And these seats can become quite costly. Don’t look like an ass spending a lot for custom cushions. Many chairs have a square or round seat that can accommodate a standard 12 x 12 decorative pillow. The key is to find a zippered pillow cover, remove the insert, and replace it with memory foam cut to fit the size of your seat. Using pillows that have irregular edges work the best. Try furry ones from Z Gallerie or West Elm. The memory foam can be purchased at Bed Bath and Beyond. This is just one more way to Pull It Together.
