9 Best Cooling Mattress Toppers of 2026

ViscoSoft built this topper around heat, and it shows in the spec sheet. The top 2 inches are copper-infused memory foam, which ViscoSoft says draws heat away from pressure points, and they sit on 2 inches of high-density memory foam for support, for 4 inches in total. Ventilated channels run through the core to move warm air out, and the cover uses phase-changing yarns that the company says react to the temperature of the room for a cool-to-the-touch feel. That cover zips off and goes in the washing machine. ViscoSoft backs the topper with a 90-day money back guarantee and a 5-year warranty, and delivery is free. A twin XL was $224.99 on sale when we checked, down from $299.95. The trade-off is depth: 4 inches of memory foam softens a bed a lot, so sleepers who want only a thin cooling layer may prefer a 2- or 3-inch option.

The Bear Pro Topper is a straightforward cooling memory foam topper: 3 inches of copper-infused foam that Bear says contours to your body while actively drawing heat away from it. On top sits a circular knit cover that Bear describes as silky and highly breathable, made to feel cool on contact, and it unzips for laundering. The foams carry CertiPUR-US certification, and the topper comes in six sizes from twin to California king, each 3 inches thick. Shipping and returns are free in the contiguous US, and it is HSA and FSA eligible. When we checked, the page showed $224.25 with the BF35 code, down from $345, which puts it close to the ViscoSoft sale price with a thinner build. Bear's own FAQ also warns that a topper will not fix a sagging mattress, which is honest advice that applies to every pick here.

Most cooling toppers are slabs of foam. Helix took a different route with a hybrid: five layers of high-density foams and supportive microcoils, 3 inches tall, under a GlacioTex cover that Helix describes as heat conductive fabric that draws heat away from the surface. You choose Luxury Plush, which Helix pitches for mattresses that are too firm, or Luxury Firm, for beds that are too soft or starting to sag. No-slip straps hold it in place, and the foams are CertiPUR-US certified with Greenguard Gold certification and no fiberglass. Helix assembles the topper in Arizona and offers a 120-night trial with free US shipping and returns. A queen was $299 with a 20% code when we checked, against a $373.75 list price. Its page shows both a limited lifetime warranty and a 1-year warranty badge, so check which applies to the topper before you order.

Tempur-Pedic sells its topper in a standard version and a cooling version, and the cooling one is an $80 upgrade. On a queen, that brings the TEMPUR-Adapt + Cooling Topper to $439 when we checked: $359 for the base topper plus $80. You get 3 inches of extra-soft TEMPUR-Material under a cool-to-the-touch performance fabric cover. Tempur-Pedic says its material is more breathable than ordinary memory foam and helps minimize heat retention, and that it is more durable, keeping its shape for years. The cover is removable, dust mite and allergen resistant, and can be washed in cold water and air dried or dried on a cool setting. The 10-year limited warranty is the longest here. Two points weigh against it: the price, and the fact that Tempur-Pedic does not accept returns on toppers, so you cannot try it and send it back.

Linenspa's gel topper is the low-cost way to try a cooler foam layer. It is 100% polyurethane memory foam infused with what Linenspa calls thousands of tiny gel beads to help capture and dissipate heat, and the company says the foam is ventilated to pull heat away from your body. You can pick a 2-, 3- or 4-inch profile, a gel or green tea infusion, and one of ten sizes, including cot, full XL and short queen, which few brands offer. The foam is CertiPUR-US certified, ships free in 1 to 3 business days, and carries a 3-year limited warranty that applies to US purchases. The entry price was $44.99 for a 2-inch cot topper when we checked, and larger sizes cost more. The compromises are clear: there is no cover, the foam is spot clean only, and its cooling depends on gel alone, without the cooling fabrics or copper that pricier picks add.

Nectar's Softer topper is a simple, thin upgrade: 2 inches of open-cell gel memory foam that Nectar says contours to ease pressure on shoulders, hips and back. For heat, Nectar points to two things, the gel-infused foam and a breathable cover with cooling yarns woven in, which it says keeps the surface from trapping heat. The foams are CertiPUR-US certified, and the topper comes in six sizes, with weights from 10 lbs for a twin to 22 lbs for a king. Nectar sells it with a 100-night home trial and free shipping and returns, which matters for a cooling product, since how warm a topper sleeps is hard to judge before you try it. The page listed it at $199 when we checked. The limits are the 1-year warranty and the 2-inch depth, which suits side sleepers on a slightly firm bed more than anyone who wants a big change in feel.

This Sleep Innovations topper pairs two layers: gel memory foam infused with real green tea, and a fiberfill pillow top sewn into a machine-washable cover. The company describes the feel as medium plush, with memory foam that adapts to your body and a pillow top that cushions any sleep position. For heat, Sleep Innovations points to the cooling gel and to breathable, open-cell foams that it says are designed to alleviate heat, while the green tea is meant to keep the surface feeling fresh. Sizes run from twin to California king, and prices ranged from $189.99 to $259.99 when we checked. A 10-year warranty covers the topper, which is long for this price. The weak spot for very hot sleepers is the fiberfill top: it adds plushness, but it is a quilted layer rather than a cooling fabric, so those who sleep the hottest should look at the copper or GlacioTex picks above.

Avocado's Eco Organic topper is here for hot sleepers who want to skip memory foam altogether. It is natural latex: medium GOLS-certified organic Dunlop for firmer support, or Pure Talalay for a plusher, more contouring feel, which costs $80 more. You can pick 2 inches, which Avocado calls a comfort refresh, or 3 inches for $40 more, which it says is its most popular height and suits side sleepers. Avocado says latex springs back quickly, without the slow, stuck feel of memory foam. The organic cotton cover is not removable by design, and an organic cotton canvas base helps keep the topper from slipping. Certifications include GOTS, GOLS, Greenguard Gold, OEKO-TEX Standard 100 Class I and MADE SAFE. It was $199 on sale in the default 2-inch configuration when we checked, down from $249. Note that Avocado does not market this topper as a cooling product, and the warranty is 1 year.

The Birch Plush Organic topper is made by Birch, a natural mattress brand that is now sold on the Helix store. It is a 2-inch layer of organic cotton and latex that Birch says gives plush, deep body contouring and is cool and breathable to maximize airflow for temperature regulation. It carries GOLS and Greenguard Gold certification and is made without polyurethane foams, fiberglass, pesticides or formaldehyde. Birch says it is heavier than typical toppers, so it stays put without straps. Like other Helix products, it is assembled in Arizona, ships free in the US and comes with a 120-night trial; the warranty is 1 year. The price is the problem: a queen was $426 with a 20% code when we checked, against a $532.50 list price, roughly double Avocado's latex topper. You pay a premium for the organic cotton build and the Birch name.
