Super sturdy. No qualms about sleeping in the top bunk. Looks great in the space. Was so glad to find a queen over queen bunk bed. Saves space while providing extra sleeping options. The ladder can be tough on the feet but some pool noodles can eliminate that. Took about 2.5 hours to put together, not bad. Very happy with my purchase. Even better, there is the option to separate the beds and use as 2 separate queen beds.
