The accurate measurement of a sofa cushion is a fundamental step for ordering a replacement foam insert or commissioning a new cover. The most reliable method involves measuring the existing cushion cover, not the old foam insert, which has likely compressed and lost its original shape over time. This approach ensures that the new insert will properly fill the fabric casing and restore the cushion's intended fullness and support.
To begin the measurement process, the cushion cover should be removed and laid flat to smooth out any wrinkles. The three primary dimensions to record are thickness, width, and depth. The thickness, or height, is determined by measuring the border panel of the cover from the middle of the top seam to the middle of the bottom seam. For the width, measure horizontally across the front of the cushion from the left side seam to the right side seam. The depth is found by measuring from the front seam to the back seam. During each measurement, it is crucial to pull the fabric taut to get the most precise reading.
For irregularly shaped cushions, such as T-cushions, it is necessary to measure the longest points for both width and depth to capture the full dimensions. It is a common practice to record the measurements and then double-check them for accuracy. When ordering replacement foam, many suppliers suggest adding approximately a half-inch to the width and depth measurements to ensure a snug fit that prevents the insert from shifting inside the cover.
