At Gimme the Good Stuff, I’ve spent over a decade researching and vetting non-toxic products—and few are more important than your mattress. Unfortunately, mattresses can be a significant source of toxin exposure, and you really want to make sure you’re getting the best organic mattress when you invest in a new bed. Fortunately, the safest mattress does not mean the most expensive mattress.
In our Safe Mattress Guide, we highlight just four brands as the Best Stuff, meaning they’re fully certified, free of all harmful materials, and aren’t owned by parent companies that pollute the environment by manufacturing toxic mattresses under another brand name.
Happsy is one of those four top-tier brands in our guide. It’s our mattress pick for kids, one of the only mattresses that’s truly safe and affordable, and—especially important for busy parents—it’s by far the best organic mattress in a box.
This year, Happsy sent a mattress for my 11-year-old son, Wolfie, and it’s only reinforced what I’ve said for years: Happsy is a no-brainer if you care about safety, quality, value, and convenience.
Why Happsy Is the Best Organic Mattress in a Box
The boxed mattress space is crowded—and unfortunately, full of greenwashing. Many (perhaps most) mattress companies throw around terms like “eco,” “natural,” and even “organic,” but use questionable materials and misleading certifications.
Happsy is different. Here’s why:
- Top-Level Certifications: Happsy uses only GOTS-certified cotton and wool and GOLS-certified latex. You can learn more about these certifications in our Mattress Guide, but the TLDR is that they are the gold standards for mattress safety certifications and offer the best peace of mind that your mattress isn’t off-gassing anything dangerous.
- The MOST Certifications: Happsy mattresses are certified by GREENGUARD Gold, EWG, Made Safe, FSC, and more. These are really just gravy when Happsy’s already got GOTS and GOLS certifications, but we’ll take it!
- No Polyurethane Foam, Flame Retardants, or Glues: Happsy utilizes just safe, simple construction, with materials like organic cotton, organic wool, pocketed steel springs that don’t use glues or adhesives, and GOLS-certified latex.
- Ethically Made in the U.S.: Happsy mattresses are manufactured in a GOTS-certified facility using sustainable manufacturing practices.
- Ships Compressed in a Box: This makes delivery and setup a breeze—without compromising on materials or comfort.
Why a Non-Toxic Mattress Matters—Especially for Kids
Unfortunately, even “organic” mattresses can be loaded with noxious chemicals, from synthetic latex made from carcinogenic styrene to adhesives that may contain formaldehyde. This chemical cocktail releases VOCs (volatile organic compounds), which are linked to a host of health problems, from respiratory irritation to cancer.
Recent research has underscored just how important clean sleep environments are. For instance, a 2025 study published in The Guardian revealed that many children’s mattresses contain phthalates and flame retardants that can off-gas as kids sleep, potentially impacting respiratory and hormonal health.
Mattresses can be one of the biggest sources of VOCs in a home, and choosing a safe one is critical. Happsy makes that choice easy with the best organic mattress in a box.
Our Experience with Happsy
Wolfie’s twin mattress arrived neatly boxed and fully expanded within less than an hour. Unlike many other boxed mattresses, this one had no chemical odor—because there are no sketchy foams or adhesives to off-gas.
Wolfie finds his Happsy mattress super comfy and supportive (we chose the Medium-Firm model), and I’ve spent my fair share of time on it as well so I can attest that it offers a great night’s sleep, even for a grownup. This is the best organic mattress for a growing kid who still spends a lot of time sleeping—and for a parent who wants to protect that time from unnecessary chemical exposure.
