The AS3 is a single medium-feel, 12-inch model with a Refresh cooling cover. The AS6 Black Series is a 14-inch mattress offered in three firmness levels, from Plush Soft to Firm, with a triple-cooling system built into the cover and foam layers. If you want a simple, balanced medium feel, the AS3 is the straightforward pick. If you want to choose your firmness and you sleep hot, the AS6 Black Series is the one to look at.<\/p>\n<p>Both mattresses carry the same Amerisleep trial and warranty terms: a 100-night sleep trial, free shipping and returns, and a 20-year warranty. Both are fiberglass-free. The differences are in the construction, the cooling stack, and the firmness options, and those differences are what this comparison walks through.<\/p>\n<div class=\"jm-cta jm-pick\" style=\"border:2px solid #14213d;border-radius:12px;padding:18px 20px;margin:20px 0;background:#f8fafc;\">\n<img decoding=\"async\" src=\"https:\/\/saatva.imgix.net\/products\/saatva-classic\/lifestyle\/standard\/11.5\/saatva-classic-lifestyle-standard-11.5-16-9.jpg?w=768\" alt=\"Saatva Classic mattress in a bedroom\" style=\"float:right;width:160px;max-width:40%;margin:0 0 10px 14px;border-radius:8px;\" \/><\/p>\n<p style=\"margin:0 0 6px;font-size:13px;letter-spacing:.06em;text-transform:uppercase;color:#d08a1a;\"><strong>A strong alternative<\/strong><\/p>\n<p style=\"margin:0 0 8px;font-size:20px;color:#14213d;\"><strong>Saatva Classic<\/strong> an innerspring option with three comfort levels and a dual-coil base<\/p>\n<ul style=\"margin:0 0 12px 18px;\">\n<li><strong>365-night home trial<\/strong><\/li>\n<li>Free white-glove delivery and old-mattress removal<\/li>\n<li><strong>Lifetime warranty<\/strong><\/li>\n<li>Available in 11.5-inch and 14.5-inch heights<\/li>\n<\/ul>\n<p><a href=\"https:\/\/saatva.prf.hn\/click\/camref:1100lrIix\/pubref:jm-amerisleep-as3-vs-as6-2026__pick__saatva__2026\/destination:https%3A%2F%2Fwww.saatva.com%2Fmattresses%2Fsaatva-classic\" rel=\"nofollow sponsored noopener\" target=\"_blank\" style=\"display:inline-block;background:#d08a1a;color:#fff;font-weight:700;padding:12px 24px;border-radius:8px;text-decoration:none;\">Check today&#8217;s Saatva price &rarr;<\/a>\n<\/div>\n<h2>What is the main difference between the Amerisleep AS3 and the Amerisleep AS6 Black Series?<\/h2>\n<p>The main difference is that the Amerisleep AS3 comes in one medium feel at a 12-inch profile, while the Amerisleep AS6 Black Series is a 14-inch mattress offered in three firmness levels: Plush Soft at 3\/10, Luxury Firm at 7\/10, and Firm at 8\/10 on Amerisleep&#8217;s own firmness scale, where 1 is softest and 10 is firmest. The AS6 carries a three-part cooling system: a CryoCool cover, a TitanAir layer, and ArcticWave cooling bands.<\/p>\n<p>The AS3 is built around plant-based Bio-Pur memory foam with HIVE technology for targeted support, and it offers a Refresh cooling cover that the brand says keeps the sleeping surface about 7 degrees cooler over an eight-hour night. The AS6 Black Series adds a CryoCool cover, a TitanAir titanium-infused memory foam layer, and ArcticWave mineral-infused cooling bands, which the brand describes as its Triple-Cooling Technology.<\/p>\n<p>In short, the AS3 is the simpler, single-choice model. The AS6 Black Series is the more configurable, more heavily cooled model, and it stands 2 inches taller.<\/p>\n<h2>How do the Amerisleep AS3 and Amerisleep AS6 Black Series feel and support different sleepers?<\/h2>\n<p>The Amerisleep AS3 has one stated feel: medium, described by the brand as balanced comfort and support suitable for all sleeping styles. The Amerisleep AS6 Black Series gives you three feels to choose from, and the brand assigns each a specific sleeper profile: Plush Soft for side sleepers who want deep pressure relief, Luxury Firm for couples with different firmness preferences and back sleepers, and Firm for back sleepers seeking spinal alignment.