Sofa cushion foam explained

Sofa cushion is primarily made from sheep hair, feathers, and natural cotton. These traditional material items are primarily used as stuffing material in the overall making of sofa cushions. This stuffing material always required special care to maintain its original shape. If you fail to maintain proper care of feather, cotton, and sheep hair-based sofa cushions, it will become flattened and saggy with the passage of time. In the mid-20th century, a German chemist Otto Bayer did some routine experiments with a plastic-based product called polyurethane, and in 1941 he discovered a material like foam from it.

This research continued up to 1950 and then this foam was first time used as a filling stuff in the making of different furniture items. This filling stuff gained early popularity because it is comparatively more comfortable and economical than other traditional options. The major drawback of foam made from polyurethane is its high flammability and lower resistance, which is why manufacturers introduced new foam made from polypropylene into the market. The foam made from polypropylene plastic is more durable and adaptable than polyurethane foam. This detailed analysis also helps you to find the best filling for sofa seat cushions.

Verify the foam density for your sofa cushion

The first and most important step in replacing your sofa cushion foam is verifying its density. It will help you to find the right density of the replacement foam. You can easily find the density of the new foam by dividing the weight (Pounds) by the length x width x height (feet). Finding the density of the foam also helps you in the assessment of the required space in your sofa cushion cover. The recommended density for new foam is 1.8 per cubic feet according to industry norms, but you can also use the foam with a density of 2 to 2.5 per cubic feet.

If you decide to replace your sofa cushion with high-density foam then you can avoid adding extra padding material to make it fluffier. The new replacement foam is normally available in the form of blocks. It is quite possible that high-density foam initially looks firmer but it will adjust with the passage of time.

Measurement and cutting of foam

The measurement of foam is a crucial step in the process of replacement of sofa cushion foam. Sometimes people use old cushion foam to take measurements for new foam but this is totally a wrong approach. The best way to take measurements for new foam is to use your sofa cushion cover. You can easily measure and mark the width, length, and height from one corner to another corner by using the measuring tape. You can also cross-check the length by taking measurements from parallel dimensions.

It is recommended that you spare a space of 1 to 2 inches from the original measurement, which helps with the adjustment of replacement foam in the existing sofa cushion cover. You need to be very careful while marking the measurement of replacement foam. Once you have done with the measurement of the new foam, you need to cut the foam by following the marked lines in the final step. Before cutting the new foam, test the sharpness of the cutting blade on the disposed foam that you have separated from the existing sofa cushion cover.

In the third step, you need to cut the extra batting material from the corners of the new foam. In the last step, you simply need to stuff this new foam in your existing sofa cushion cover.

When you have completed the replacement process, you must sit for few minutes on the new sofa cushion so that the new stuffed foam will adjust to the existing sofa cushion cover.
