Can I place the Big Bag Bed on my driveway or do I have to place it on the ground?

Yes, you can place the Big Bag Bed on your driveway or on any other flat surface. However, remember that the Big Bag Bed is made of a porous fabric and, with proper use, will remain damp. The material of the Big Bag Bed does not stain however the water, which contains substances from the soil, could cause stain.  If placed on a wooden deck it will discolor and rot the wood due to the constant moisture contact from the Big Bag Bed. In these cases you may want to place a plastic sheet or tray under the Big Bag Bed.
