Do you have an upholstery project that requires new foam for a cushion or seat? Here’s a guide to help you choose the right foam for your project…
First, I want to share a bit about how I deal with foam in my upholstery studio, along with a few entertaining alternative uses for urethane foam:
I’m a saver, a recycler, a stickler for minimizing the waste and useless by-product that emerges from my life & work. I use the blank sides of junk mail as scrap paper, throw match books (and spent matches) in the cardboard recycling, and use burlap scraps from upholstery projects as garden mulch.
So I have this problem that’s been bothering me…
Ever since I first dipped my big toe into upholstery, there has been one over-riding waste item (aside from the stinky old stripped-off fabric and padding that is beyond re-use) that I haven’t been consistently able to re-purpose:
Foam is expensive…
I buy it in sheets (54”x 82”) and half sheets (27”x 82”) and custom cut it into whatever size and shape needed for each project – a sofa cushion, a dining chair seat, back padding – and, inevitably, there is an odd scrap left over that’s too small to use on anything. Piecing them together is risky because the glued seam could open up during use, and ruin the whole upholstery job.
I hate throwing stuff away…
I think about what went into making that piece of foam (chemicals, resources, human labor, shipping) and I’m motivated to do what I can, so I’ve come up with a few uses over the years:
• Dog & Cat Beds: I go ahead and glue pieces together for this if I need to, since the puppies & kitties don’t mind and the zippered beds allow replacement (also a good use for old foam).
• Shred it for Pillows: I’ve heard there’s a shredding machine that cuts foam in to tiny pieces, and heard of a local guy who had one in his basement, but have not seen it or met him, yet…
• Toadstools: we make these small, medium & large mushroom-shaped stools that use layered foam, so I glue pieces for the bottom layer, and use an intact piece for the top layer (I sometimes do this with small chair seats too).
• Art: sculpt it, paint it, embellish it!
• Talking Balloons: You know, the cartoon balloons… always good for a laugh in the studio!
Here are some fun creations using urethane foam:
Okay, so that’s my 2-cents for re-purposing, but there’s really more to this story than finding CREATIVE ways to keep SCRAPS out of the landfill… which brings us to:
If you’re doing your own project with ANY kind of foam – replacing a sofa cushion, re-covering (with new foam) your dining chairs, or building a new window seat cushion – you’re going to need to know that there are different foams for different purposes.
Sure, you can go down to the local Joann store and buy their low density foam (and this might be the easiest solution for many of us who just want a quick fix and don’t mind the comfort factor so much), but there are NICE foams out there that your tush will thank you for in the long run. High density means less air, higher quality, and longer life.
Here’s a handy chart that will help you choose the right foam for your own reupholstery or cushion project:
The eFoam Store in Pennsylvania has a good explanation of how foams are specified using a 4-digit number: the first two digits representing density, and the second two digits representing ILD. For example, if a foam is identified with the number 1835, the 18 means a cubic foot of this foam weighs 1.8 pounds (The heavier a piece of foam, the longer it will maintain its shape), and the 35 means it takes 35 pounds of pressure to compress a piece of this foam to 25% of its original height (The higher the number, the firmer the piece of foam).

Natural Upholstery Materials.
Here at NaturalUpholstery.com we’ve shifted our focus to NATURAL LATEX foam, which has very different properties than urethane foam. Check out the post ‘How to Use Latex Foam in Upholstery’ or How to Choose Latex Firmness for Upholstery, and see our comprehensive FAQs to learn more about latex foam. If your’e seeking materials without flame retardants to use in your upholstery project, we have some natural & organic foundation materials available in our shop.
