I am about to design an ottoman. I want it to be the same height as my couch. I want to, as best as I can, figure in the compression of the foam. Is there a chart, or a general rule of thumb for compression ratio of different types/thicknesses of foam.
I understand the fabric’s tension will have an effect on the compression and the overall height of the foam as well. Can this be figured into the design too?

Build it to the height you want it to be when finished. If the fabric is compressing the foam enough to change the height then it is streched to tight and is apt to tear at the staples. Fabric only looks tight due to the rounded corners.

ok.
Thank you.
Hi Scott ,
Foam is rated by it's density . The firmer higher density foam will cost more and is usually not sold except from upholster's or suppliers . We make cushions as part of our business for various pieces of furniture and have found the softer or lower density foams do not hold up .
Make your piece the correct height and the fabric will not change that .
good luck dusty
Thanks Dusty.
I have the frame built, and I will go to Osgoods in the AM.
Firm you say?
If you can get a high quality grade of a medium firm from an upholsterer type shop , not a big store as a rule they won't have the higher quality foam , just lower cost .
luck to you dusty
they are rated by this, see : http://www.carrscorner.com/foam.php
