Furniture with silhouettes.

Furniture is floating because of the silhouette (the CS assumes (after pressing "F") the bench (for example) is already on the floor). Press once (sometimes twice) "F" to correct this. All the furniture with silhouettes have the same problem.

A technical explanation.

Originally written by Razorwing
What happens when you press F is that the model moves down until it hits the nearest colliding polygon on the Z plane. For stock Oblivion stuff that as good as always means it hits a polygon on the model's collision mesh. The collision mesh is invisible and controls whether the player bumps into it; it can be solid, like a wall, or hollow, like a plant that lets you pick ingredients. For custom stuff without collision meshes it lands on the polygon of the actual model. Collision meshes are always optimized, meaning they don't follow the same shape as the actual model. That's why pressing F can often lead to the object floating just above the surface. Presumably, pressing F a second time makes it land on the polygon of the actual model, i.e. lining up perfectly. Whether it happens or not often corresponds to how complex the surface is. For a flat floor, the collision mesh can use the same shape and position as the actual model, meaning stuff lines up perfectly. Of course, that doesn't mean it can't hit other models on its way down though.
