This complex was made in order to give a high level feeding area high off the ground. Its very nice for families that have dogs or children. This piece is mounted among four studs, spaced 16 apart. (If your studs are spaced differently, let us know before ordering and, if necessary, well build you a custom piece accordingly for an additional fee.) We use solid wood for the shelving and mounting posts, and thick heavy-weight canvas for the hammocks. All of the brackets come attached for easy installation. The Bunker comes with two half-pint food dishes, and all of our furniture also comes with screws and drywall anchors. We have new easy-to-wash, waterproof marine canvas! With this fabric, cat hair and other debris wipes off quickly with a wet towel If you want this option, just select a fabric that says “Waterproof” in the drop-down.
