Amerisleep AS3 vs Serta iComfortPro Level Two Plush: Which Fits You?

• Amerisleep AS3 pros: medium all-foam feel, 100-night trial, free returns, 20-year warranty.
• Amerisleep AS3 cons: not the best match if you specifically want a plush surface; the Queen price does not establish prices for other sizes.
• Serta Level Two Plush pros: plush feel, responsive latex-forward design, and a 100-Day In-Home Trial.
• Serta Level Two Plush cons: its $2,299 listed configuration is not identified as Queen, and Serta's official pages conflict on delivery and haul-away charges.

This is a model-to-model comparison: the all-foam AS3, not the separate AS3 Hybrid, against Serta's iComfortPro Level Two Plush, not the Firm or Plush Pillow Top. For the broader lineup comparison, read our Amerisleep vs Serta comparison.

How the two mattresses compare at a glance

Use the feel and service terms as your shortlist, then compare the full SKU name and checkout total. A retailer's Serta return policy can differ from Serta.com's terms. The trial and warranty are not the same promise: one is a return window, the other is limited protection against covered defects.

What are you getting inside each mattress?

The AS3 is 12 inches tall and uses Amerisleep's Bio-Pur memory foam over its HIVE support system. Amerisleep describes Bio-Pur as plant-based memory foam and HIVE as zoned support. The straightforward takeaway: the AS3 is an all-foam bed with a medium feel and a more structured support layer beneath the comfort foam. Amerisleep also lists the AS3 as fiberglass-free.

The Serta iComfortPro Level Two Plush is part of Serta's all-foam iComfortPro family. Serta describes the collection around five support zones, naturally-derived latex foam, cooling materials, and responsive comfort. The specific Plush model is the softer Level Two choice; the related Ambrose Plush is listed at 13 inches. Avoid transferring the specifications of the Level Two Firm or the Dartmouth Plush Pillow Top to this model. They are different configurations.

Amerisleep says the AS3 is CertiPUR-US certified and made in the USA using U.S. and imported components; its covers are sewn in Canada. Those are the AS3's published material and manufacturing statements. The Serta product information describes latex foam and five support zones but does not make a comparable certification or manufacturing-origin statement for this model.

Neither product's specifications provide a directly comparable set of foam-density figures, so density does not settle durability. Amerisleep offers a 20-year warranty for the AS3, while Serta lists a 10-year limited warranty for the iComfortPro. Amerisleep describes compressions deeper than 1.5 inches during the first 10 years as covered; Serta's warranty distinguishes a threshold of more than 3/4 inch for smooth-top mattresses and more than 1.5 inches for quilted mattresses. These are defect thresholds, not comfort guarantees. Keep the required foundation and proof-of-purchase terms in view.

Which one feels better for your sleeping position?

Side sleepers

Side sleepers who want a soft, cushioned surface: start with the Serta Level Two Plush. Its plush designation points toward more cushioning than the AS3's medium feel. If you prefer balanced support or worry about sinking too deeply, consider the AS3. Body shape and comfort preference change how firmness feels, so use the home trial rather than treating a firmness label as a personal-fit guarantee.

Back sleepers

Back sleepers who want a medium surface: the AS3 is the more straightforward fit to investigate. Its HIVE zoning is designed to vary support across the mattress. The Serta Plush may suit back sleepers who prefer a cushioned feel; if you want a less-sinking surface, compare the Level Two Firm instead. That is a different model, not a hidden setting of the Plush.

Stomach sleepers

Stomach sleepers who need a firm, level platform: neither mattress is an automatic recommendation. A plush surface can feel too yielding, while the AS3 is medium rather than firm. If you already know you prefer firm support, look at a firmer configuration instead of choosing Serta Plush for its cooling features. The five-zone layout does not make the Plush a firm mattress.

Combination sleepers

Combination sleepers switching between back and side: the AS3's medium feel is the more balanced starting point if you do not want a pronounced plush sink. Serta's latex-forward design may appeal if you like buoyancy, though its softer surface can feel less stable when changing positions. Test each sensation in person if possible, then use the written trial terms as your fallback.

Cooling, edge support, and movement: what can you actually compare?

Amerisleep lists Refresh Cooling Technology on the AS3 and describes Bio-Pur as cooling memory foam. Serta describes the iComfortPro with cool-to-the-touch fabric and latex-based cooling features. Both brands make cooling claims, but neither means the mattress will keep every hot sleeper comfortable through every season. Bedding, room temperature, and personal heat sensitivity also affect how warm a bed feels.

The AS3 is an all-foam design. The Serta Level Two Plush is also an all-foam model, not a coil hybrid. Don't infer traditional innerspring edge reinforcement from the Serta brand name or from images of other models. Neither manufacturer provides a like-for-like edge-support measurement for these exact mattresses, so there is no defensible edge winner. If you sit on the edge to dress or need the full usable sleep surface, try them in a showroom if available.

Serta says the iComfortPro design minimizes the impact of a partner's movement. Amerisleep's product details emphasize foam construction and zoned support. Neither brand provides a comparable motion-transfer test for these two exact models. Couples who are sensitive to movement should assess this during the trial rather than assume a lab result that isn't stated.

