The Nomad Platform Beds come with a set of 15" legs which give a platform height of 15". We also offer these sets of 12" legs or 18" legs for purchase which can be used instead of 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.
