Clear and easy assembly instructions included for each (1) the main bed frame and (2) trundle. The quality is stellar - lovely color and sturdy frame. The only reason I’m not giving it 5 stars the appliqué on the headboard and sides is a little off when it comes down to the stitching. I don’t mind it since it’s for a guest room and these little faults will likely be covered up by pillows and a throw.
