Avocado offers two mattresses exclusively through Costco for members: the Organic 11" Hybrid Mattress (Tighttop) and the Organic 13" Pillow-Top Hybrid Mattress. This article explains how they differ from the Avocado Green Mattress — the best-selling, most award-winning model — and the Avocado Eco Organic Mattress available on our website.
What they all have in common
All four mattresses are built on the same certified organic foundation and share the same commitment to verified material safety:
8-inch fabric-encased coil support system (coil counts and zones vary)
4 handles for easy repositioning
Certified under GOTS, OEKO-TEX® Standard 100 Class I, MADE SAFE®, and EWG Verified®
Use GOLS organic latex, made with 95% or more certified organic material
Where they differ
Comfort layers and height
Model | Total Height | Latex Construction | Feel(s) |
~10" | 2" organic Dunlop latex (top) | Medium (~5/10) | |
Green Mattress | 5 Height Options: Ultra Plush (~15.5") | 2" organic Dunlop latex (top) + 1" (bottom) | 5 Firmness Options: |
~11" | 2" organic Dunlop latex (top) + 0.75" (bottom) | Medium (~5/10) | |
~13" | 4" organic Dunlop latex + 0.75" (bottom) | Medium-Soft (~4/10) |
Coil counts, zoning, and needle tufting
The Green Mattress is the most fully featured of the four in terms of internal construction — with ergonomic coil zoning and hand needle-tufting. The other three models vary in one or both of these details.
Model | Coil Zoning | Coil Counts |
Eco Organic Mattress | Reinforced perimeter only | Up to 1,000 fabric-encased coils. |
Green Mattress | 3 interior zones + 2 head/foot zones + 2 perimeter zones (7 total) | Up to 2,112 fabric-encased coils in Extra Firm; Up to 1,379 in Medium, Firm, Plush, and Ultra Plush. |
Costco Tighttop | Reinforced perimeter only | Up to 1,000 fabric-encased coils. |
Costco Pillow-Top | Reinforced perimeter only | Up to 1,000 fabric-encased coils. |
Pro Tip: More coils mean more precise contouring and greater long-term durability. Dedicated support zones provide targeted support across different body regions — something a single-zone coil system cannot replicate.
Model | Needle Tufted by Hand |
Eco Organic Mattress | No |
Green Mattress | Yes, up to 24 locations |
Costco Tighttop | Yes, up to 24 locations |
Costco Pillow-Top | Yes, up to 24 locations |
Pro Tip: Hand needle-tufting secures comfort layers without chemical adhesives, helping maintain long-term structural integrity. It's a hallmark of the traditional bedmaker's craft.

Which should I choose?
Eco Organic Mattress — A straightforward, no-compromise certified organic mattress at an accessible price point, without needle tufting or coil zoning. Best for those who want Avocado's material standards in a simpler construction, and at an affordable price.
Green Mattress — Our best-selling and most versatile model, with ergonomic zoning, needle tufting, and five firmness options. Ideal if you want a tailored feel or sleep with a partner who has different preferences. This is NYT/Wirecutter's "Best Latex Mattress," Recommended by Consumer Reports®, and Good Housekeeping® "Best Organic Mattress."
Costco Tighttop (11") — Similar in design to our Eco and Green Tighttop, but with fewer coils and without ergonomic zones. A good fit for back and stomach sleepers who want a medium feel.
Costco Pillow-Top (13") — Similar height to the Green Plush Pillowtop, but with fewer coils and without ergonomic zones. Best for side sleepers or anyone who prefers a softer, more cushioned feel.
Why Avocado partners with Costco
Certified organic mattresses have historically cost more than conventional polyurethane foam alternatives — and for many families, a trusted retailer like Costco is simply where they shop for big purchases. Our Costco partnership is about meeting those families where they are. Costco's membership model gives us access to millions of households actively looking for better products, and that scale allows us to bring certified organic sleep to a broader audience than we could reach on our own. Every Avocado mattress sold through Costco is built to the same certified organic standard — the same GOLS organic latex, the same GOTS organic certification, the same materials as every mattress we make. Wider access to genuinely certified products is good for families, and good for the organic supply chains that depend on demand growing at scale.
