Received the bed frame earlier than expected. Arrived in one headboard sized boxed. It is, however, VERY heavy. Especially if you have stairs, definitely need two people to move it. 
Assembly is straight-forward and took about an hour and a half. 
The bed frame is sturdy and definitely worth the heavy weight of the box to yield a sturdy final product. 
I was initially concerned that since there is no “lip” on the sideboards for the bed to sit in that it would scoot around, however it does not move at all. 
My mom came to visit and was so impressed she’s buying one!
