by For most memory-foam shoppers the smarter buy is neither: the Amerisleep AS3 gives you plant-based Bio-Pur foam that sleeps cooler than Nectar and zoned HIVE support Avocado's flat latex lacks, on a 100-night trial. The Avocado Green wins if you specifically want certified-organic latex, and the Nectar Original is the budget pick under $750.
Amerisleep AS3
9.1/10
- HIVE 5-zone support firms under the lumbar and softens at the shoulders, which neither rival does
- Plant-based Bio-Pur foam runs cooler than Nectar's standard gel memory foam
- CertiPUR-US certified and made in the USA
- Suits back, side and combo sleepers between 130 and 230 lb
- Softer edges than Avocado's coil hybrid
- Sleepers over 230 lb may prefer the firmer AS5 Hybrid
The AS3 is the bed that fixes the trade-off Avocado and Nectar force on you: organic cooling without the firm, flat feel, and a memory-foam hug without the heat. That is why it is our top recommendation here.

Why the Amerisleep AS3 is our top pick
Avocado and Nectar sit at opposite ends of the market, and both leave a gap in the middle. Avocado is a firm organic latex hybrid that sleeps cool but feels too rigid for side sleepers and offers no zoned support. Nectar is an affordable memory foam bed that contours well but sleeps warm and has no lumbar zoning either.
The AS3 closes that gap. Its Bio-Pur foam is partially plant-based with an open-cell structure, so it ventilates better than the petroleum-based foam in Nectar and runs noticeably cooler in our testing. The HIVE comfort layer is split into five zones that firm under the hips and lumbar while softening at the shoulders, which is the single feature that keeps the spine neutral for back and side sleepers alike.
You also get a CertiPUR-US certified build made in the USA, a 100-night home trial, and a 20-year warranty that covers sagging over 1.5 inches. For the buyer torn between organic cooling and a foam hug, the AS3 is the bed that delivers both.
Avocado Green Mattress
8.7/10
- Certified organic latex, cotton and wool (GOLS, GOTS, GREENGUARD Gold)
- Coil hybrid sleeps cool and supports heavier bodies well
- Strong edge support and a responsive, bouncy feel
- 15 to 20 year real-world lifespan
- Too firm for most side sleepers under 150 lb
- Expensive, and motion isolation trails foam beds
If certified-organic materials are non-negotiable, the Avocado Green is the better choice and well built for the money. Just know it runs firm and rewards back and stomach sleepers more than side sleepers.
Nectar Original
8.3/10
- One of the best value all-foam beds, often under $750 queen
- Excellent motion isolation for couples and light sleepers
- Classic memory foam hug that cradles shoulders and hips
- 365-night trial and a lifetime warranty
- Sleeps warmer than latex or Bio-Pur foam
- Lifespan around 7 to 10 years and warranty coverage prorates
For a tight budget the Nectar is the easy answer: real memory foam comfort and strong motion isolation under $750. Expect it to sleep warm and to soften sooner than the other two.
Construction and materials
Avocado Green: all-natural layers
Avocado builds its flagship with certified organic materials top to bottom. The cover is organic cotton quilted with organic New Zealand wool, which provides chemical-free fire resistance and wicks moisture. Beneath it sits a 2-inch layer of GOLS-certified Dunlop latex over 8-inch pocketed coils made from recycled steel, then an organic latex base.
Total height is around 13 inches, giving the bed a substantial, premium feel. It is made in Los Angeles with latex from Arpico, and every major component carries GOLS or GOTS certification plus GREENGUARD Gold status for low emissions.
Nectar: budget memory foam
Nectar uses three foam layers in a polyester-blend cover with a quilted gel top panel. The comfort layer is 1 inch of gel memory foam over 3 inches of transition foam, on a 7-inch high-density polyfoam base. Total height is 12 inches and all foams are CertiPUR-US certified, which is a solid standard at this price even if it carries none of Avocado's organic weight.
