Purchased this twin bed for our younger daughter. The oldest daughter put the bed together with ease. This bed looks great and is sturdy. Love the option of two heights for the side rails. We chose to raise the side rails to the higher option. Brought an 8" mattress (photo 1), felt it sat too low even with the higher siderails. So I decided to add a box spring to give more height (photo 2).  It is perfect for our teen. Would definitely reccomend this bed especially for the price.
