It gave me an option to nail it to the wall or keep it freestanding and since I am not 100% sure where to place it permanently and my son is still able to use it without nailing it to the wall and fear it will topple on him is a bonus. It's a great space saver as well and allows the room to not look so cluttered like your typical desks. VERY easy to put together. Took me no more than 30 minutes alone while watching TV. Looks great and works great for the price. Now time to decorate it!
