Slat king bed frame a la West Elm

Now that you've introduced me to the West Elm on-line catalogue, I see a simple bed frame that would be perfect for our king size mattress: the narrow leg upholstered bed though the upholstering could be optional.  I just like the simple, low-profile.  Could you create a plan for this?