Amerisleep AS3: Bio-Pur and HIVE
The AS3 pairs 3 inches of plant-based Bio-Pur memory foam with a HIVE transition layer over a Bio-Core support base. Bio-Pur swaps part of the petroleum for plant oils and uses an open-cell structure that breathes better than standard memory foam. The whole bed is CertiPUR-US certified and built in the USA, with a silica-based fire barrier rather than loose fiberglass.
Comfort and feel
Avocado runs firm at 7 to 8 out of 10. The latex is responsive, so you sleep on top of the bed rather than in it, and the coils add bounce that makes moving easy. That suits back and stomach sleepers but feels hard to side sleepers under 150 lb.
Nectar feels like classic memory foam at about 6.5 out of 10. The gel top layer contours within seconds and cradles the shoulders and hips, which side sleepers love, though there is little bounce and heavier sleepers may sense the base over time.
The AS3 lands at a true medium 5 out of 10 and behaves differently from both. The HIVE zones let the hips sink while holding the lumbar, so back, side and combo sleepers all stay aligned without the flat firmness of Avocado or the deep sinkage of Nectar.
Cooling performance
Latex is temperature neutral, so the Avocado Green is the coolest of the three thanks to its open latex and coil airflow. Nectar is the warmest: gel helps at the surface, but all-foam construction traps heat and hot sleepers will notice it. The AS3 sits between them, with Bio-Pur's open-cell foam venting far better than Nectar's standard memory foam while staying a true foam feel.
Motion isolation and edge support
Nectar wins motion isolation outright; memory foam absorbs movement so a restless partner barely registers. The AS3 is close behind, while Avocado's bouncy coils transmit the most motion of the three. Edge support flips the order: Avocado's reinforced coil perimeter is strongest, the AS3 is solid for an all-foam bed, and Nectar's edges compress soonest.
Durability and warranty
Latex is the most durable material here, so Avocado should hold up 15 to 20 years and carries a 25-year warranty with full coverage for the first 10 years. The AS3's 20-year warranty covers sagging over 1.5 inches, with free replacement in years 1 to 10 and a 50 percent prorated replacement after that. Nectar's lifetime warranty sounds best but prorates heavily, and the foam typically softens within 7 to 10 years.
Who should buy each mattress
- Buy the Amerisleep AS3 if you want the best all-round memory foam feel with zoned support and cooler sleep, especially as a back, side or combo sleeper between 130 and 230 lb.
- Buy the Avocado Green if certified-organic materials matter most and you sleep on your back or stomach, run hot, or weigh over 200 lb.
- Buy the Nectar Original if budget is the deciding factor and you want a classic memory foam hug with excellent motion isolation under $750.
Avocado and Nectar each solve half the problem; the Amerisleep AS3 solves both with plant-based cooling foam and HIVE zoned support on a 100-night trial. Pick Avocado only if you need certified organic latex, or Nectar only if price is the priority.
Frequently asked questions
Is Avocado Green worth the extra cost over Nectar?
For organic-focused buyers, yes. The certified materials, cooler sleep and 15 to 20 year lifespan justify the price if you can afford it. If $1,400 is a stretch, Nectar gives acceptable comfort for a quarter of the cost, but it sleeps warmer and wears out sooner.
Which mattress is best for side sleepers?
The Amerisleep AS3 is the best of the three for side sleepers because its HIVE zones soften under the shoulders while supporting the hips. Nectar is the next best on pressure relief, and Avocado is usually too firm unless you weigh over 180 lb.
Which mattress sleeps coolest?
Avocado Green sleeps coolest thanks to latex and coils. The AS3 is a close second among foam-feel beds because Bio-Pur is open-cell, and Nectar runs the warmest of the three.
How long will each mattress last?
Avocado should last 15 to 20 years, the AS3 around 10 to 12 years, and Nectar typically 7 to 10 years before the foam softens noticeably.
