Choosing Foam For Your Replacement Cushion
There are many different foam types used in seat cushions and they vary greatly in quality. The better the quality, the more expensive the foam is. However, with this increased price comes better durability, longevity, and comfort.
Cheaper foam seat cushions will be less comfortable overall and wear out quicker from use. Higher quality foam can last for a decade or longer. However, if the replacement foam for your couch, sofa, and window seats only get occasional use, then a less expensive foam replacement option is viable.
Another thing to consider is the firmness of the foam. The average foam used in furniture is a medium-firm firmness. However, for heavier people, a higher firmness would be better to ensure that the foam does not bottom out as weight is applied to it.
Recommendation Guideline:
High Density Foam: Industrial grade foam that is ideal for furniture that is used periodically. We recommend this foam for back cushions. Most of the weight is allocated to the seat cushion, not the back cushion. As such, the back cushion will last longer than the seat cushion and will not provide a noticeable difference in comfort than higher quality foam.
Lux Foam: An upgrade from High Density foam. Available in a firmness of medium-firm only, it is better for those who prefer a firmer cushion.
High Resilience Foam: An excellent quality foam that is very comfortable and durable. Can be used both indoor and outdoor.
Memory Foam: A viable option when used as a top layer and glued to a firmer base foam. Solid memory foam cushions are not recommended because they lack support and will bottom out when sat on.
Dry Fast Foam: Its porous open-cell construction makes it for an excellent outdoor cushion solution. Water flows through this foam and it dries quickly.
We recommend adding Dacron to your replacement foam order. Dacron will add softness and puffiness to your seat or cushion when you insert them into your cover. It will also provide a rounded edge to the corners of your seat cushion. You will also need spray adhesive to glue the Dacron to the foam.
