2D box colliders not touching but are colliding, how to fix?

I am having an issue with my 2D project in Unity 4.3. This depicts it.

The orange is a 'player' with a RigidBody2D and BoxCollider2D and the blue is the 'ground' with also a BoxCollider2D. My question is, why do they seem to float and how do I fix it?

They are colliding as I tested with:

 void OnCollisionStay2D(Collision2D coll)
 { 
     Debug.Log("Colliding"); 
 }
