That is an elfa system from The Container Store. The "rack" is a ventilated shelf divider that pops onto the ventilated shelves. The wire shelves have birch wood trim on the front edges. All of this is available at The Container Store where the in-store designers will do the space planning for free! www.containerstore.com
