Paul McCobb's X-based ottomans are iconic pieces of mid-century modern design, celebrated for their minimalist elegance and functional form. These ottomans typically feature a brass X-base frame with a cushioned top, embodying McCobb's philosophy of "no-nonsense" design—emphasizing simplicity and utility. McCobb's association with reputable manufacturers like Calvin Furniture and Directional enhances the provenance and value of his pieces.

This legacy contributes to the enduring appeal and higher prices of his furniture.
