More Info About Throw Pillows

Throw pillows are usually placed on sofas or armchairs but are also frequently used on beds and day beds. Throw pillows serve both an aesthetic and a functional purpose. Decorative pillows are commonly used to tie in color accents within a room, often drawing on the colors in drapes, walls or area rugs. From a functional perspective, throw pillows may provide back, neck and head support, although some throw pillows are very uncomfortable.
