Healthy Home, Healthy Planet


We take pride in knowing that every Stem product is made from the best available materials so it's not only eco-friendly, but also home-friendly.

Poly Foam Cushions + Fiber Pillows

With this filling option we'll use CertiPUR-US® certified certified poly foam (high resilience) on your seat cushions, and fill your back pillows with polyester fiber. These are free of fire retardants to meet specific criteria for physical performance and indoor emissions. We use certified organic cotton for all internal lining. Overall this selection provides a soft but very supportive sit.

Poly Foam Cushions + Down & Feather Pillows

When this option is selected, we use the same CertiPUR-US® certified certified poly foam (high resilience) on your seat cushions, but fill your back pillows with down feathers to create a slightly softer look and feel. Our feather/down fill option are byproducts of the food industry, and are cleaned with non-toxic substances. All these materials are all free of fire retardants.

Natural Latex Cushions + Wool Pillows

With this option, we'll make your furniture all natural from the inside out. We layer the entire frame, arms, and seat cushions with certified organic natural latex. Natural latex is made from the sap of rubber trees, 100% natural, very durable, and is made with no harsh chemicals. It's also bacteria, mildew, and mold resistant. We wrap the latex and fill the back pillows with domestic OEKO-tex certified wool which follows sustainability and cruelty free standards and is free of all chemical additives. Certified organic cotton lining is used for all internal linings. This is the ultimate option if you're looking for all natural furniture.

FSC Hardwood Frames

We hand craft all our upholstered frames with kiln dried hardwood sourced from FSC certified domestic forests. We use water based glues with zero VOCs and don't take any shortcuts with plywood or cheaper woods.


Ordering was a simple process and the sales staff was kind and friendly. I purchased living room furniture online without ever seeing a STEM piece of furniture in person but ordered because of their commitment to toxic free living. My furniture was delivered on schedule and STEM kept me informed throughout the entire process. I am very happy my purchase, the furniture is beautiful and well made. I will definitely order again.

Love our couch!

Derick A. / Rumford, RI at August 11, 2017

We have a son with eczema and a dust mite allergy. We got rid of our old foam furniture and are so happy to have a beautiful wool and latex sofa (which is dust mite resistant!). The order process was very smooth and Stem was easily to work with. The delivery took longer than expected - thus 4 stars instead of 5 - but they did upgrade to white glove delivery for free. We are grateful for a safe, custom, and high-quality alternative to typical toxic furniture!

Great couch, well built, expect to have this for many years to come

John C. / Dublin, CA at March 2, 2018

We love our new Rio sofa. It's comfortable, looks great, and best of all, made with non toxic materials. I absolutely recommend STEM, and will purchase more pieces in the future.

Kate O. / Griton, CT at March 4, 2018

A truly lovely sofa on the whole: nice lines, great fabric, modern but not austere. Also love the fact that it does not contain fire retardants. It's worth noting that Stem worked with me extensively to ensure I wound up with the right sofa. They are true to their word that they will make your sofa right and even accept returns—an exceptional company. The only caveat is that the sofa is very firm, though it is slowly improving in this respect. I'd have liked it a bit softer, more plush, but I'm still—overall—quite satisfied with my purchase, and can't say enough good things about Stem as a company.

Pascha S. / Lincoln, NE at June 6, 2018

This is a very handsome sofa and the build quality is best-in-class. Plus the customer service is responsive and STEM takes care of its customers. Very happy with my purchase!

Dan W. / Madison, WI at July 23, 2018

My experience was great! I contacted STEM with a specific design that I wanted and they made it to order. I received updates as to what stage of completion the couch was in.
