Its headline feature is a 3X cool-to-the-touch sleeping surface that helps regulate temperature throughout the whole night, paired with AlumiLast Memory Foam in the comfort layer. If heat buildup has been the reason your current mattress fails you, this is the reason to look at the Level 3 ES.<\/p>\n<p class=\"jm-cocon-haut\">This review is part of our guide to the <a href=\"https:\/\/www.journee-mondiale.com\/en\/best-cooling-mattress-2026\/\">best cooling mattresses<\/a>, where the strongest models are compared side by side.<\/p>\n<p>Beyond cooling, Restonic builds the mattress around correct spinal alignment. The brand&#8217;s exclusive technology delivers a foam-encased, 5 support zone system designed to keep the spine properly positioned, and aluminum fiber is infused into the cell structure of the foam to reinforce the cooling effect. Restonic states that AlumiLast Memory Foam delivers a cooler, more comfortable sleep surface that lasts twice as long as conventional foam.<\/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>Our pick<\/strong><\/p>\n<p style=\"margin:0 0 8px;font-size:20px;color:#14213d\"><strong>Saatva Classic<\/strong> the coil alternative if you want a traditional innerspring feel instead of foam<\/p>\n<ul style=\"margin:0 0 12px 18px\">\n<li>Available in three comfort levels and two mattress heights<\/li>\n<\/ul>\n<p><a href=\"https:\/\/saatva.prf.hn\/click\/camref:1100lrIix\/pubref:jm-restonic-djh-level-3-es-review-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>Who is the Restonic DJH Level 3 ES for?<\/h2>\n<p>The DJH Level 3 ES suits sleepers whose main complaint is a hot mattress and who want targeted support rather than a uniform feel. Restonic&#8217;s 5 support zone system, foam-encased and built into the mattress, is aimed at correct spinal alignment across the surface, which makes the model a sensible shortlist entry for back sleepers and combination sleepers who shift position during the night. The aluminum fiber infused into the foam cell structure supports the cooling claim from the inside of the material rather than from a surface treatment alone.<\/p>\n<p>It also fits shoppers who like the Drew and Jonathan Home line and want the Level 3 tier specifically. The comfort layer uses AlumiLast Memory Foam, and Restonic positions that foam as lasting twice as long as conventional foam, so buyers who plan to keep a mattress for many years have a durability claim to weigh. If you sleep hot, want zoned support, and prefer a memory foam comfort feel, the Level 3 ES is the version to look at.<\/p>\n<h2>What specifications does the DJH Level 3 ES actually carry?<\/h2>\n<p>The published specifications for the ES version center on the surface and the support system. Restonic lists a 3X cool-to-the-touch sleeping surface, AlumiLast Memory Foam in the comfort layer, aluminum fiber infused into the foam cell structure, and a foam-encased 5 support zone system for correct spinal alignment. Those are the figures the brand puts forward, and they are the ones to compare against any other mattress on your list.<\/p>\n<table>\n<thead>\n<tr>\n<th>Feature<\/th>\n<th>Restonic DJH Level 3 ES<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>Cooling surface<\/td>\n<td>3X cool-to-the-touch sleeping surface<\/td>\n<\/tr>\n<tr>\n<td>Comfort foam<\/td>\n<td>AlumiLast Memory Foam with aluminum fiber infused in the cell structure<\/td>\n<\/tr>\n<tr>\n<td>Support system<\/td>\n<td>Foam-encased, 5 support zone system<\/td>\n<\/tr>\n<tr>\n<td>Design goal<\/td>\n<td>Correct spinal alignment and temperature regulation through the night<\/td>\n<\/tr>\n<tr>\n<td>Line<\/td>\n<td>Drew and Jonathan Home, Level 3<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<h2>How does the cooling approach work on paper?<\/h2>\n<p>Restonic describes the cooling as a property of the materials rather than an add-on. The surface is rated 3X cool-to-the-touch, and the AlumiLast Memory Foam carries aluminum fiber inside the foam cell structure, which is how the brand explains the cooler sleep surface. The stated result is temperature regulation throughout the whole night, not just at lights out. For shoppers who have owned a memory foam mattress that warmed up after an hour, that combination of a cool-touch surface plus infused fiber is the specific claim to evaluate.<\/p>\n<p>Restonic also states that AlumiLast Memory Foam stays comfortable twice as long as conventional foam. Read that as a longevity statement about the comfort layer: the cooling and the cushioning are meant to hold up together rather than fade after the first season.<\/p>\n<h2>What does the 5 zone support system promise?<\/h2>\n<p>The support story is zoning. Restonic&#8217;s exclusive technology delivers a foam-encased, 5 support zone system for correct spinal alignment. Correct spinal alignment is the outcome the brand points to, and the zoning is what it credits for that result.<\/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 cooling and zoned support are your priorities, compare the DJH Level 3 ES against a coil alternative with a full home trial before you commit.<br \/>\n<a href=\"https:\/\/saatva.prf.hn\/click\/camref:1100lrIix\/pubref:jm-restonic-djh-level-3-es-review-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>How does the DJH Level 3 ES compare with the Saatva Classic?<\/h2>\n<p>These are two different constructions aimed at overlapping buyers. The Restonic DJH Level 3 ES is a foam-forward mattress with a cool-touch surface, AlumiLast Memory Foam, and a 5 zone support system. The Saatva Classic is an innerspring mattress with a 3 inch Euro pillow top, a dual-coil design of triple-tempered recycled carbon steel, and over 1,000 coils in full size and up. One leads with foam and zoning, the other with coils and a pillow top.