Things you will need:

1. A Pencil or Pen.
2. Measuring tape.
3. Paper to record custom foam measurements and to draw your cushion on.
4. The cushion(s) that you plan on replacing the foam in.

Please read our foam ordering instructions in full before you start your order. If you need support before ordering your custom cut foam cushion or would like a brief consult, please email us at, include your phone number so we can contact you.


1. Measure your cushion with the cover on, from seam to seam, pulling the material and the measuring tape tightly.
2. Take the foam out of the cover and measure your cover itself to ensure the new foam grade will fit into it. Compare the size of both and and ensure they match closely; keep in mind that the old foam will wear unevenly and sometimes difficult to get a true measurement.
3. Round up your measurement to the nearest half size (if applicable). For example, 4.5” = 5”, 4.2” = 4.5”.
4. Enter the measurements in order A=is always Thickness B=Depth on a seat and Height on a Back C=Width make sure to add measurements to all fields.
5. If you DO NOT have a cover, simply measure the space around the foam to the nearest half inch.
6. Keep in mind that you can always stuff thicker and soft foam into a smaller space, but you cannot stuff thicker and firm foam into the same space. This is why we recommend measuring your foam with the cover off to ensure your new custom cut foam fits your cushion cover.
7. If you need a replacement foam insert for an envelope-type cushion cover, take the foam out of the slipcover and out of the inner cover, measure the foam directly to obtain the correct measurements.
8. Locate the cushion that resembles your shape from the Custom Cut Foam page.
9. There are four Categories 1) SEATS 2) BACKS 3) BOAT 4) SPECIALTY. Select the category that applies to the cushion you want to replace.
10. Enter the measurements in order A=is always Thickness B=Depth on a seat and Height on a Back C=Width make sure to add measurements to all fields.
11. If you DO NOT have a cover, simply measure the space to the nearest half inch.
12. We recommend measuring your cushion twice to instill confidence and for best results. Do not worry about being off by an eight of an inch, 1/8 rounds up to a quarter inch.

How do I choose the right foam density and firmness for my couch or sofa cushion?

1. Navigate to your selected foam shape page and select a foam grade from the drop down menu.

2. Select the foam that is best suited for you based on your preference of density, firmness and budget. Keep in mind that no matter what density you select it will be much better than what youare replacing!

3. Get to know your foam preferences first, starting with density. Once you have a preferred density, select your firmness within that density. The fitness will depend on your preference, how medium or firm you like your seat and/or back cushion.

For example, if you like a soft seat and are a lite weight a high density (HD) or high resilience (HR) foam in a medium firm may be for you (HR foams have the ability to bounce back up and hold up longer). Alternatively, if you have a lower back issue, a medium firm may be needed. If you are heavier with a bad lower back and prefer a firmer seat for better back support, the firm will help. 

Things to consider when selecting your firmness:

  • Since FIRMNESS IS A MATTER OF PREFERENCE we CAN NOT recommend or begin to know what is best for YOU. It’s all up to you!
  • All grades are comprised of 4 numbers; the first two represent the density or weight of the foam, and the last two represent the firmness or the feel of the foam.
  • As a rule of thumb, the higher the numbers the higher the density and the firmer the foam.
  • Foam will feel softer when sitting on it and firmer when lying on it. Choose firmness based on application.
  • Thinner foam in the same density and firmness will feel softer than thicker foam. For example, a 2” firm foam will feel softer than a 4” firm foam.
