How To Measure Your Foam

If possible, it is always best to measure sizes from your existing covers. Measuring old foam is not always accurate as foam can become misshaped over time. Measure your covers from corner to corner along the seams, pulling the cover taught to ensure you get a good fit. It is always best to measure both the front and back of each cover as some cushions can vary in width from front to back. Again, when measuring the depth of a cushion it should be done seam to seam, if you have a piped edge cover measure between the piping.

You should order foam to the size of the cover border width and then add Dacron and stockinette to get the best fit for your cushion. You should never measure across the middle of a cushion as it may have a domed top which will affect your overall measurements. Please select the appropriate product shape from our list and enter your dimension as per the measuring process above. If you can't find what you are looking for, please do not hesitate to give us a call and we will be happy to help.

Note for Sofa Cushions: Our regular advice is to measure from seam to seam. However, if your cushions rise significantly past the seams, you may need to add extra depth for a fuller fit inside your cushion covers. Choosing to include Dacron will add approximately 1cm to the top and 1cm to the bottom of your foam. If you are replacing a domed cushion that isn’t shaped like any of the templates we offer, please contact us for assistance.
