Furniture articles have an integrally formed shell that generally has rounded features, the shell diminishing in circumference outwardly from a mounting surface, and a mounting portion configured to secure the shell to the mounting surface. A perimeter edge of the shell defines a mounting plane against which the mounting surface is to be secured. When the shell is secured to the mounting surface, the mounting portion is inaccessible and hidden from view. Furniture includes a shelving unit, a desk unit, a seating unit, and a bed.
