We have a lovely and tall twin loft bed that is entirely disassembled. It's called Ginger by Night & Day - full details and photos from the manufacturer are here:  https://nightanddayfurniture.com/closeouts/ginger-twin-loft-bunk/.  It's quite tall (approx. 6 ft to the top of the mattress), so best if you have ceilings that are 9 feet or higher. (You could definitely saw off several inches from the bottom if you're good at that.) See full dimensions here: https://nightanddayfurniture.com/wp-content/uploads/2025/05/Ginger-Loft-Bunk-Dimensions.pdf. Note: Our version does not have the little desktop/shelf shown in the manufacturer's photo, but it has everything else that is shown. Sorry I don't have photos of it installed in our house. It's in excellent condition, just a little dusty from sitting in our basement for a few years since our kid got too big. It's very solid, excellent quality (we paid a lot for it!), and a great solution for a child or a small room.  To pick it up from our house, you will need a car or truck that can handle segments that are 83 inches (7 feet) in length. They're not especially wide, but they are long.
