Perhaps you are in need of some replacement foam or you have just begun a new project. Our company offers a selection of foams that are perfect for any project, furniture, or upholstery needs. We can custom cut to any size. All Standard options or selections are in inches; example 3 x 14 x 14 is 3" x 14" x 14"

We offer three varieties of foams based on density: 1.4 lbs. per ft³, 1.8 lbs. per ft³, and 2.0 lbs. per ft³. Really, this is a choice between good, better, and best as foam of 1.4 lbs. will last from 3 to 5 years, foam of 1.8 lbs. will last from 7 to 10 years, and foam of 2.0 lbs. will last over 15 years.

All three varieties are moderately firm and have a compression rate, or ILD, of about 30 lbs. This firmness is perfect for a variety of projects including mattress tops, interior and exterior cushions (home décor, cars, trucks, boats, etc.), and table top protectors. The foam is very easy to cut and manipulate if needed.

After several month I have notice most people are looking to replace sofa cushions. Here is how to determine your correct foam size needed. Please measure your cushion cover with the foam inside from seam to seam. Left to right, front to back and top to bottom. Use the center of each side. Then add 1 inch to each dimension. This is the correct foam size to properly fill your cushion. I can also provide Dacron to cover the foam with accomplishes two things, allows the material to move without causing abrasion on the foam (like sandpaper on wood) and it can provide a bit of a crown, though your properly size foam will do that mostly.

If you need a unique size or particular firmness, please contact us and we will provide exactly what you are looking for. Or if you have a large job and need to order in bulk, we can certainly supply that too.

We recommend investing in a more dense foam, especially if your project (such as a family sofa) is going to receive heavy use. Although denser foam may cost slightly more, its value and durability are well worth the investment and expense of future repairs.

For first-time buyers, foam varies in color and changes slightly over time. However, the foam is “color fast” and will not bleed into or through the colors of your fabric.
Any foam orders thicker than 6" or longer than 94" may have a glue seam. We use water based glue, so no toxins or smells to worry about and the seam is stronger than the foam.

Custom foam orders are not refundable so please measure twice before we cut once. While we strive for exact cuts, foam compresses while cutting and will generally be with 1/8" but could be 1/4.

Our company ships UPS or USPS, typically ground, but if you are in need of a priority order then we can customize your shipping details. The shipping costs are determined by dimension and weight, so we try to minimize the size of the package. This means that your order may be vacuum sealed upon arrival. Additionally, the sealing prevents moisture and debris from contaminating the package. Upon opening, allow the foam to expand for at least two days. Denser foam will expand quicker, returning to its original shape. Do not leave the foam in the packaging for too long and be sure to cut open the package carefully upon arrival.

Most importantly, we guarantee 100% customer satisfaction and strive to be open and communicative with all of our buyers. If you have any questions or problems please contact us so we may resolve any issues and give you the best experience possible.

Our company has used these foams in our own custom furniture and upholstery projects for nearly ten years, and we hope to help you bring quality and success to your own projects and business.
