The Jiyoung Seo’s Sai Wall Storage Unit isn’t just useful, this shelving is quite fun too. Having in mind the fact that it’s made from soft silicone, which enables the unit to be quite flexible (besides its modular, shifting cubes), which should definitely not come as a surprise. This designer bookcase is a one-of-a-kind piece of ‘furniture’ which enables homeowners to stash pretty much anything between the crevices. It’s bigger than it seems in the images that let you rest quite a bit in its embrace. Each and every cube lights up with a soft glow to serve as atmosphere lighting. Its users can even pin messages onto the surface of this designer shelving.
