Ten universal wheels sit under this four-panel screen, and each one brakes so the 19-pound frame holds its angle once folded into place. Opened out the screen spans 89 inches and stands 68 inches tall, with each panel measuring 22 by 68 inches. The hinged panels let you shape an L or a zigzag to wall off a desk corner, then fold flat again when the room goes back to normal. Wheels of 1.5 inches roll quietly over wood or tile. Polyester panels on a metal frame keep the weight low enough to reposition alone. Use it to carve a study nook out of a shared living room.
