Frequently Asked Replacement Cushion Questions

Do You Have Tips For Measuring A Custom Triangle Cushion?

When you select your shape, you’ll be asked to input values into each field. The fields will depend on which shape you select.

  1. Talk to our customer service team: We both want your cushion to be perfect. Even if you feel confident measuring, customers who use our customer support service are generally more satisfied with their order.
  2. Use a rigid measuring tape: A metal tape measure or yardstick will give the most accurate results.
  3. Don’t round your measurement up or down: We use very expensive and precise machinery to cut your cushion. Give us the most granular measurement you can.

Custom Cut Foam
“I ordered custom cut foam for a chair cushion. I received the order timely, and it was a great fit. The cushion looks like it did when it was new. Excellent quality, excellent fit, and excellent service! I would definitely recommend to others!”

My old chair’back!
“The FoamOrder people I dealt with were lovely from beginning to end. They delivered a quality product in the time frame promised, and the new cushion was fairly easy to put into the old cover. The original cushion of all feather was no longer fluffable— no amount of shaking or putting in the dryer on air would help more than a few minutes.. My 30 year old chair is once again comfortable and I have you to thank!”
