Sturdy twin frame, and super basic assembly. The close weld threw me off when connecting the parts, hence the mallet included. Fits a T&N twin mint just fine. Take weight of bed and person in mind. Slats are at a correct spacing for mattress support and airflow. Do not let kids jump on bed. Slats aren’t necessarily flimsy but made at a thickness to accommodate frame configuration.  Higher frame preferred, but keeping under bed space clear for the boogie man.
