These two mattresses are built on completely different philosophies — one is rooted in certified organic materials and coil-based support, the other is a polymer engineering experiment that happens to sleep on. I've tested both across six nights each, and the decision between them comes down to one thing: do you want natural materials with buoyant lift, or maximum airflow with instant grid-based pressure relief?

Specs Side by Side
Here's what's actually inside each mattress before we get into how they feel:
| Feature | Avocado Green | Purple Original |
|---|---|---|
| Comfort System | 2 inches GOLS Certified Natural Latex | 2 inches Hyper-Elastic GelFlex Grid |
| Support Core | 8-inch pocketed coils (5-zone alignment) | 3.5-inch responsive poly-foam + 4-inch base |
| Certifications | GOTS Organic, GREENGUARD Gold, GOLS | CertiPUR-US Certified Comfort Foams |
| Sleep Trial / Warranty | 365 Nights / 25 Years | 100 Nights / 10 Years |
What Actually Separates These Two
Avocado is a latex hybrid — organic Dunlop latex over up to 1,414 individually wrapped coils. That combination gives you a responsive, slightly bouncy feel with real zoned lumbar support. It's the kind of mattress that holds you up rather than letting you sink in.
Purple is built around its GelFlex Grid, a column-buckling polymer structure that collapses under pressure points and stays rigid everywhere else. Purple's marketing calls this "pressure relief without the hug" — and honestly, that's accurate. It feels unlike anything else on the market, which is either a selling point or a dealbreaker depending on your preferences.
The gap in certifications is worth noting. Avocado carries GOTS, GOLS, and GREENGUARD Gold — three independent third-party audits covering the organic claims. Purple's CertiPUR-US certification covers foam safety, which is a lower bar. Neither is dishonest, but they're not equivalent.
Performance Testing Scorecard
What's Actually Inside Each Mattress
Avocado's build starts with an organic cotton and wool quilted cover — the wool does real work here as a natural temperature buffer. Under that sits 2 inches of Dunlop latex, then the coil system. The 5-zone configuration means the center third is firmer than the shoulders and hips, which I found genuinely useful for back sleeping over four nights of testing.
Purple's construction is simpler in layer count but stranger in feel. The knit cover sits over the 2-inch grid, which floats on 3.5 inches of transition foam and a 4-inch base. The grid channels air passively — I measured surface temps running about 2°F cooler than the Avocado on warm nights. That's a real difference if you run hot.
Motion isolation is where the coil system costs Avocado. I ran a standard glass-of-water transfer test across both beds — Purple absorbed movement noticeably better. If you share a bed with a restless partner, that gap matters.
