Our Bunk Bed for small spaces is a fantastic addition to a children's bedroom or a guest room with its space-saving design. This twin over twin bunk bed includes full-length guard rails on the top bunk for safety. Constructed from superior quality hardwood, the bed is made to last for many years. Solid wood construction and iron alloy bolts keep the entire bed durable and wobble-free. Built in stairs make accessing the top bunk safe and easy, especially for children. The bed also comes with sturdy secured solid wood slats to ensure durability and comfort. A box spring is not needed with the built-in slats. Assembling is effortless with the included detailed instruction.