<\/p>\n<p>On Amerisleep&#8217;s firmness scale, where 1 is softest and 10 is firmest, the AS6 Plush Soft sits at 3\/10, the Luxury Firm at 7\/10, and the Firm at 8\/10. The AS3 is listed simply as medium, with no number given on that scale.<\/p>\n<p>Both mattresses use Bio-Pur memory foam, which the brand describes as open-cell and more breathable and responsive than traditional memory foam, snapping back to shape in seconds so you do not sink in uncomfortably. If you want one medium feel and do not want to choose, the AS3 covers that. If you know you want a specific firmness, the AS6 Black Series is the one that lets you pick.<\/p>\n<h2>Side-by-side: Amerisleep AS3 vs Amerisleep AS6 Black Series<\/h2>\n<table>\n<thead>\n<tr>\n<th>Feature<\/th>\n<th>Amerisleep AS3<\/th>\n<th>Amerisleep AS6 Black Series<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>Feel<\/td>\n<td>Medium<\/td>\n<td>Customizable: Plush Soft, Luxury Firm, Firm<\/td>\n<\/tr>\n<tr>\n<td>Profile height<\/td>\n<td>12-inch<\/td>\n<td>14-inch<\/td>\n<\/tr>\n<tr>\n<td>Cooling<\/td>\n<td>Refresh Cooling Technology, Bio-Pur<\/td>\n<td>CryoCool cover, TitanAir layer, ArcticWave bands<\/td>\n<\/tr>\n<tr>\n<td>Material options<\/td>\n<td>All Foam or Hybrid (Foam + Coils)<\/td>\n<td>Memory foam construction<\/td>\n<\/tr>\n<tr>\n<td>Firmness scale<\/td>\n<td>Medium, no number listed<\/td>\n<td>3\/10, 7\/10, or 8\/10 depending on comfort level<\/td>\n<\/tr>\n<tr>\n<td>Sleep trial<\/td>\n<td>100-night risk-free<\/td>\n<td>100-night risk-free<\/td>\n<\/tr>\n<tr>\n<td>Warranty<\/td>\n<td>20-year<\/td>\n<td>20-year<\/td>\n<\/tr>\n<tr>\n<td>Shipping<\/td>\n<td>Free shipping and returns<\/td>\n<td>Free shipping and returns<\/td>\n<\/tr>\n<tr>\n<td>Certifications<\/td>\n<td>Fiberglass-free, non-toxic<\/td>\n<td>CertiPUR-US certified foams, OEKO-TEX Standard 100<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>The table covers the specs both brands publish. Where a figure is not listed, it is left blank rather than estimated. Neither mattress&#8217;s price appears in the material reviewed here, so this comparison draws no conclusion from price.<\/p>\n<h2>Which mattress sleeps cooler, the Amerisleep AS3 or the Amerisleep AS6 Black Series?<\/h2>\n<p>The Amerisleep AS6 Black Series carries more cooling technology on paper than the Amerisleep AS3. The AS6 lists three cooling components: a CryoCool cover for an immediate cool-to-touch sensation, a TitanAir titanium-infused memory foam layer that disperses heat, and ArcticWave mineral-infused cooling bands that the brand says maintain temperature throughout the night. The AS3 lists a Refresh cooling cover and Bio-Pur open-cell foam.<\/p>\n<p>Amerisleep states that the AS3&#8217;s Refresh cover keeps the sleeping surface on average 7 degrees cooler over an eight-hour night. The AS6&#8217;s cooling stack is described as Triple-Cooling Technology, but no equivalent temperature figure is published for it.<\/p>\n<p>If you sleep hot and want the most cooling components named by the brand, the AS6 Black Series is the one with the longer list. If you want a stated temperature figure and a simpler cooling setup, the AS3 publishes one. Both mattresses use the same Bio-Pur open-cell foam, which the brand says allows more air to circulate than traditional foam.<\/p>\n<h2>Who should buy the Amerisleep AS3?<\/h2>\n<p>The Amerisleep AS3 is the right choice if you want one medium feel that the brand says works for all sleeping styles, and you do not want to pick between firmness levels. It is also the pick if a 12-inch profile suits your bed setup better than a 14-inch one, or if you want the option of an all-foam or a hybrid (foam plus coils) version of the same mattress. The AS3 is also the model to consider if you want a published cooling figure: Amerisleep states the Refresh cover keeps the surface about 7 degrees cooler over an eight-hour night.<\/p>\n<p>The AS3 was voted Newsweek Readers&#8217; Choice Best Mattress of 2026.