INFLATICUBES

At first glance, it might appear that InflatiCubes are as safe as a piece of furniture can get—and for good reason: They are! After all, there are no hard parts to bang yourself on, nor any sharp edges to cut yourself with. And yet, please remember that, while InflatiCubes serve the purpose of chairs, they are not chairs. Should you attempt to lean back or recline on one the way you might with a real chair, you could fall off the back, bang your head on the floor, and suffer harm ranging anywhere from a nasty bruise to a subdural hematoma. So please exercise caution at all times when sitting.
