This version of our popular house bed comes with front, side, and back railings for those “extra-active” sleepers... Make the transition from crib to "big boy/girl bed" exciting for your little one! It is made of smooth, solid wood boards and put together with quality screws for sturdiness. Comes with wood pieces, all screws, and easy to follow instructions. Wood Type: Poplar- Furniture grade and knot-free. Considered a hardwood and has more of a lighter tan look, with some color variance that can get a little darker brown toned. At times you may receive wood that has a green tint to it. This is because we mill it down and expose wood that hasn’t seen much light or air yet. Over the course of a few days or weeks (depending on the lighting and air movement through the room) the green will fade out to light tans and browns. Check out our other items and feedback! Tools required for assembly can all be found at any hardware store. You will need a #2 size square bit (6” long style), a standard Phillips (+) bit, a cordless power drill, and an extra set of hands.