<\/p>\n<table>\n<thead>\n<tr>\n<th>Aspect<\/th>\n<th>Restonic DJH Level 3 ES<\/th>\n<th>Saatva Classic<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>Construction<\/td>\n<td>Foam comfort layer with 5 zone support system<\/td>\n<td>Dual-coil innerspring with 3 inch Euro pillow top<\/td>\n<\/tr>\n<tr>\n<td>Cooling claim<\/td>\n<td>3X cool-to-the-touch surface, aluminum fiber in foam<\/td>\n<td>Breathable organic cotton cover, dual-coil airflow<\/td>\n<\/tr>\n<tr>\n<td>Firmness options<\/td>\n<td>Not specified for this model<\/td>\n<td>Plush Soft 3\/10, Luxury Firm 5 to 7\/10, Firm 8\/10<\/td>\n<\/tr>\n<tr>\n<td>Support focus<\/td>\n<td>Correct spinal alignment via 5 zones<\/td>\n<td>Lumbar Zone Technology, chiropractor approved<\/td>\n<\/tr>\n<tr>\n<td>Trial and delivery<\/td>\n<td>Not specified<\/td>\n<td>365-night home trial, free white-glove delivery and removal<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p><strong>Who should buy the Restonic DJH Level 3 ES:<\/strong> sleepers who want a foam comfort feel, a surface engineered to stay cool with aluminum fiber built into the foam, and a 5 zone system aimed at spinal alignment. This is the cooling option if you sleep hot, you prefer memory foam contouring, and you want zoning rather than a uniform feel across the whole mattress. It also suits shoppers already committed to the Drew and Jonathan Home line who want the Level 3 tier with AlumiLast Memory Foam.<\/p>\n<p><strong>Who should buy the Saatva Classic:<\/strong> sleepers who want a coil innerspring feel, a choice of three firmness levels including a Firm 8\/10 for stomach sleepers, and a pillow top layer. It fits couples who cannot agree on firmness, since Luxury Firm is designed for all sleep positions, and it fits buyers who value a 365-night home trial with free white-glove delivery and old-mattress removal, plus a lifetime warranty. Heavier sleepers in the 250 to 300 pound range are also explicitly served by the Firm option.<\/p>\n<h2>What do price and policies look like?<\/h2>\n<p> Check the current price with your preferred retailer before you decide, and compare the size you need rather than the entry size. The same applies to trial terms, warranty length, and delivery: confirm those with the retailer carrying the ES version, since policies follow the seller.<\/p>\n<p>For contrast, the Saatva Classic is sold direct with a published structure: a 365-night home trial, free white-glove delivery that includes in-room setup, optional old-mattress removal at no additional cost, and a lifetime warranty covering defects in workmanship and materials for as long as the original purchaser owns the mattress. If a clear, brand-backed trial and warranty matter to your decision, that is where the two shopping experiences diverge most.<\/p>\n<h2>Who should not buy the Restonic DJH Level 3 ES?<\/h2>\n<p>Skip this model if you want a coil innerspring feel. The DJH Level 3 ES is built around AlumiLast Memory Foam and a foam-encased support system, so sleepers who want the bounce and airflow of a coil unit, or a pillow top layer, should look at an innerspring instead. Stomach sleepers who need a very firm surface should also confirm firmness with the retailer, since the published material for this model does not state a firmness rating.<\/p>\n<p>Skip it too if you want to buy direct from the brand with a long home trial and a lifetime warranty attached to the checkout. Restonic&#8217;s model page describes the mattress technology, not a direct-to-consumer trial program, so buyers who need that safety net should weigh an option that publishes one. And if your main issue is motion transfer from a partner rather than heat, the cooling and zoning features are not the reason to buy this mattress.<\/p>\n<h2>Is the Saatva Classic the better alternative?<\/h2>\n<p>For many shoppers, yes, and the reason is the trial and service package rather than the foam itself. The Saatva Classic pairs a dual-coil design with a 3 inch Euro pillow top, offers three firmness levels, and carries certifications including CertiPUR-US certified foams and GREENGUARD Gold certification, plus endorsement from the American Chiropractic Association. Its Lumbar Zone Technology targets spinal alignment in any sleep position, which overlaps with what Restonic&#8217;s 5 zone system is trying to achieve.<\/p>\n<p>The Classic also gives you a 365-night home trial, free white-glove delivery with in-room setup, old-mattress removal on request, and a lifetime warranty on defects. If you value being able to sleep on a mattress for a full year before committing, and you want the brand to handle delivery and haul-away, the Saatva Classic is the alternative to put next to the DJH Level 3 ES.<\/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>Verdict<\/strong><\/p>\n<p style=\"margin:0 0 10px;font-size:17px;color:#14213d\"><strong>The Restonic DJH Level 3 ES is the cooling option for hot sleepers who want memory foam contouring and a 5 zone support system aimed at spinal alignment.<\/strong> Its 3X cool-to-the-touch surface and aluminum fiber infused foam are the two claims that define it. Choose the Saatva Classic instead if you want coils, three firmness choices, a 365-night trial, and a lifetime warranty.<\/p>\n<p><a href=\"https:\/\/saatva.prf.hn\/click\/camref:1100lrIix\/pubref:jm-restonic-djh-level-3-es-review-2026__verdict__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<div style=\"border:1px solid #14213d;border-radius:12px;padding:16px 20px;margin:22px 0;background:#f8fafc\">\n<p style=\"margin:0 0 6px;font-weight:700;color:#14213d\">World Sleep Almanac score: 7.6\/10<\/p>\n<p style=\"margin:0 0 8px;font-size:14px;color:#444\">An editorial score, not a laboratory result.
