What separates these two beds?

These are not interchangeable versions of the same mattress. The AS3 is an all-foam model built around Amerisleep’s Bio-Pur comfort foam and HIVE zoning. The Zoma Hybrid combines foam and pocketed coils, giving it a different support structure and a more buoyant design on paper.

Amerisleep labels the AS3 medium. Zoma rates the Hybrid 6/10, or “Luxury Firm,” on its product page. Firmness numbers are brand descriptions, not a standardized scale, so do not read 6/10 as a lab measurement or assume that one brand’s “medium” will feel identical to another’s.

For a Queen, the listed promotional prices are $1,249 for the AS3 and $974.25 for the Zoma Hybrid. That makes Zoma $274.75 less at the displayed sale prices. Their listed regular prices are $1,749 and $1,299, respectively. A sale label is not a promise that a promotion will still apply at checkout; review the cart and any code or offer conditions.

Queen-to-Queen prices by size

Both product selectors list seven sizes. The amounts below distinguish the current displayed sale price from the listed regular price; split configurations may have different totals than a single-piece size. The Zoma Hybrid’s sale prices reflect its displayed 25% promotion. Check the brand’s checkout page for the amount actually charged.

My price call: Zoma is the clear lower-cost pick at every size in the listed sale prices above. If you are shopping a Split King, check whether the selected cart is for two Twin XL mattresses or one listed split configuration and confirm the frame/base is sold separately.

How do the foams and coils change the feel?

Amerisleep describes the AS3 as a 12-inch medium mattress with a Bio-Pur memory-foam comfort layer and HIVE support. The brand says HIVE uses five support zones, with more cushioning around the shoulders and hips and firmer support beneath the back. That is useful if you are comparing an all-foam contouring feel with targeted zoning, but it is a description of the design rather than a measured result.

Zoma describes its Hybrid as a 12-inch, four-layer mattress: 2 inches of gel memory foam with Triangulex cutouts, 2 inches of responsive Reactiv foam, 7 inches of pocketed coils, and a 1-inch foam base. Its cover is described as breathable mesh made from polyester and spandex. Coils make this a different construction from the AS3; they do not establish that the Zoma will sleep cooler, isolate motion better, or have stronger edges in your bedroom.

Based on the published feel descriptions, I would start with the AS3 if you want a medium feel and with Zoma if you prefer its “Luxury Firm” label. The labels are not directly calibrated between brands. If you are between positions or sensitive to firmness, the trial policies matter more than trying to convert the two descriptions into a precise score.

• Side sleepers: both brands position these as accommodating options, but the AS3’s “medium” label may be the more obvious starting point if you want a less firm description. This is a fit recommendation based on the manufacturers’ labels, not a hands-on verdict.
• Back sleepers: either could be worth considering if the stated feel matches your preference. Zoma’s coil core is the key structural distinction; Amerisleep’s HIVE zoning is its design distinction.
• Stomach sleepers: neither is described as extra firm. If you know you need a very firm surface, I would look at a firmer model rather than assume either one will suit you.
• Combination sleepers: Zoma’s Reactiv layer is marketed as responsive, while AS3 remains an all-foam build. Neither responsiveness nor ease of changing positions was measured for this comparison.

Cooling, edge support, and motion transfer were not measured. Amerisleep describes its Refresh cover and Bio-Pur foam as cooling features; Zoma describes gel foam and breathable mesh. Treat those statements as product claims, not a head-to-head temperature test. Zoma says pocketing is intended to reduce motion transfer; we did not measure movement or edge compression.

Both brands state that their foam is CertiPUR-US certified. Amerisleep’s product materials also identify the AS3 as fiberglass-free and made in the USA from U.S. and imported components, with covers sewn in Canada. Zoma describes its mattress as made in the USA and its foam as CertiPUR-US certified; the product page also displays an OEKO-TEX badge. These certifications describe specific material or emissions standards; they are not medical endorsements or proof of comfort.

What does each 100-night trial really cost?

Both companies advertise a 100-night mattress trial and a 30-night adjustment period before initiating a return. Amerisleep says the trial begins when the mattress arrives at your home; its trial terms describe free pickup and a full refund after the mattress is collected. Zoma says a return can be requested after 30 nights and that it will help arrange pickup and refund the purchase. Both advertise free mattress returns within the contiguous U.S. on their current product/trial information.

Practical trial cost: Neither brand lists a mattress return fee in the terms reviewed for this comparison, and both describe free pickup/returns. Accessories and bases are not the same as mattresses: Amerisleep says pillows, sheets, and bedding accessories are final sale, and foundations/adjustable bases are not refundable; Zoma says accessories, foundations, and adjustable bases are final sale under its FAQ. Do not assume add-ons inherit the mattress trial.

Zoma’s policy says discounted or free gifts may be deducted from a refund if not returned with the original order. Read bundle terms before paying.

Warranty terms: compare the threshold and the fine print

Amerisleep lists a 20-year limited mattress warranty split into 10 years of full replacement coverage and 10 prorated years. Its warranty page says visible indentation must exceed 1.5 inches in the middle sleep area to qualify under that provision; corners and edges are excluded, and the indentation cannot be caused by the foundation. During the prorated second decade, Amerisleep says the replacement cost is 50% of the original purchase price, with shipping, labor, and other associated costs the customer’s responsibility.

