When purchasing a seat and back cushion set together, it’s important to know that they should usually have two different foam types. That’s because all of your weight rests on the seat cushion, requiring firmer foam. The back cushion only bears some of your weight, so you want softer foam for the back. FoamOrder’s ordering system walks you through the ordering process, allowing you to specify if your cushion will be used for a back or seat cushion, and recommending the right foam for soft, medium, or firm comfort levels. We offer three grades of traditional polyurethane foam, from low-cost less dense foam that can be used in areas that get minimal use, to our top-quality HR (high resiliency) foam that’s recommended for everyday use. We also offer organic latex cushions for the eco-minded, and a variety of cushion treatments from dacron polyester to organic wool or cotton batting to down and poly envelopes. We’re experts in foam and seating, so let our website (or our friendly customer service team) help you get the right seat and back cushions for your home.
