The Nomad Platform Beds normally come with 15" legs which give a platform height of 15". We also offer these 12" legs or 18" legs that can be swapped out for the 15" legs. The 12" legs will give you a lower profile, but please note that the Rolling Drawers are NOT compatible with this option. The 18" legs are a good option if you are trying to create more clearance for a thicker mattress on the Trundle Bed - the 18" legs will allow for a mattress that is up to 10" thick for the trundle. The King size option will come with the 2 center legs required for the King size Nomad.
