For Back Cushions
Cushions in any room have the ability to make or break your experience and enjoyment at the moment. Have you ever found yourself feverously fluffing up your sagging and limb back cushions before your friends arrive for an enjoyable evening? Or after that evening, when walking back through the same room do you notice that your cushions are in even worse shape than before? Back cushions are the bane of upholsterers for this very reason. The lack of support and the sheer absence of structure in your back cushions is frustrating, to say the least. We have found in our years of experience as upholsterers that one of the best solutions for this persistent problem is to add foam inserts in your back cushions. Foam not only adds structure and support to your back cushions, but it also is a longer-term solution compared to other options. Through tests, we have found 18 (1.8) Density foam to be the perfect density compared to 26 (2.6) Density. Even though 26 Density is higher in quality, 18 Density offers a softer and more comfortable feel. And since back cushions do not take nearly as much abuse as seat cushions, these will last for years to come.

For Seat Cushions.
18 Density is a great option for replacing your foam inserts in your seat cushions if you are on a tight budget. Even though this is the industry standard, we highly recommend you spring for 26 Density foam instead of 18 Density. With that being said though you will have years of use to enjoy your new seat cushions.
