Platform Cushions

(separate boxing, fastened to a back board)


Platform Cushion Graphic

Note: Estimates add 3 inches (7.62 cm) to the boxing for folding over the back board.

Unit of Measure inches cm
A. Finished Width (?)
Intended width of finished cushion. Foam or filler should be oversized by 1% or a minimum of 1/2 inch (1.3 cm). Thus, the foam width will be at least 1/2 inch greater than this measurement and, for wider cushions, 1% of length greater.
B. Finished Length (?)
Intended length of finished cushion. Foam or filler should be oversized by 1% or a minimum of 1/2 inch (1.3 cm). Thus, the foam length will be at least 1/2 inch greater than this measurement and, for longer cushions, 1% of length greater.
Decimals!
C. Thickness (?)
Foam or filler thickness without compression.
Decimals!
Quantity (?)
Total number of cushions needed with these dimensions.
Integer!
Fabric Width (?)
Useable fabric width -- sometimes called nominal width (often 46, 54, or 60 inches -- 116.8, 137.2, and 152.4 cm)
Numbers!
Plate Length on Fabric: (?)
If there is a fabric pattern, it may be preferred to run it along the cushion width or its length. Specify here. "No Preference" results in the most efficient fabric utilization.
No Preference Length Width
Boxing Length on Fabric: (?)
If there is a fabric pattern, it may be preferred to run it vertically on the boxing width or on its length. Specify here. "No Preference" results in the most efficient fabric utilization.
