edge.
So, whether you're a die-hard minimalist with a penchant for precision angles or simply someone trying to store your ever-growing pile of cookbooks without sacrificing the last square inch of floor space, the triangular bookshelf is your unexpected saviour. It turns out the best way to think outside the box is to store your goods in a triangle.
