There is a extremely minor curve to this item but it is still fully usable. It does cause one of the corners or sides to lift up slightly. But the weight of building bricks on top of it typically flattens it out. If the bricks are not heavy enough, this may not be achieved. Please review photos, they show the exact item you'll receive.