Zoma lists a 10-year full-replacement warranty for workmanship and structural defects. Its warranty also gives a visible indentation threshold greater than 1.5 inches in the center, excluding corners and edges and sag caused by the foundation. Zoma says it may cover the replacement mattress, but the customer may be responsible for labor and shipping; it does not provide haul-away of a defective mattress.

Both warranties require an appropriate support surface. Amerisleep specifies that third-party slats must be no more than 2.75 inches apart; a box spring needs a 0.75-inch moisture-resistant plywood sheet over the full surface. Zoma’s warranty gives the same 2.75-inch maximum for slat spacing and requires 0.75-inch plywood over a box spring. Zoma’s FAQ gives a three-inch slat spacing recommendation, while its warranty states 2.75 inches; follow the stricter warranty condition if preserving coverage matters.

Both warranties are limited to the original purchaser and have exclusions for damage, stains, improper foundations, or unsanitary condition. A longer warranty does not mean every comfort change is covered. Amerisleep says normal softening is not covered; Zoma likewise excludes normal wear and an increase in softness. Keep the receipt and, if you use a separate foundation, retain evidence of the setup.

Delivery, setup, and day-one details

Amerisleep says the AS3 ships within 3–7 business days, then typically takes 1–5 more days in transit. Zoma says its Hybrid usually leaves in 3–7 business days and arrives 1–5 days after shipment. Both advertise free curbside shipping in the contiguous U.S.

Neither product listing describes free in-home setup as part of standard mattress delivery. Plan to move the boxed mattress into the room and arrange the bed frame or foundation separately. Both brands say their mattresses can work with adjustable bases; this comparison did not test that compatibility.

For support, do not place either mattress on widely spaced slats or a springy box spring without the required solid board. Amerisleep’s current product information says non-Amerisleep slats should be 2.75 inches apart or less. Zoma’s warranty also says 2.75 inches or less, even though its FAQ uses a three-inch recommendation. The warranty wording is the safer limit to follow for either model.

Who should buy the AS3—and who should not?

• Choose AS3 if you want an all-foam mattress, a medium label, HIVE zoned-support design, and a 20-year warranty with the last decade prorated.
• Skip AS3 if you specifically want pocketed coils, want to spend less at the displayed sale prices, or are searching for an extra-firm feel.
• Choose Zoma Hybrid if you want a coil-and-foam construction, a Luxury Firm label, and a lower listed price while keeping a 100-night trial.
• Skip Zoma if you want the longer stated warranty term or prefer a medium rather than the brand’s Luxury Firm description.

My overall pick is the AS3 for someone choosing primarily by published medium feel and warranty length. That preference does not erase Zoma’s value advantage: a Queen is listed $274.75 lower at the current displayed sale prices. If your budget or coil preference is the deciding factor, the Zoma Hybrid is a sensible alternative rather than a consolation pick.

Frequently asked questions

Is Amerisleep AS3 softer than Zoma Hybrid?

Amerisleep calls the AS3 medium; Zoma calls its Hybrid Luxury Firm and rates it 6/10. Those labels suggest different intended feels, but they are not directly comparable measurements. Your best guide is your own preference and the trial terms.

Which mattress costs less in Queen?

The displayed Queen sale price is $974.25 for Zoma Hybrid and $1,249 for AS3, a $274.75 gap. The listed regular prices are $1,299 and $1,749. Promotions can change, so confirm the amount in the checkout cart.

Do both have a 100-night sleep trial?

Yes. Both brands advertise a 100-night trial and request at least 30 nights of use before initiating a return. Both describe free mattress pickup/returns in the contiguous U.S.; check the policy for your delivery location and any bundled products.

Which mattress has the longer warranty?

Amerisleep lists a 20-year limited warranty, with the final 10 years prorated. Zoma lists a 10-year full-replacement warranty. Both use a greater-than-1.5-inch visible central indentation threshold in their warranty terms, subject to exclusions and foundation requirements.

Is Zoma Hybrid better for people who want bounce?

Zoma’s hybrid construction includes pocketed coils beneath foam, while the AS3 is all foam. That structural difference may make Zoma the more relevant model to consider if you specifically want a coil core, but bounce was not measured in this comparison.

Can I use either mattress on an adjustable base?

Both brands state that their mattresses are compatible with adjustable bases. That is the manufacturers’ stated compatibility, not a test conducted for this comparison. Check the base’s dimensions and support instructions before ordering.

Do either of these mattresses contain fiberglass?

Amerisleep describes the AS3 as fiberglass-free. Zoma’s product page also identifies its hybrid mattress as fiberglass-free. Follow each brand’s care and warranty instructions rather than opening or altering the mattress cover.

Which one should I buy?

I’d pick AS3 if you want a medium all-foam mattress and value its longer warranty. I’d pick Zoma Hybrid if you want pocketed coils and a lower displayed Queen price. Neither brand’s claims substitute for your own fit preference, so read the return details before purchase.
