Dining chair cushions are usually on the thinner side, often from 1–3 inches thick. Most important is to make sure that the thickness and firmness of the foam work together to provide maximum comfort. This means that if your cushions are thin (1–2 inches), you need firmer foam (Everflex V54 for example) to make sure you and your guests don’t “bottom out” and hit the wooden surface of the chair. For dining room chair cushions that get everyday use, we recommend high-density polyurethane foam (our Everflex™ foam). For dining chair cushions that get used less often, our medium-density Econoflex™ foam should work just fine.
Dacron wrap is optional for dining chair cushions. Dacron batting is primarily to give a cushion a fuller look and a bit of extra padding, so if your dining chair cushion doesn’t need that, you can forego dacron wrap. If you do want the fuller look and extra comfort that dacron provides, we’d suggest a bookwrap treatment for a dining chair cushion.
We recommend that the height of dining chair seat cushions be between 18" and 20" from the floor. Any taller than this and shorter people won’t be able to rest their feet comfortably on the floor. Dining chair cushions are usually only 1–3 inches thick, so choose a thickness that will provide the proper seat height for you and your guests, taking the table height into account.
