For active cooling: Eight Sleep Pod Pro is the most effective but costs $2,000+. Saatva Solaire offers adjustable air support at $2,995.<\/div>\n<\/div>\n<div style=\"border-bottom:1px solid #e8e0d0;padding:16px 0;\">\n<div style=\"font-weight:700;margin-bottom:6px;\">Does gel memory foam actually keep you cool?<\/div>\n<div style=\"color:#3a3a3a;\">Gel memory foam sleeps cooler than traditional memory foam initially, but the cooling effect fades as gel particles complete their heat-cycling over 2\u20133 years. Structural solutions (coils, latex) provide consistent cooling throughout the mattress&#8217;s life.<\/div>\n<\/div>\n<div style=\"border-bottom:1px solid #e8e0d0;padding:16px 0;\">\n<div style=\"font-weight:700;margin-bottom:6px;\">Is latex good for hot sleepers?<\/div>\n<div style=\"color:#3a3a3a;\">Yes \u2014 natural Talalay latex has an open-cell structure that inherently breathes. Saatva&#8217;s Latex Hybrid combines latex comfort with coil base cooling for an excellent result for hot sleepers.<\/div>\n<\/div>\n<div style=\"border-bottom:1px solid #e8e0d0;padding:16px 0;\">\n<div style=\"font-weight:700;margin-bottom:6px;\">What else can hot sleepers do besides a cooling mattress?<\/div>\n<div style=\"color:#3a3a3a;\">Lower room temperature to 65\u201368\u00b0F; use percale cotton or linen sheets (not polyester); choose a breathable pillow (latex or buckwheat); consider a cooling mattress pad\/topper if replacing a mattress isn&#8217;t feasible.<\/div>\n<\/div>\n<\/div>\n<div itemscope itemtype=\"https:\/\/schema.org\/Article\"><meta itemprop=\"headline\" content=\"Best Cooling Mattress 2026\"\/><meta itemprop=\"datePublished\" content=\"2026-04-29\"\/><meta itemprop=\"dateModified\" content=\"2026-04-29\"\/><\/p>\n<div itemprop=\"author\" itemscope itemtype=\"https:\/\/schema.org\/Organization\"><meta itemprop=\"name\" content=\"World Sleep Almanac Editorial Team\"\/><\/div>\n<div itemprop=\"publisher\" itemscope itemtype=\"https:\/\/schema.org\/Organization\"><meta itemprop=\"name\" content=\"World Sleep Almanac\"\/><\/div>\n<\/div>\n<div itemscope itemtype=\"https:\/\/schema.org\/BreadcrumbList\">\n<div itemprop=\"itemListElement\" itemscope itemtype=\"https:\/\/schema.org\/ListItem\"><meta itemprop=\"position\" content=\"1\"\/><\/p>\n<div itemprop=\"item\" itemscope itemtype=\"https:\/\/schema.org\/WebPage\"><meta itemprop=\"name\" content=\"World Sleep Almanac\"\/><meta itemprop=\"id\" content=\"https:\/\/journee-mondiale.com\/en\/\"\/><\/div>\n<\/div>\n<div itemprop=\"itemListElement\" itemscope itemtype=\"https:\/\/schema.org\/ListItem\"><meta itemprop=\"position\" content=\"2\"\/><\/p>\n<div itemprop=\"item\" itemscope itemtype=\"https:\/\/schema.org\/WebPage\"><meta itemprop=\"name\" content=\"Mattress Guides\"\/><meta itemprop=\"id\" content=\"https:\/\/journee-mondiale.com\/en\/mattress-reviews\/\"\/><\/div>\n<\/div>\n<div itemprop=\"itemListElement\" itemscope itemtype=\"https:\/\/schema.org\/ListItem\"><meta itemprop=\"position\" content=\"3\"\/><\/p>\n<div itemprop=\"item\" itemscope itemtype=\"https:\/\/schema.org\/WebPage\"><meta itemprop=\"name\" content=\"Best Cooling Mattress 2026\"\/><meta itemprop=\"id\" content=\"https:\/\/journee-mondiale.com\/en\/best-cooling-mattress-2026\/\"\/><\/div>\n<\/div>\n<\/div>\n<p><!-- JM_BATCH19_ENRICH_V1 --><\/p>\n<aside style=\"margin:40px 0;padding:22px 26px;border-left:3px solid #1a1a1a;background:#faf8f3;font-family:Georgia,'Times New Roman',serif;\">\n<div style=\"font-size:11px;letter-spacing:0.18em;text-transform:uppercase;color:#6a5a3a;margin-bottom:10px;font-family:system-ui,sans-serif;\">Related Reading<\/div>\n<ul style=\"margin:0;padding-left:20px;font-size:0.97em;line-height:1.85;\">\n<li><a href=\"\/en\/saatva-classic-review-2026\/\">Saatva Classic Review \u2014 Almanac 9.1\/10<\/a><\/li>\n<li><a href=\"\/en\/saatva-solaire-review-2026\/\">Saatva Solaire Review 2026<\/a><\/li>\n<li><a href=\"\/en\/best-mattress-hot-sleepers-2026\/\">Best Mattress for Hot Sleepers 2026<\/a><\/li>\n<li><a href=\"\/en\/saatva-vs-eight-sleep-2026\/\">Saatva vs Eight Sleep 2026<\/a><\/li>\n<li><a href=\"\/en\/saatva-latex-hybrid-review-2026\/\">Saatva Latex Hybrid Review 2026<\/a><\/li>\n<\/ul>\n<\/aside>\n<p><!-- \/JM_BATCH19_ENRICH_V1 --><br \/>\n<!-- JM_BOOST_V1_CLOSE --><\/p>\n","protected":false},"excerpt":{"rendered":"<p>JM Editorial Team \u00b7 World Sleep Almanac \u00b7 Updated April 29, 2026 \u00b7 10 min read \u00b7 Mattress Guides Quick Verdict Best for: Passive structural cooling: Saatva Classic (coils) and Latex Hybrid.
