How To Measure Your Sofa Cushion Foam

To get the best measurements for your foam cushions, it is advised to always use your current cushion covers where possible. Old cushion foam may have become misshapen and not provide accurate results.

First, measure along the cover seams from corner to corner. You should pull the cover taught to get the best fit. Ideally, you should measure the back and front of each cover as measurements may vary between sides.

Next, measure the depth. Go from seam to seam. If piped, measure between them. The foam you order should be the size of the cover’s border width. Please factor that Dacron will add approximately 1cm to the top and bottom of your cushion.

Do not measure across the middle of the cushion. It may be domed and compromise your measurements.

Lastly, choose the correct shape from our templates and input your measurements.

Sheila Squires

All the foams were perfect sizing from my order. They were delivered to my daughters home in Cornwall and I had made the covers from her sizes. I was very pleased that all the covers fitted perfectly when I eventually visited and put the cushions in. Thank you very much for your help and good service.


High quality. Great products arrived really quickly. Much better quality and much fuller than original cushions.

Toni Williams

Perfectly fitting seat for my reused cover. So pleased with this along with the other 2 seat cushions ordered. New sofa, fraction of the cost of replacing the whole item. Could not be happier and thoroughly recommend this company. Great staff and communication.
