These are quality bed frames. They were quite easy to assemble (30 minutes)and all the parts and pieces were in excellent condition. The package of boltsscrews were a bit jumbled up inside their package but with common sense you can figure it out. The frames are sturdy and solid. I ordered 2 twins for a guest room (mainly will be used by adults )so I was concerned about weight capacity in this size. This has a 330lb capacity so I don’t doubt they will live up to that. Excellent amount of storage underneath. Overall I’m super pleased with this product. I did order the 10 inch mattress as recommended and it’s perfect for this frame. Delivery was very reasonable as well.
