If you’ve ever gone to an art gallery and had the overwhelming urge to sit on a painting of Mona Lisa, well now you’re in luck. You can enjoy leisurely evening of relaxing and sitting on the mischievous Mona Lisa. Then when you’re not using it, you can hang it on your wall and it can look like a perfectly normal and massively heavy piece of artwork. Hopefully you don’t leave any butt imprints though, that’d just be awkward to explain. It’s not for sale sadly, it’s purely a design by Kwang Hoo Lee, who I think might be seriously deranged to have come up with this one.
