Very sturdy, and solid. Had a few chips and cracks in the wood during unpacking the bed which was disappointing seeing how much I paided for it.. The Wood cracks if screws are tightened too firmly. Have a power drill handy for the slats if you are putting the bed together yourself. My kids love the bed. The entire family has layed on both the top and bottom bunks. Very sturdy...Book shelf and bottom drawers help with space tremendously. It took 31 days for us to receive oit bed after purchase.
