We recommend batting for most seating cushions, usually dacron with a book wrap. Most important, however, is to be sure the batting on your chaise cushion matches the batting on your other seating surfaces, if they are part of the same set or sectional. If your chaise cushion stands alone, then batting can be optional. A Dacron bookwrap gives an upholstered seat cushion a full, comfortable, rounded look that you see in most interior furniture. Without it, your chaise cushions won’t fully fill out, and will often show wrinkles in the fabric. For an even fuller look and extra comfort in your chaise cushion, check out our down or poly-fill cushion envelopes. We guarantee you’ll feel the difference.
