Daybed and trundle were delivered together in a long compact cardboard box. Assembly was quite easy, it took me about an hour at a very relaxed pace. No tools were needed except the allen wrench included in the package (Note that I'm recovering from a broken arm and a broken knee, so I performed most of the assembly from a chair.)  The assembled bed looks great, and doesn't creak, but I don't recommend a heavy adult bounce around or subject the frame to a lot of lateral forces.  Overall, I'm pleased with the purchase for an extra set of guest beds.