Hot sleepers: compare the two cooling-material descriptions, but choose based on the feel you want too; neither brand's claim guarantees your personal temperature overnight. Both brands say their mattresses work with adjustable bases. Amerisleep specifies that non-Amerisleep foundations should have slats no more than 2.75 inches apart; Serta does not give a comparable slat-spacing figure on the product listing, so use its warranty and foundation terms for your base.

What should you budget for each size?

Amerisleep's AS3 price selector displays the price for the size you choose; its Queen selection has been listed at $1,249 with a regular price of $1,749. Serta's Level Two Plush page displays $2,299 for a selected configuration, but does not identify that amount as the Queen price. These figures do not establish a same-size price comparison.

The Queen is the only size with a clear AS3 price in this comparison. The Serta page's displayed $2,299 amount is for a selected configuration whose size is not identified here, so do not treat it as a Queen quote or compare it directly with the AS3 Queen. Select the same size for both and compare the delivered total, including any setup or haul-away charge.

Check the Amerisleep AS3 and select your size to see its price.

Trial, returns, warranty, and delivery are not interchangeable

Amerisleep offers a 100-night sleep trial, free returns, free shipping, and a 20-year warranty for the AS3. Amerisleep lists delivery in 3–7 business days. Read the terms before ordering, especially the trial start date, any minimum break-in period, and the steps needed to arrange a return.

Serta calls its offer a 100-Day In-Home Trial and lists a 10-year limited warranty. Its Level Two Plush product listing says white-glove delivery and old-mattress removal are free. Serta's general shipping and returns policy, however, describes white-glove delivery and haul-away as paid options. The official pages conflict, so the cost of these services is unclear; review the terms shown for your exact order.

For either mattress, the written policy for the seller you actually use controls. Do not assume a retailer's Serta offer has the same minimum-use period or return fee as Serta.com.

Also considered

• Amerisleep AS3 Hybrid: worth a look if you want the AS3's medium feel with a coil-based support core; it is a different mattress from the all-foam AS3 compared here.
• Serta iComfortPro Level Two Firm: a better Serta starting point if the Plush feels too soft. Do not transfer the Plush's price or details to the Firm configuration.
• Serta iComfortPro Level Three Firm: consider it if you want a firmer feel, but compare its own specifications and trial terms before ordering.

Who should choose each mattress?

Choose the Amerisleep AS3 if you want a medium feel, an all-foam design with Bio-Pur and HIVE zoning, a 100-night trial, free returns, and a 20-year warranty. It is also the easier choice if you want one clearly described model with direct-purchase terms.

Choose the Serta iComfortPro Level Two Plush if you specifically prefer a plush surface, want latex's more responsive feel, or value Serta's advertised white-glove delivery and old-mattress removal. It may suit a side sleeper who actively wants a softer landing; Serta's product listing and general policy conflict on delivery charges.

Skip both if you need a firm feel, have a very precise edge-support requirement, or are comparing a retailer's special Serta SKU with Serta.com's direct model. Compare the exact model name, delivery route, trial, return terms, and warranty before paying. Serta's lineup uses similar names for distinct firmness and pillow-top versions; check the cart carefully.

Who should NOT buy the Amerisleep AS3?

Do not choose the AS3 if you want a distinctly plush, sink-in surface, need a firm mattress for stomach sleeping, or prefer a springy coil feel. The AS3 is a medium all-foam mattress, not a firm bed or hybrid.

Who should NOT buy the Serta Level Two Plush?

Skip this Serta if you want a medium or firm surface, need a clearly published size-by-size price before selecting a configuration, or will only order when return fees and delivery charges are unambiguous. Its Plush label is the wrong starting point for shoppers seeking a taut, firm feel.

Final verdict: AS3 wins for most online shoppers

The Amerisleep AS3 is our overall winner for online shoppers who want a medium all-foam feel and clearly stated direct-purchase trial terms. Choose Serta instead when you specifically prefer a plush, more responsive surface and have confirmed the exact configuration and checkout services.

Frequently asked questions

Is the Amerisleep AS3 better than the Serta iComfortPro Level Two Plush?

For shoppers who want a medium feel, a 100-night trial, free returns, and a 20-year warranty, the AS3 is the better fit. Serta is more appealing if you specifically want a plush feel and value its advertised in-home delivery and haul-away.

Is the Serta iComfortPro Level Two Plush a hybrid mattress?

No. The Level Two Plush is an all-foam iComfortPro configuration with latex and other foam materials. Do not confuse it with a Serta coil hybrid from a different line.

How firm is the Serta Level Two Plush?

Serta labels this configuration Plush. That is softer than a Firm version in the same Level Two family, but firmness is subjective and depends on your body and preferred sleep position.

Can I compare the two Queen prices?

The AS3 Queen price shown is $1,249 (regular price shown: $1,749). Serta's $2,299 displayed selection is not identified as Queen, so it is not a same-size comparison.

What sagging does each warranty cover?

Amerisleep describes compressions deeper than 1.5 inches as covered during its first 10 warranty years. Serta's warranty uses thresholds that depend on whether the mattress is smooth-top or quilted: more than 3/4 inch for smooth-top and more than 1.5 inches for quilted models. Check the exact warranty document and foundation requirements for your purchase.

Can I buy the AS3 in a hybrid version?

Yes. Amerisleep also sells an AS3 Hybrid, but this comparison covers the standard all-foam AS3 only. The hybrid version has a different construction and should not be treated as the same product.