<\/p>\n<p>Choose the AS3 if you are a combination sleeper who changes positions at night and wants a balanced medium feel rather than a specific firmness. If you already know you want a plush or a firm feel, the AS3&#8217;s single medium option may not match what you are after, and the AS6 Black Series gives you that choice.<\/p>\n<h2>Who should buy the Amerisleep AS6 Black Series?<\/h2>\n<p>The Amerisleep AS6 Black Series is the right choice if you want to choose your firmness level and you sleep hot. The AS6 offers Plush Soft at 3\/10, Luxury Firm at 7\/10, and Firm at 8\/10 on Amerisleep&#8217;s firmness scale, where 1 is softest and 10 is firmest, so you can match the mattress to how you sleep rather than adapting to one feel.<\/p>\n<p>The AS6 Black Series stands at a 14-inch profile, 2 inches taller than the AS3. Its foams are CertiPUR-US certified and its materials are OEKO-TEX Standard 100 certified, confirmed made to CertiPUR-US limits on content and emissions including fiberglass.<\/p>\n<p>Choose the AS6 Black Series if you are a side sleeper who wants deep pressure relief, the Plush Soft version is the one the brand designs for that. If you are a back sleeper who wants spinal alignment, the Firm version at 8\/10 is the one the brand points to. If you and a partner disagree on firmness, the Luxury Firm is the version the brand recommends for couples.<\/p>\n<div class=\"jm-cta\" style=\"border:1px solid #f0d9a8;background:#fffdf7;border-radius:10px;padding:16px 20px;margin:22px 0;\">\n<strong style=\"color:#14213d;\">Still deciding?<\/strong> If you want a mattress with three comfort levels and a dual-coil base rather than an all-foam build, the Saatva Classic is worth a look.<br \/>\n<a href=\"https:\/\/saatva.prf.hn\/click\/camref:1100lrIix\/pubref:jm-amerisleep-as3-vs-as6-2026__mid__saatva__2026\/destination:https%3A%2F%2Fwww.saatva.com%2Fmattresses%2Fsaatva-classic\" rel=\"nofollow sponsored noopener\" target=\"_blank\" style=\"font-weight:700;color:#d08a1a;\">See the Saatva Classic price in your size &rarr;<\/a>\n<\/div>\n<h2>What are the trial, warranty, and shipping terms for both mattresses?<\/h2>\n<p>The AS6&#8217;s warranty is described as covering material durability and craftsmanship. The AS3 is fiberglass-free and non-toxic.<\/p>\n<p>Because the trial and warranty terms are identical, they do not help you choose between the two. The decision comes down to feel, height, and cooling. The Saatva Classic carries a 365-night home trial, while the Amerisleep models come with a 100-night trial.<\/p>\n<h2>Who should not buy either the Amerisleep AS3 or the Amerisleep AS6 Black Series?<\/h2>\n<p>Neither the Amerisleep AS3 nor the Amerisleep AS6 Black Series is the right pick if you want an innerspring or latex feel rather than a memory foam feel. Both are built around Bio-Pur memory foam, and while the AS3 offers a hybrid version with coils, the AS6 Black Series is listed as a memory foam construction. If you want a coil feel with a pillow top, the Saatva Classic is an innerspring mattress with a 3-inch Euro pillow top and a dual-coil base of triple-tempered recycled carbon steel coils.<\/p>\n<p>Neither mattress is also the pick if you want a mattress with a published price in the size you need, since neither price appears in the material reviewed here. Check the brand&#8217;s current listing for the size you want before you decide.<\/p>\n<p>Finally, if you want a mattress with a trial longer than 100 nights, both Amerisleep models carry the same 100-night trial, and the Saatva Classic carries a 365-night home trial.<\/p>\n<h2>How does the Saatva Classic compare as an alternative?<\/h2>\n<p>The Saatva Classic is an innerspring mattress with a 3-inch Euro pillow top, a dual-coil design of triple-tempered recycled carbon steel coils, and patented Lumbar Zone technology. It comes in three comfort levels: Plush Soft at 3\/10, Luxury Firm at 5-7\/10, and Firm at 8\/10 on Saatva&#8217;s scale, where 1 is softest and 10 is firmest. It is available in 11.5-inch and 14.5-inch heights.