I purchased this Twin bed for a guest room that is decorated in cabin décor. It arrived in a large flat box with easy to follow instructions for assembly. The only tool needed is an allen wrench or "Hex Key", which is included. The assembly took less than an hour for one person. I used the "higher" option for the height and used a 12 inch memory foam mattress that I also bought at Wayfair. (No box spring needed)  Even with the 12 inch mattress, it's a perfect height for the average adult or child. This bed is very sturdy and you will love the charming appearance.
