ERYE Velvet Sofa Set

No frame, no legs and no assembly: this velvet set is solid foam, so you can rearrange the seats and the ottoman whenever the room changes. The 80.3-inch version seats four at 37.4 inches deep, and a 110.6-inch version runs longer. Push the ottoman against the front and you have an L-shaped lounge or a spot for a guest to sleep.

Hidden straps under the seats hold the pieces together, and the undersides hold the floor. It arrives compressed, and the foam needs time to reach its full shape and its 17.7-inch seat height. One limit: the velvet covers do not come off, so spills get cleaned in place with a damp cloth.