<\/p>\n<p>The Saatva Classic carries a 365-night home trial and a lifetime warranty, both longer than the 100-night trial and 20-year warranty on the Amerisleep AS3 and AS6 Black Series. Saatva includes free white-glove delivery with in-room setup and free removal of your old mattress. Saatva&#8217;s foams are CertiPUR-US certified and the mattress is endorsed by the American Chiropractic Association.<\/p>\n<p>If you want a coil feel rather than a foam feel, or a longer trial and warranty, the Saatva Classic is the alternative to consider. If you want an all-foam mattress with a specific firmness and a heavy cooling stack, the Amerisleep AS6 Black Series is the better fit, and the Amerisleep AS3 is the simpler middle ground.<\/p>\n<p>For more on foam options, see our <a href=\"\/en\/best-memory-foam-mattress-2026\">best memory foam mattresses<\/a> and our <a href=\"\/en\/best-hybrid-mattress-2026\">best hybrid mattresses<\/a>.<\/p>\n<div class=\"jm-cta\" style=\"border:2px solid #14213d;border-radius:12px;padding:18px 20px;margin:20px 0;background:#f8fafc;\">\n<p style=\"margin:0 0 6px;font-size:13px;letter-spacing:.06em;text-transform:uppercase;color:#d08a1a;\"><strong>Our verdict<\/strong><\/p>\n<p style=\"margin:0 0 10px;color:#14213d;\"><strong>The Amerisleep AS6 Black Series wins this comparison for sleepers who want a specific firmness and the brand&#8217;s full cooling stack, while the Amerisleep AS3 is the simpler pick for anyone who wants one balanced medium feel.

The AS6 Black Series is available at 3\/10, 7\/10, or 8\/10 on Amerisleep&#8217;s firmness scale, where 1 is softest and 10 is firmest. The AS3 is listed as medium with no number on that scale. So the Plush Soft AS6 is softer than a medium feel, and the Firm AS6 at 8\/10 is firmer.<\/p>\n<h3>Do both mattresses sleep cool?<\/h3>\n<p>Both use Bio-Pur open-cell memory foam, which the brand says allows more air to circulate than traditional foam. The AS3 adds a Refresh cooling cover, and Amerisleep states the surface stays on average 7 degrees cooler over an eight-hour night. The AS6 Black Series adds a CryoCool cover, a TitanAir layer, and ArcticWave cooling bands, which the brand calls Triple-Cooling Technology.<\/p>\n<h3>Can I try either mattress at home before deciding?<\/h3>\n<p>Both the Amerisleep AS3 and the Amerisleep AS6 Black Series carry a 100-night sleep trial with free shipping and returns. If 100 nights feels short for your decision, the Saatva Classic carries a 365-night home trial.<\/p>\n<h3>Which is better for side sleepers?<\/h3>\n<p>The Amerisleep AS6 Black Series in Plush Soft is the version the brand designs for side sleepers, describing it as delivering deep pressure relief at 3\/10 on its firmness scale. The AS3 is a medium feel that the brand says works for all sleeping styles, so it can work for side sleepers, but it does not offer a dedicated plush option.<\/p>\n<p>For more on side-sleeper options, see our <a href=\"\/en\/best-latex-mattress-2026\">best latex mattresses<\/a> and our <a href=\"\/en\/best-organic-mattress-2026\">best organic mattresses<\/a>.<\/p>\n<h3>Is the Saatva Classic a good alternative if I want coils?<\/h3>\n<p>The Saatva Classic is an innerspring mattress with a dual-coil design of triple-tempered recycled carbon steel coils and a 3-inch Euro pillow top, available in 11.5-inch and 14.5-inch heights. It carries a 365-night home trial and a lifetime warranty, both longer than the terms on the Amerisleep AS3 and AS6 Black Series. It comes in Plush Soft at 3\/10, Luxury Firm at 5-7\/10, and Firm at 8\/10 on Saatva&#8217;s scale.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>The Amerisleep AS3 and the Amerisleep AS6 Black Series are two mattresses from the same brand, and they split on one main axis: how much cooling technology and how much firmness choice you want.
