I read the reviews and knew that the nail heads where noticeable if you looked closely.  They are not individually nailed in.  So if you are someone that wants individually separate nail heads on the side I would not recommend this bed if that is a deal breaker.  The slats that come with the bed are not that sturdy though.  My husband and I went to home depot and bought some plywood to reinforce the support so the mattress is more firm.  Other then that we are really happy with the purchase of the bed for the price.  

Pros: great deal for the price, quick to assemble
Cons: needs more support, provided slats are flimsy
